Abstract
A bituminous concrete pavement composite sandwich construction for delaying upward extension of reflective cracks comprises an upper bituminous concrete layer, a middle bituminous concrete layer, a lower bituminous concrete layer, a water stable base layer or cement base layer and a soil base layer, which are arranged in sequence from the top down; glass fiber high-polymer crack-resistance patching layer is arranged between the upper bituminous concrete layer and the middle bituminous concrete layer, between the middle bituminous concrete layer and the lower bituminous concrete layer, or between the lower bituminous concrete layer and the water stable base layer or cement base layer; the thickness of the glass fiber high-polymer crack-resistance patching layer is 2.0mm to 3.0mm; and the high polymer layer adopts asphalt-based high polymer. The utility model has the advantages that the service life of the pavement can be prolonged, and the crack-resistant patch forms an integrated waterproof and seepage-proof layer, so that rainwater and snow moisture on the pavement can be prevented from seepage downwardly toward the roadbed, which protects the strength of the base layer.
Description
Technical field
The utility model relates to the upwards asphalt concrete pavement composite sandwich construction of development of a kind of delayed reflex crack.
Background technology
Highway the crack occurs through regular meeting between supercrust in use for some time, if transmit in the crack of leaving, will cause bigger influence to road conditions.For fear of the appearance of this situation, more advanced in the industry way is to lay anti-splitting paster between supercrust, upwards transmits thereby effectively suppress the crack.Present anticracking material mostly is single layer structure, and effect of prestressed is relatively poor; Also have and adopt lamination layer structure, but because the setting of selection of layer material at present and layer unreasonable, the result of use of anti-splitting paster is unsatisfactory.
The utility model content
The utility model provides the upwards asphalt concrete pavement composite sandwich construction of development of a kind of delayed reflex crack, delays the upwards development of base course reflection crack, has greatly reduced asphalt pavement crack, has prolonged the application life on road surface; Anti-splitting paster forms the complete water proof impervious barrier of one deck, and road surface capable of blocking rain, snow-broth divide to descend to ooze to roadbed, thus the intensity of protection basic unit.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of delayed reflex crack is the asphalt concrete pavement composite sandwich construction of development upwards, comprises in bituminous concrete upper layer, the bituminous concrete surface layer, the steady basic unit of water or cement basic layer, soil matrix layer under surface layer, the bituminous concrete from top to bottom successively; In bituminous concrete upper layer and bituminous concrete between the surface layer or in bituminous concrete under surface layer and the bituminous concrete between the surface layer or be provided with glass high polymer cracking resistance paste layer under the bituminous concrete between steady basic unit of surface layer and water or the cement basic layer; Described glass high polymer cracking resistance paste layer from top to bottom is composited by glass fabric layer, high polymer layer, tire base, high polymer layer successively.
The thickness of described glass high polymer cracking resistance paste layer is 2.0-3.0mm.
Described high polymer layer adopts the high molecular polymer of asphaltic base.
The utility model has the advantages that:
1, delays the upwards development of base course reflection crack, greatly reduced asphalt pavement crack, prolonged the application life on road surface;
2, the polymeric material of anti-splitting paster can form the complete water proof impervious barrier of one deck, and road surface capable of blocking rain, snow-broth divide to descend to ooze to roadbed, thus the intensity of protection basic unit.

The specific embodiment
A kind of delayed reflex crack is the asphalt concrete pavement composite sandwich construction of development upwards, comprises in bituminous concrete upper layer 1-1, the bituminous concrete surface layer 1-3, the steady basic unit of water or cement basic layer 3, soil matrix layer 4 under surface layer 1-2, the bituminous concrete from top to bottom successively; In bituminous concrete upper layer 1-1 and the bituminous concrete between the surface layer 1-2 (shown in the embodiment 1 of Fig. 1) or under surface layer 1-2 and the bituminous concrete in the bituminous concrete between the surface layer 1-3 (shown in the embodiment 2 of Fig. 2) or under the bituminous concrete between steady basic unit of surface layer 1-3 and water or the cement basic layer 3 (shown in the embodiment 3 of Fig. 3) be provided with glass high polymer cracking resistance paste layer 2.As shown in Figure 4, glass high polymer cracking resistance paste layer 2 from top to bottom is composited by glass fabric layer 5, high polymer layer 6, tire base 7, high polymer layer 8 successively.Glass high polymer cracking resistance paste layer 2 costs can be made the coiled material that is provided with barrier film 9, and barrier film 9 is for being attached with the PE film of silicone oil; The thickness of glass high polymer cracking resistance paste layer 2 is 2.0-3.0mm; High polymer layer 8 adopts the high molecular polymer of asphaltic base.
The utility model can be widely used in: basic unit the milling in crack occurs or mends the surface by replacing a damaged part; Cement pavement transform the cement surface (changing the project on black road surface in vain) in the flexible pavement as.
