Description

Composite roadway fabric
Invention field
The present invention relates generally to be used for the reinforcing waterproof construction of waterproof, and be particularly related to the reinforcing road structure.
Background of invention
Because have the very good mechanical properties under weather resistance and the heavy load, the surface in many outdoor places all applies pitch.Pitch is the black cementing properties material of being made up of pitch basically.Present most of pitch is mainly used in paving and waterproof by obtaining in the gasoline treating process.Under normal operating temperature, pitch is viscoelastic; At high temperature begin to be clamminess.
The water proofing property of pitch layer is vital to its durability.The pitch water imbibition that dissolving salt content is lower is poor.When pitch absorption moisture, it begins to feel like jelly and peeling.Also known bacterium and fungi are attacked the low-molecular-weight asphalt material.In addition, the pitch thin layer of exposure sclerosis and cracking will occur being exposed to strong ultraviolet radiation following time.
Known tar sand glue comprises mineral (comprising glass) filler, and it adds with the mobile performance that influences them and reduces cost.Verified mineral-filled thin layer can prevent that it from high temperature flowing the spreading property of improved resistance to impact and anti-flame.Filler also can increase the water imbibition of pitch, and it comprises grinding stone lime stone, slate flower (slate flowers), subfractionation silica, collects rock and mica.Opaque filler can avoid the infringement of weather, and because asbestos packing has filamentary structure, can add to improve toughness.Asbestos fibre has added the tolerance that increases in the mixture of tar paving communications and transportation, and is used for roofing, can prevent fires.
Existing several different methods is used for reinforcing and/or anti-bitumastic solution and concrete paving and similar structures, comprises new structure and existing structure.Which floor great majority all must install again in the workplace.For example, the product of Owenscorning Fiberglass, road vitreum comprise that the pitch base glue with fusion is applied to target surface, with after-applied glass layer, add pitch glue extra play then and prepare composite reinforcing structure.
The non-woven fabrics fabric that Atlantic Construction Fabrics company makes such as Petromat, mainly is as the waterproof roadbed before the pitch wearing layer applies.Petromat is the polypropylene non-woven fabric fabric of pin perforation.Described fabric promptly means a side fusion of described fabric through heat bonding, to prevent that water from penetrating viscous coating and arriving the bottom road surface.Petromat has low relatively modulus of elasticity, and has limited anti-reflection crack.
U.S. Patent No. 4,151,025 discloses a kind of method of concrete bridge deck waterproof, and it comprises the described bridge floor of cleaning, applies subbing on bridge floor, coating film on subbing, and apply viscous coating and pitch layer.Described film comprises uncured elastomeric material lower floor, tissue layer and cured elastomeric materials upper strata.Described film is heated to 175 °F and be rolled into volume before with viscous coating uncured pitch lower floor being bonded in bridge floor.Described tissue layer is the open poroid natural or synthetic textiles of individual layer.Failing to disclose described fabric is high strength or high mode material, and it also says described film strength or other physical properties without pre-preg or other preliminary treatment to strengthen it.
U.S. Patent No. 4,699,542 disclose a kind of be used to strengthen tectal method of the pitch that is applied to the bottom paving and device.Earlier apply viscous coating, with the poroid semi-rigid glass layer of opening of after-applied resin dipping to described paving.The asphalt mixtures cover layer puts on described fabric.Described glass fabric has the high resiliency modulus, the expansion that it has improved the tectal intensity of pitch and has stoped the reflection crack in the cover layer.Resin dipping will make described glass-fiber cord have coating, and protect them not to be subjected to internal cause and external cause, such as friction between the rope and water, and the infringement that particularly use salt on road and corrosion that the water intrusion of the high pH value that forms causes etc. causes.
U.S. Patent No. 4,957,390,5,110,627,5,246,306 and 5,393,559 disclose and have been similar to U.S. Patent No. 4,699,542 system.Wherein be not to adopt viscous coating, described resin dipping glass fabric is bonded in the bottom paving by the hot reaction cement that has on pressure or the fabric.
U.S. Patent No. 5,152 and 5,273,804 disclose a kind of method that adopts open bore/fabric laminate to reinforce covering of roadway.By applying viscous coating, described lamination is placed to roadbed down by fabric side formed covering of roadway subsequently to the bottom roadbed.Then, second viscous coating is applied on the lamination, adds the pitch layer on it.Fabric or braid be can use, continuous fiber or staple fiber preferably used.Described network optimization polypropylene or polyester grid.Described fabric will promote the caking property of lamination and roadbed.Fabric mechanically is connected on the grid by thick grid tubercle, thereby described fabric and grid rope keep at a certain distance away.Interval between described grid and the described fabric makes that covering pitch assembles and penetrate grid and combine with the grid rope, thereby has reinforced described road surface.Although consolidation effect to a certain degree is provided, polypropylene, polyester or similarly plastic grid have relatively low yangs elastic modulus, promptly about 10,000-is about 200, the 000psi order of magnitude.The low modulus material of this class will generally have about 1,000 under corresponding load than (for example), and 000-about 4,000, the fiberglass gridding of 000psi young's modulus stands bigger stress and creep, thereby with respect to the high mode material, it stops the tectal new crack of pitch and reflection crack.
Polyfelt Geosynthetics Group sells the product of a kind of PGM-P by name, and it is the composite consolidation material that is used for pitch.PGM-P comprises the glass fabric of the not coating that is sutured in non-woven fabrics fabric.Without coating, described glass fabric is exposed in the corrosive atmosphere medium, and filament wherein will that glass fiber or fiber are cut off by another root glass fibre be destroyed because of friction and wearing and tearing, and the glass of coating might be destroyed by asphalt road architectural process and application apparatus.In U.S. Patent No. 4,472,086 and 4,540,311 disclose similar products like, and it adopts not that coating, unconvoluted synthetic textiles have replaced not coating glass fiber fabric.
The Chomarat ﹠amp of France Cheylard; Cie sells the product of a kind of Rotoflex by name, and it is the sandwich type clamping in the middle of two nonwoven cloth materials for a kind of coating glass fiber scrim.Described fabric any one face down all can, described nonwoven cloth material has promoted fabric and viscous coating bonding.The shortcoming of Rotoflex fabric is that nonwoven cloth material is located at the upper and lower surface of fiberglass scrim, general aggregation in tar concrete can not infiltrate nonwoven cloth material effectively, and combines the characteristic with the high mode/low creep that makes full use of described scrim with scrim.
Therefore, the advantage of road fabric is that it has the Ideal Match technical characterictic, and promptly watertight composition has the high mode/low creep properties of glass fiber material, and the viscosity of nonwoven cloth material strengthens characteristic.
The invention summary
Road fabric of the present invention is a composite component, and it consists essentially of the ground floor open grid, biaxial stretching, high mode/low creep fibrous material is arranged, protection is essentially the second layer of waterproof material.Described ground floor is with the resinite material pre-preg compatible with pitch, and the preferred waterproof material of described road fabric is down to strengthen the bonding of fabric to the bottom roadbed.The ground floor open grid combines with aggregation in the tar concrete.In this process, the high mode of open grid material/low creep properties can be used for stoping the pitch cracking of covering, and it is new crack or the reflection crack that caused by bottom roadbed cracking.Second layer waterproof material has promoted the caking property of bottom road bed and road fabric and the water proofing property of roadbed.

Detailed Description Of The Invention
Referring to Fig. 1., composite roadway fabric of the present invention can be applicable in new road construction and the existing road construction, preferably include ground floor (10) and be scrim or weave mesh structure, be preferably open grid, two axial being provided with have at least about 250 pounds/inch, be preferably greater than 300-500 pound/inch hot strength, be preferable at least 400 fabrics with heat endurance.Described grid can be made by the continuous glass fibre wire rope, and it has at least about 1,000, the modulus of elasticity of 000psi, and other high modulus fibres are such as the polyester fiber of poly-(to the phenylene terephthalamide), and commodity are called KEVLAR Can use, as long as described configuration can provide enough intensity and can allow fusion pitch permeate like a cork this building, then various Denier and grid configuration all can use.Preferred about 5000 spies' of heavily about 300-ECR or E glass rove.These ropes, preferably low coiling degree (promptly about per inch one changes following), the grid of formation rectangle or square hole, size of mesh opening can be 0.125 inch-6 inches at an end, about 0.5 inch of preferred 0.25-.Described grid is preferably sewed up or otherwise is connected on the node of horizontal and vertical rope.This connection has guaranteed the intensity of grid configuration, prevents before dipping or rope described in the dipping process optionally moves, and has preserved perforate.
The macrolattice perforate makes asphalt mixtures each root rope in embedding yarn or the rove up hill and dale, and makes and combine basically between aggregation and the latticed ground floor 10 in the tar concrete.This makes the stress of durable lamination of pitch or roadbed pass to glass fibre basically, has therefore increased the intensity of the durable lamination of pitch.Ground floor 10 has high resiliency modulus and high strength/cost ratio, and its coefficient of expansion is near roadbed material, and can stop the material that uses in the roadbed and be present in material in the roadbed environment, such as the salt in the road, and the corrosion of formation.
The fixedly connected intensity that also helps grid on grid node partly passes to another row parallel rope because their tolerables are parallel to the power of a row rope.Simultaneously, glass use amount during this open mesh structure can reduce every square yard, so this product is more economical.For example, although can use the grid of every square yard of heavy 4-18 ounce, existing preferred heavily about 12 ounces every square yard grid, as a comparison, some road ruggedized constructions of the prior art adopt the grid of every square yard in heavily about 24 ounces of glass.
Preferably inserting braiding apparatus at warp knitting, parallel adopts the polyester of 70-150 Denier that described grid node is stitched together.But other formation have the method for the grid of fixedly connected node also can be used.For example, the nonwoven grid made from thermal finalization or thermoplastification adhesive is the grid that suits.
After grid is made, before it is positioned on the paving, apply resin.That is, described grid is with resin " pre-preg ".
The viscosity of resin is through selecting the permeable grid rope that enters.Although each rhizoid in the described resin embedding glass fibre rope, the general disperse equably of resin is in the inside of described rope.Dipping makes grid compatible with rope, and it is semi-rigid that it is had, and described glass rope is through lining and avoid water and the erosion of other factor.Dipping also reduces the wearing and tearing between glass rope or silk, and glass rope or silk cut off by another root glass rope or silk, this point described grid fallen and described pitch cover layer particularly important before applying.
Although have resin dried or that solidify on grid, rope has been driven plain a bit, and described latticed perforate still is held.For example, in a preferred embodiment, form rectangular mesh, rove flattens to 1/16 inch, therefore is about below 1/32 inch in coating and dried rove thickness.
Various kinds of resin can be used for flooding grid, if this kind adhesive and their bondings are good.Main embodiment is pitch, modified rubber pitch, crosslinked and non-crosslinked acrylic compounds and polyvinyl alcohol, unsaturated polyester, vinyl acetate, epoxies, polyacrylate, polyurethanes, polyolefin and the phenolic resins with required hardness, compatibility, corrosion resistance and heat endurance.They can the heat fusing body, emulsion, solvent, heat cure or radiation curing form apply.Perhaps, can serve as a contrast through the pitch emulsion of polymeric material such as acrylic polymer modification and be applied on the grid and heat cure.The pitch of this modification less coating that can be ftractureed at low temperatures.
Composite roadway fabric of the present invention further preferably includes second material layer 30, and it can be fabric, or is preferably the non-woven fabrics fabric that stops water to pass through basically.Its hear resistance can be at least 400 °F, and the bottom road has water-proof function after combining of compound fabric structure and road strengthens.Because purchase is convenient and cost is cheap relatively, preferred non-woven fabrics fabric is all Petromat as the aforementioned of a pin perforation polypropylene fabric product.Other suitable non-woven fabrics fabric comprises binding material, braided material and the pin perforation polyester that is spun into.About 2-8oz/yd in the preferred non-woven fabrics fabric 2, and be preferably about 3-5 oz/yd 2But as long as it has been applied to or has can be used for waterproofing performance of roads, the actual grade of non-woven fabrics fabric, composition or source are not very important.
Composite roadway fabric structure of the present invention can prepare by several different methods.For example, the ground floor 10 and the second layer 30 can by sew up 40, peg with and mechanically combination of similar fashion.In addition, a kind of pressure-sensitive and/or heat sensitive adhesive can be applied to one or two in the ground floor and the second layer 10,30, presses together subsequently, can heat if necessary.As further replacement, the second layer 30 can combine by the resinite material and the ground floor 10 of dipping ground floor 10.That is, described ground floor 10 can be through resin dipping and coating, and the described second layer contacts with ground floor 10 by resin solidification and combines.Further, the pitch emulsion can be sprayed on the ground floor and the second layer 10,30 or these layers are soaked in about 400-420 the fusion glue pond having temperature.The described ground floor and the second layer 10,30 not damaged during through a pair roller in coating and binding process, and the coating compound fabric of gained with described cement cutting and be rolled into easily shape such as volume or sheet before externally under the temperature or dry in drier.
But preferred contact adhesive 20 is a U.S. Patent No. 5,110, and 627 (this article draws in this for referencial use) are disclosed, and it can be used as the reagent that the ground floor of compound fabric and the second layer 10,30 are bonded to each other.Suitable adhesive comprises synthetic elastic gum and synthetic thermoplastic adhesive.Acrylic compounds, SBR styrene butadiene rubbers are wherein arranged, tackify pitch and tackify olefine.
When adopting compound fabric to implement road to overhaul, can implement the standard surface preparation of bottom tar concrete or portland cement concrete road road surfaces, comprise matrix repairing, shutoff crack, hollow is filled up and analog.Apply viscous coating and described fabric is unfolded and is pressed on road surface at road surface.Compound fabric can be positioned over the bottom road surface down by first clathrum.On the best grid surface of described compound fabric is super, make the tectal the best that combines of itself and pitch.Replace the viscous coating that is applied to road surface, aforementioned adhesion agent coating can put on the surface of compound fabric in advance arbitrarily, thereby the contact bottom layer road is with the bonding between promoting.Similarly viscous coating or adhesive can put on the another side of compound fabric to promote that fabric combines with pitch is tectal.Placing described compound fabric and after any viscous coating/adhesive of described bottom road surface and/or compound fabric, having the pitch layer of suitable depth and composition (HL 1 tar concrete of 50mm according to appointment), can conventional equipment and technology apply.
Gained is reinforced road structure can make the bottom waterproofing performance of roads effectively, and can prevent that supratectal new crack of pitch and reflection crack from forming.
Previous embodiment is explained the present invention in detail; be understandable that; it only is used to explain the present invention, and for non-those of ordinary skill in the art, modification and conversion that any spirit and scope that do not break away from claim of the present invention are done all should drop within protection scope of the present invention.
