Description
Technical field
The utility model belongs to field, pitch mixing road surface, particularly a kind of modified asphalt mixture road surface.
Background technology
Along with scientific and technological progress, the raising of people's living standard, the vehicle that road travels gets more and more, also just more and more higher to the requirement of road.Flexible pavement is smooth with it, comfortable, noise is little, dust is little, easy to maintenance, be beneficial to mechanized construction, become the first-selection of road without advantages such as preserving period.But meanwhile, it is relatively short that asphalt road also also exists the life-span, the shortcoming of the poor grade of cling property.
Utility model content
In order to solve the problem, the utility model has designed and developed a kind of modified asphalt mixture road surface, comprises from top to bottom:
Modified bitumen surface layer, sealing, permeable layers and basic unit, wherein,
Described basic unit comprises basic unit and cement stabilized soil subbase on Asphalt Stabilized Macadam;
Described cement stabilized soil subbase comprises a steel bar framework and is filled in the cement stabilized soil of described steel bar framework inside; Described steel bar framework comprises vertical reinforcing bar and steel mesh reinforcement, and described vertical reinforcing bar perpendicular to the arrangement of ground surface rectangular array, and is divided into overground part and under ground portion by described earth's surface; Described overground part height is 150mm; The intertwined point of described steel mesh reinforcement is as the upper surface one_to_one corresponding of institute's overground part and be welded to connect.
Preferably, in described modified asphalt mixture road surface, basic unit on described Asphalt Stabilized Macadam, thickness is 80mm.
Preferably, in described modified asphalt mixture road surface, described cement stabilized soil is gone to a grassroots level, and thickness is 200mm.
Preferably, in described modified asphalt mixture road surface, described modified bitumen surface layer comprises surface layer and high-strength modified asphalt cutting optimal in Modified Asphalt Friction surface course, high-strength modified asphalt from top to bottom;
Described its bituminous mixture of Modified Asphalt Friction surface course adopts AK-13, and thickness is 45mm;
In described high-strength modified asphalt, its bituminous mixture of surface layer adopts SBS-20, and thickness is 50mm;
Described its bituminous mixture of high-strength modified asphalt cutting optimal adopts SBS-25, and thickness is 65mm.
Preferably, in described modified asphalt mixture road surface, described sealing comprises sealing and detritus under-sealed layer on modified emulsifying asphalt thin pulp;
On described modified emulsifying asphalt thin pulp, its bituminous mixture of sealing adopts ES-25, and thickness is 5mm;
Described detritus under-sealed layer, thickness is 5mm.
Preferably, in described modified asphalt mixture road surface, described permeable layers is liquid petroleum primary coat, and thickness is 6mm.
In the infrastructure of the utility model flexible pavement, subbase is by steel bar framework and the effect of cement stabilized soil being filled in described steel bar framework inside, improves the ability that Asphalt Pavement Base bears the vehicle vertical load transmitted by surface layer.Meanwhile, using modified asphalt mixture as surface layer structure, improve high temperature resistant, the cryophylactic ability on pitch mixing road surface, have good rutting resistance, improve the anti-slide performance supporting capacity on road surface.
Accompanying drawing explanation
Fig. 1 is the vertical section structural representation on modified asphalt mixture road surface described in the utility model;
Detailed description of the invention
