Abstract
The utility model discloses a kind of cracking resistance flexible pavement, comprise ground, basic unit, lower laying, intermediate layer, upper laying; Described ground, basic unit, lower laying, intermediate layer, upper laying are laid from top to bottom successively; Described basic unit is bituminous macadam pavement; Described lower laying is the flexible pavement adding butadiene-styrene rubber; Described intermediate layer is for adding poly flexible pavement; Described upper laying is asphalt concrete pavement; It is characterized in that: also comprise crack-resistant layer; Described crack-resistant layer is laid on the upper of laying; Described crack-resistant layer is the rubber-asphalt mixture road surface adding glass fiber; The utility model adds crack-resistant layer, and crack-resistant layer adopts the rubber-asphalt mixture adding glass fiber, and this compound can avoid the cracking on road surface effectively, serves the effect on protection road surface.
Description
Technical field
The utility model relates to a kind of road structure, particularly relates to a kind of asphalt pavement structure with anti-cracking function.
Background technology
Flexible pavement is the various types of road surfaces participating in bitumen for road use material making in mineral material, and asphalt binder improves the ability of paving the way with pellet opposing driving and the infringement of natural cause road pavement, makes the few dirt of evenness of road surface, waterproof, durable in use; Therefore, flexible pavement is a kind of high class pavement being put employing by most light in road construction;
But, at present, road after long-term roll extrusion, road all there is splitting in various degree, therefore, road needs often to maintain, and even changes, and this just decreases the application life of flexible pavement virtually.
Summary of the invention
The utility model is in order to make up the deficiencies in the prior art, and provide a kind of flexible pavement with anti-cracking function, road surface can be protected effectively in this road surface, avoids road surface to split;
For achieving the above object, the technical scheme that the utility model is taked is:
A kind of cracking resistance flexible pavement, comprises ground, basic unit, lower laying, intermediate layer, upper laying; Described ground, basic unit, lower laying, intermediate layer, upper laying are laid from top to bottom successively; Described basic unit is bituminous macadam pavement; Described lower laying is the flexible pavement adding butadiene-styrene rubber; Described intermediate layer is for adding poly flexible pavement; Described upper laying is asphalt concrete pavement; It is characterized in that: also comprise crack-resistant layer; Described crack-resistant layer is laid on the upper of laying; Described crack-resistant layer is the rubber-asphalt mixture road surface adding glass fiber;
The thickness of described crack-resistant layer is 24 ~ 28cm;
Compared with prior art; adopt such scheme, the beneficial effects of the utility model are: the utility model adds crack-resistant layer, and crack-resistant layer adopts the rubber-asphalt mixture adding glass fiber; this compound can avoid the cracking on road surface effectively, serves the effect on protection road surface.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, a kind of cracking resistance flexible pavement, comprises ground 6, basic unit 4, lower laying 5, intermediate layer 3, upper laying 2; Described ground 3, basic unit 4, lower laying 5, intermediate layer 3, upper laying 2 are laid from top to bottom successively; Described basic unit 4 is bituminous macadam pavement; Described lower laying 5 is for adding the flexible pavement of butadiene-styrene rubber; Described intermediate layer 3 is for adding poly flexible pavement; Described upper laying 2 is asphalt concrete pavement; It is characterized in that: also comprise crack-resistant layer 1; Described crack-resistant layer 1 is laid on the upper of laying 2; Described crack-resistant layer 1 is for adding the rubber-asphalt mixture road surface of glass fiber;
The thickness of described crack-resistant layer 1 is 24 ~ 28cm; Both meet user demand, ensure again good effect of prestressed;
The utility model adds crack-resistant layer, and crack-resistant layer adopts the rubber-asphalt mixture adding glass fiber, and this compound can avoid the cracking on road surface effectively, serves the effect on protection road surface;
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, done all conversion, all drop within protection domain of the present utility model.
