Abstract
The utility model discloses a waterproof and stress-prevention pitch road, and relates to a road structure. The waterproof and stress reflection pitch road comprises a base layer, a pitch surface layer and a rubber pitch stress absorbing layer arranged between the base layer and the pitch surface layer. The waterproof and stress reflection-prevention pitch road can resist water and stress reflection.
Description
Technical field
The utility model relates to a kind of road structure, relates in particular to a kind of asphalt roads.
Background technology
Existing asphalt roads is at present at semi-rigid type base or above the cement concrete pavement, directly the making flexible pavement.Risk below present asphalt roads exists:
1, the crack of semi-rigid type base or cement concrete pavement is easy to reflex to the asphalt road surface;
2, can not waterproof: the water on top layer, asphalt road surface be easy to accelerate the damage on roadbed, road surface the deck below the crack of reflection is penetrated into.
The utility model content
The purpose of the utility model is the defective to prior art, proposes the asphalt roads of a kind of waterproof, anti-stress reflexion.
The purpose of the utility model realizes through following technical proposals: the asphalt roads of a kind of waterproof, anti-stress reflexion, comprise basic unit and asphalt surface course, and also comprise the stress absorbing layer of being located between basic unit and the asphalt surface course.
As optimal way, said stress absorbing layer is the rubber asphalt layer.As optimal way, stress absorbing layer also comprises the macadam on the bonding surface of being located at rubber asphalt layer and asphalt surface course.
The beneficial effect of the utility model: the rubber asphalt layer is at the high viscoelastic soft interlayer that forms between asphalt surface course and the basic unit about thickness lcm; Further pass through the interlock action of the macadam on the bonding surface again; Surface layer and basic unit's connection are become integral body; The strain that causes the displacement of place, crack basic unit is dissipated in the interlayer scope, effectively alleviates the stress concentration phenomenon of asphalt surface course bottom surface, basic crack place, plays the effect of containment basic crack to the surface layer expansion; The viscoelastic soft interlayer of this floor height has been filled the slit of surface layer and basic unit, prevents to ooze under the moisture, plays the effect of seal; Simultaneously high viscoelastic soft interlayer can make the firm absorption of surface layer be bonded in the basic unit, makes road structure form unified integral body, plays a role jointly; When the rubber asphalt stress absorbing layer combined with the rubber asphalt surface layer to lay, further the laying depth of attenuate rubber asphalt surface layer was practiced thrift construction cost.
Description of drawings
Fig. 1 is the sectional view of the utility model embodiment one;
Fig. 2 is the sectional view of the utility model embodiment two;
Among the figure, 1 is basic unit, and 2 is asphalt surface course, and 3 is the rubber asphalt layer, and 4 is macadam.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.
Embodiment one:As shown in Figure 1, the asphalt roads of a kind of waterproof, anti-stress reflexion comprises basic unit 1 and asphalt surface course 2, also comprises the stress absorbing layer of being located between basic unit 1 and the asphalt surface course 2, and said stress absorbing layer is a rubber asphalt layer 3.
Embodiment two:As shown in Figure 2, except that the basic structure of embodiment one, also comprise the macadam 4 on the bonding surface of being located at rubber asphalt layer 3 and asphalt surface course 1.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
Claims (3)
1. the asphalt roads of a waterproof, anti-stress reflexion comprises basic unit and asphalt surface course, it is characterized in that: also comprise the stress absorbing layer of being located between basic unit and the asphalt surface course.
2. the asphalt roads of waterproof as claimed in claim 1, anti-stress reflexion, it is characterized in that: said stress absorbing layer is the rubber asphalt layer.
