Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of based on steep slope road section Heavy Duty Freight Car antiskid
The front and back of asphalt pavement structure, including permeable roadbed 1, permeable roadbed 1 is provided with drainage ditch close to the position of bottom
2, due to draining, the top of permeable roadbed 1 has been placed equidistant with crossbeam 3, increases pavement strength, extends the use intensity on road surface, thoroughly
Porous disc 6 is laterally placed equidistant in water route base 1, convenient for moisture penetration into aqueduct 7, adjacent two are arranged in porous disc 6
Underface between a crossbeam 3, the top of drainage ditch 2 has been placed equidistant with aqueduct 7, and the top of aqueduct 7 connects porous disc 6
Bottom, the surface of permeable roadbed 1 and crossbeam 3 is equipped with pervious bed 4, and the top of pervious bed 4 is provided with asphalt surface course 5, as
The top of surface structure, crossbeam 3 is trapezium structure, and pervious bed 4 and 5 trapezium structure of asphalt surface course are upward, pervious bed 4 and drip
It is provided with groove corresponding with protrusion between the two adjacent crossbeams 3 in the surface on green surface layer 5, increases the friction with vehicle tyre
Power prevents brake failure.
Wherein, crossbeam 3 includes precast concrete 31, and the surface of precast concrete 31 has been placed equidistant with diversion trench 32,
Convenient for draining, the cross section of precast concrete 31 is the bar shaped bent to the right along middle position, makes the recessed of 5 surface of asphalt surface course
Slot inclination bending, convenient for draining；
The section of diversion trench 32 is that bottom width is diminishing triangular, and the depth of diversion trench 32 along it is intermediate respectively to
Front and back is gradually deepened, and the inner cavity connection of the front and back difference permeable roadbed 1 of purposes of diversion trench 32, convenient for fast
Water is discharged speed；
The thickness of pervious bed 4 gradually decreases respectively to front and back along centre, provides resistance for sideslip vehicle vehicle, and
