Description
Technical field
In particular it is ice and snow area rubber grain asphalt the present invention relates to granulated crumb rubber asphalt mixture technical field
The method of compound application technology.
Background technology
In cold winter, many highways and urban roads frequently suffer from the harm of ice and snow, are substantially in ice when snowfall is larger
Snow pavement state, ice and snow substantially reduces coefficient of road adhesion, causes car skidding, braking distance significantly to extend, or even brake
Failure, direction out of control, cause serious traffic accident.These problems turn into traffic safety and people's life, property safety
Major hidden danger, therefore ice and snow road problem annoyings road maintenance department always.The most area of China belongs to ice-snow field
Area, road snow ice formation issues are relatively conventional.Especially early winter and season in the early spring, road snow is in temperature change and vehicular load
In the presence of, road surface easily forms thin ice, influences traffic safety.Because road snow freezes, tire and ground
Attachment coefficient is low, and ground can be supplied to the adhesive force of automobile accordingly to diminish.On general dry bituminous paving or concrete road surface,
Attachment coefficient is about 0.6, and the attachment coefficient for avenging road is 0.2, and the attachment coefficient on ice road is 0.15, respectively dried asphalt road
The 1/3 of attachment coefficient and 1/4.Therefore, the traffic safety of ice and snow road how is efficiently solved, it is to avoid traffic accident goes out to hand over less
Interpreter's event, improves road passage capability and operation benefits, forms good safety management mode, it has also become the area friendship of puzzlement ice and snow
One of major issue of logical administrative department.In order to eliminate the safety risks on road surface under icy conditions, road maintenance department is also normal
Often take measures to remove ice and snow on road surfaces.The method of conventional road surface deicing snow is to dispense alcohols or salt Snow Agent on road surface to make
Ice dissolution, but the deicing effect of alcohols Snow Agent is influenced by environmental temperature, and with anti-icing phenomenon, i.e., once
Environment temperature decline, the accumulated snow being melted can glaciation again, make road surface more sliding, road accident rate is higher.Most of salt
All there are corrosivity, perishable destruction road structure and motor vehicles in class Snow Agent product, can also be to soil, water body and air etc.
Pollute, destroy ecological environment.Rubber grain road surface is that waste and old rubber tyre is broken into definite shape and particle diameter
Particle, instead of part gather materials, the road surface of the making in asphalt is directly mixed in the form of aggregate.Due to rubber
Rubber grain in grain road surface has larger elastic deformability, can effectively improve the deformability on road surface, improves ice and snow
With the bond state on road surface, road snow icing can effectively be suppressed by seif-citing rate under Vehicle Load, therefore, will be useless
Old tire rubber grain is one of the effective way for solving current Problems for road construction.
The content of the invention
The present invention solves the technical problem of the side for providing ice and snow area granulated crumb rubber asphalt mixture application technology
Method, this method is practical, in the case of ice and snow road, can effectively suppress road snow icing, so as to be seasonal ice
The ice and snow on road surfaces problem that suppresses in frozen ground area provides new solution.
In order to solve the above technical problems, the present invention relates to granulated crumb rubber asphalt mixture technical field, being in particular
The method of ice and snow area granulated crumb rubber asphalt mixture application technology, described method is comprised the following steps：
（1）The pitch that used when mixing and stirring of compound is SBS modified pitch, TPS modified pitch, and heating-up temperature is 175 DEG C, scene
SBS modified pitch is heated to 175 DEG C during construction, and TPS modifying agent is manually delivered into cylinder is mixed, and matrix pitch heating-up temperature is no more than
165 DEG C, the heating and temperature control of building stones is mixed and stirred the building stones of heat with rubber grain more than 190 DEG C in advance, is then added again
Enter pitch and miberal powder is mixed and stirred, manually rubber grain is added while hot aggregate bin building stones enter and mix cylinder.
（2）The pollutant of sub-layer during mixture laying, is thoroughly cleaned, rinses, mortar and other scum silica frost application steel brushes are wiped
Clearly, if any water mark, then must not be paved in the case of wet road surface, the pit of sub-layer, loose and other diseases should be by
Specification regulation is repaired with asphalt, and absolute altitude, horizontal wall inscription, flatness to sub-layer will be detected, to influence quality and nothing
Method during the defect location that upper layer is eliminated carries out leveling, upper layer construction before, in the case of free of contamination, will spread adhesion coating
Pitch, sticking layer oil consumption presses specification spread, and answers spread uniform, and the local artificial benefit of location application spilt less or spill more is spilt or clearly
Remove, mixture laying temperature is strictly performed by code requirement, before paving every time, detects and adjust screed, it is ensured that straight, is started
Before paved mixture, screed is preheated, output condition when paving according to compound determines an appropriate speed, entirely paves
Continuously, at the uniform velocity, spreading quality is observed at any time, it is found that isolation and other abnormalities should in time analyze reason, processed, expect
Car is removed in time in the material that the area that paves is scattered.
（3）During compacting pitch, using double steel wheel formula vibrated rollers, every road roller forward-reverse is 1 time, adopts 1/2
Mistake wheel, road roller is first travelled opens vibration again, first closes vibration stagnation of movement again, and granulated crumb rubber asphalt mixture is adopted SMA-16 grades and matched somebody with somebody, rolls
When by driving wheel towards paver, the road roller of first pressing the online lap-joint that paves, two edge carry out roll one time, for rubber
The rebound characteristics of glue particle, the appropriate rolling layer for increasing final pressure, control rolls finishing temperature less than 70 DEG C.
As the further optimization of the technical program, ice and snow area of the present invention granulated crumb rubber asphalt mixture application technology
The temperature of being mixed and stirred when mixing and stirring of the compound described in method is 180 DEG C.
As the further optimization of the technical program, ice and snow area of the present invention granulated crumb rubber asphalt mixture application technology
The mixing time after pitch and miberal powder that added when mixing and stirring described in method is respectively 90 seconds.
The method of ice and snow of the present invention area granulated crumb rubber asphalt mixture application technology has the beneficial effect that：
The method of ice and snow area of the present invention granulated crumb rubber asphalt mixture application technology, this method is practical, in ice and snow road
In the case of, can effectively suppress road snow icing, so that for the suppression ice and snow on road surfaces problem of seasonal freezing region is provided
New solution.
