Abstract
The utility model discloses a road surface structure lifted from an old road surface. An lower surface layer is an old bituminous road surface layer or a cement concrete road surface layer which are milled and planed or neither milled nor planed; a waterproof anti-crack layer and an upper surface layer are laid on the lower surface layer in order; or a modified asphalt broken stone stress absorbing layer is additively laid on the waterproof anti-crack layer. The road surface structure lifted from the old road surface is a novel combined structure which is lifted by road surfaces of roads on grades and city roads; after lifting reconstruction, the road surface is prevented from cracking and being damaged by water in the early period; and the road surface has new functions of increased road surface roughness, and drainage of the surface layer, thereby enhancing the driving comfortableness, greatly enhancing the using safety of the road and the city road, prolonging the road service life, reducing the noise, saving the energy and reducing emission, and having significant economic benefit and social benefit.
Description
Technical field
The utility model relates to the technical field that a kind of existing highway promotes its function, and the existing road surface of especially a kind of speedway promotes the road structure of transforming.
Background technology
Existing highway road, its road surface are full compact structure basically, the temperature influence serious cracking, and road surface is closely knit and smooth, and friction factor is little, unfavorable traffic safety, damage by water is bad and rut is serious, and later stage maintenance cost is high.
The lifting transformation of existing highway road is different from common engineering overhaul or transformation, and common overhauling reform only is that road is widened, and adjusts longitudinal gradient and turning radius, is to carry out from the meaning of highway road classification.Also be different from repairing, front cover and the cover maintenance of existing road.The measure that maintenance is taked usually is, old pavement is washed plane, and (also can not milling) after cleaning out, sprays one deck sticking layer oil or seal oil, re-lays one deck bituminous concrete.The road surface that this remodeling method is laid mainly is to recover its function, but is prone to diseases such as the bad and road surface slippery of damage by water, ponding.The art of this patent is meant by promoting the function of use on road surface, makes the road surface safer, and is more comfortable, and more environmental protection is more durable.
The utility model content
The technical problems to be solved in the utility model provides a kind of road structure that damage by water is bad and old pavement lifting raising road function of use (draining, noise reduction, safe, comfortable) is transformed of avoiding.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: its down surface layer for through milling or without the old asphalt pavement layer of washing plane or cement concrete pavement layer, be equipped with water-proof crack-resistant layer and upper layer in the layer below successively.
Preferred water-proof crack-resistant layer is laid with modified asphalt mixture.
Preferred upper layer is a drainage pavement.
As a kind of preferred version of the present utility model, between water-proof crack-resistant layer and following surface layer, be equipped with modified asphalt macadam layer or bituminous macadam; Its effect is the bearing course as the road surface load, and absorbs the thermal cracking and the fatigue crack of old pavement and basic unit, prevents that rut and crack from appearring in surface layer.
Adopt the beneficial effect that technique scheme produced to be: the utility model is a kind of existing highway and urban road surfaces to be risen to more higher leveled novel pavement combining structure, it makes full use of old road, realize the lifting of Pavement Performance by transformation, and be not only original performance or the function of recovering the road surface.The road structure that this lifting is transformed can prevent that the crack from appearring in the road surface and early water damages, prevent rut, increase surface roughness, promote the safety in utilization of highway, urban road significantly, prolong highway, road application life, reduce noise, energy-saving and emission-reduction, economic benefit and social benefit are fairly obvious.
The utility model is that functional performance to existing highway, urban road is by promoting class, its top with the density surface layer on existing road surface is replaced with the drainage pavement surface layer, water-proof crack-resistant layer and modified asphalt macadam layer make it possess the function of waterproof, cracking resistance again, so just improved the road surface functional performance, greatly improve travel safety and comfortableness, prolong road application life, reduce influence degree environment.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the another kind of embodiment of the utility model.
The specific embodiment
Embodiment 1:
Shown in Figure 1, old asphalt pavement 2 is washed plane, after cleaning out, spray one deck sticking layer oil earlier, re-lay one deck modified bitumen stabilization gravel layer 4, thickness is 3-6cm, re-lays one deck water-proof crack-resistant layer 1, thickness is 5-15mm, and layer is laid one deck drainage pavement layer 3 in the above at last, and thickness is 3-4cm.
Embodiment 2:
Shown in Figure 1, after old pavement cleaned out, spray one deck sticking layer oil earlier, re-lay one deck modified bitumen stabilization gravel, thickness is 3-6cm, re-lays one deck water-proof crack-resistant layer, and thickness is 5-15mm, and layer is laid one deck drainage pavement in the above at last, and thickness is 3-4cm.
Embodiment 3:
Shown in Figure 2, old asphalt pavement 2 is washed plane, after cleaning out, spray one deck sticking layer oil earlier, re-lay one deck water-proof crack-resistant layer 1, thickness is 8-20mm, lays one deck drainage pavement layer 3 at last, thickness is 3-4cm.
Embodiment 4:
Shown in Figure 1, after old cement pavement cleaned out, spray one deck sticking layer oil earlier, re-lay one deck pitch stabilization gravel, thickness is 3-6cm, re-lays one deck water-proof crack-resistant layer, and thickness is 5-15mm, and layer is laid one deck drainage pavement in the above at last, and thickness is 3-4cm.
Water-proof crack-resistant layer in the foregoing description preferably selects for use modified bitumen, fiber and the heat of gathering materials to mix the bituminous mixture that mixes.
This existing old pavement promotes the road structure of transforming to be passed through to lay water-proof crack-resistant layer, can prevent that crack and damage by water are bad.Because water-proof crack-resistant layer has good low temperature (15 ℃) extensibility and pulling force, self does not ftracture, and bond effect between the energy enhancement layer, improves the globality of road structure, the passage of the permeable infiltration of blocking-up surface layer lower floor.Lay the modified asphalt macadam stress absorbing layer, can improve the bearing capacity on road surface, prevent rut, and can absorb thermal cracking and fatigue crack from lower floor and basic unit.Lay drainage topping, the void content of its 18%-25% has improved surface roughness, has avoided rainy day water to float and tire water smoke, has improved travel safety, has reduced tire noise.
