Abstract
The utility model relates to a pavement for a crossroad. The pavement is arranged on a road base and comprises a waterproof bonding layer and a track treating layer, wherein the waterproof bonding layer is arranged on the road base, and the track treating layer is arranged on the waterproof bonding layer. The pavement for the crossroad has the advantages of good performances for resisting movement and track. By the aid of the pavement for the crossroad, tracks, movement and cracks of the crossroad can be reduced, the technical puzzle about unstable asphalt pavement for highway construction and maintenance in our country is overcome, and maintenance cost for the asphalt pavement of the crossroad is simultaneously reduced.
Description
Technical field
The utility model relates to pavement engineerings such as highway construction, especially a kind of road structure that is applicable to the intersection.
Background technology
The road surface of Ordinary Rd is layer-built at present, and grain formula, lower floor laid with coarse grain formula asphalt mixture material during the upper strata was used with particulate formula, middle level, and structure forms the upper, middle and lower-ranking road structure.This road structure is generally to have the interlayer soft layer after making is accomplished in the deficiency that exists; Road surface interlayer contact in use is easy to generate deformation failure; Especially in the intersection of road, vehicle through regular meeting bring to a halt, turn round, the lane change speed of a motor vehicle changes and brings certain influence to the resistance to overturning on road surface.
Summary of the invention
The purpose of the utility model is to overcome the easy deficiency that produces deformation failure in intermediate layer, road surface in the prior art, and a kind of road surface that is applicable to the intersection is provided.Specifically realize by following technical scheme:
A kind of road surface that is applicable to the intersection is arranged on the roadbase, comprises water-proof tack coat and rut punishment layer, and said water-proof tack coat is arranged on the said roadbase, and said rut punishment layer is arranged on the water-proof tack coat.
The further design of described road structure is that said rut punishment layer thickness is 6 ~ 17cm.
A kind of novel flexible pavement that the utility model provides; Through on the sub-surface after the milling, water-proof tack coat being set; And on this water-proof tack coat, punish layer for the thick rut of the disposable 6 ~ 17cm that paves; Performances such as the anti-passing of intersection flexible pavement, anti-rut are improved; Reduce the pavement diseases such as rut, passing and crack of intersection, thereby solve flexible pavement unsettled technical barrier in insoluble always intersection in puzzlement highway in China construction and the maintenance, can reduce the maintenance costs of intersection flexible pavement simultaneously.
Description of drawings
Fig. 1 is the road structure that the utility model provided.
Among the figure, 1-rut punishment deck, 2-water-proof tack coat, 3-basic unit.
The specific embodiment
Below in conjunction with Figure of description and embodiment the utility model is described further:
The road surface of the utility model comprises rut punishment layer 1, water-proof tack coat 2, basic unit 3.As shown in Figure 1, rut punishment deck 1 is arranged on the roadbase 3 after the milling, is connected through water-proof tack coat 2 between rut punishment layer 1 and the sub-surface 3.Wherein water-proof tack coat 2 is a mulseal class water-proof binding layer material, and rut punishment layer is the special disposable bituminous mixture that paves of 6 ~ 17cm for thickness.
When carrying out the punishment of intersection pavement rut; At first according to the milling of situation selectivity or the gross area milling of intersection rut; The intact back cleaning of milling substrate surface; Spreading water-proof tack coat 2, treat water-proof tack coat 2 breakdowns of emulsion (about 20 ~ 30 minutes) after, begin to carry out paving of rut punishment deck 1.
Above-mentioned road structure is employed in the road surface of intersection; Have performances such as anti-preferably passing, anti-rut; Can obviously improve the stability on road surface, effectively reduce common pavement diseases such as rut, passing and crack, the maintenance costs of intersection flexible pavement is reduced.
Claims (2)
1. a road surface that is applicable to the intersection is arranged on the roadbase, it is characterized in that comprising water-proof tack coat and rut punishment layer, and said water-proof tack coat is arranged on the said roadbase, and said rut punishment layer is arranged on the water-proof tack coat.
2. a kind of road surface that is applicable to the intersection according to claim 1 is characterized in that said
Rut punishment layer thickness is 6 ~ 17cm.
