Abstract
The utility model belongs to highway construction road structure technical field, specifically, relates to a kind of environmental protection Rut resistance road surface.It is provided with modified bitumen dense-graded asphalt concrete, high-modulus asphalt concrete, cement stabilized macadam base and cement cold in place recycling subbase from top to bottom successively.Compared with prior art, the utility model, by modified emulsifying asphalt tack coat, improves Coating combination ability, reaches interlayer continuous state; By modified emulsifying asphalt synchronous surface dressing, the effect of stress absorbing layer can be played, delay the reflection crack that base-layer contraction cracking causes, improve road surface cracking resistance, can also prevent surface layer moisture from infiltrating basic unit, improve road surface water resistant damage capability; By cement paste tack coat 7, strengthen the Coating combination between basic unit, improve the integrated carrying ability on road surface.Therefore, it has good rutting resistance, endurance quality and low-carbon environment-friendly performance.
Description
Technical field
The utility model belongs to highway construction road structure technical field, specifically, relates to a kind of environmental protection Rut resistance road surface.
Background technology
Rut refers to that distortion is pushed in the densification under the accumulated deformation of the flexible pavement irrecoverable strain under load action is made in repeated rows turner and Driving Loading, is the most general a kind of mode of failure of flexible pavement distortion.Town road asphalt pavement rut generally appears at town road intersection, bus platform wait for bus brake, start position more frequently.In high temperature summer, the surface temperature of flexible pavement is often higher than the softening point of pitch, and supporting capacity declines, and therefore under local function, easily forms rut, causes driving uncomfortable and affects application life of flexible pavement.
During conventional pav maintenance and renovation, substantially be all the road structure excavating original breakage, the road surface structare layer that making is new, so not only can not make full use of original road structure bearing capacity, and excavate road surface waste material and occupy cultivated land, contaminated environment, does not meet environmentally friendly and idea of development that is conservation-minded society.
Summary of the invention
For solving the problems of the technologies described above, the ring that the utility model provides a kind of double energy cracking resistance, water resistant is damaged
Protect Rut resistance road surface.
A kind of environmental protection Rut resistance road surface described in the utility model, described environmental protection Rut resistance road surface is provided with modified bitumen dense-graded asphalt concrete 1, high-modulus asphalt concrete 2, cement stabilized macadam base 3 and cement cold in place recycling subbase 4 from top to bottom successively.
A kind of environmental protection Rut resistance road surface described in the utility model, is provided with modified emulsifying asphalt tack coat 5 between described modified bitumen dense-graded asphalt concrete 1 and high-modulus asphalt concrete 2.
A kind of environmental protection Rut resistance road surface described in the utility model, described high-modulus asphalt concrete 2 is provided with modified emulsifying asphalt synchronous surface dressing 6 between cement stabilized macadam base 3 with it.
A kind of environmental protection Rut resistance road surface described in the utility model, is provided with cement paste tack coat 7 between described cement stabilized macadam base 3 and cement cold in place recycling subbase 4.
A kind of environmental protection Rut resistance road surface described in the utility model, described modified bitumen dense-graded asphalt concrete 1 thickness is 4-5cm, described high-modulus asphalt concrete 2 thickness is 6-8cm, and cement stabilized macadam base 3 is 16-20cm, and cement cold in place recycling subbase 4 thickness is 15-20cm.
Compared with prior art, environmental protection Rut resistance road surface described in the utility model, by modified emulsifying asphalt tack coat, is improved Coating combination ability, is reached interlayer continuous state; By modified emulsifying asphalt synchronous surface dressing, the effect of stress absorbing layer can be played, delay the reflection crack that base-layer contraction cracking causes, improve road surface cracking resistance, can also prevent surface layer moisture from infiltrating basic unit, improve road surface water resistant damage capability; By cement paste tack coat 7, strengthen the Coating combination between basic unit, improve the integrated carrying ability on road surface.Therefore, it has good rutting resistance, endurance quality and low-carbon environment-friendly performance.
