Abstract

The invention discloses a composite asphalt stress absorption membrane and a preparation method thereof, belongs to the field of road construction, and particularly relates to an anti-cracking waterproof sealing membrane applicable to asphalt pavement. The composite asphalt stress absorption membrane comprises a wear-resistant isolation layer, an upper composite layer, a base, a lower composite layer and a protection layer arranged sequentially from top to bottom; the wear-resistant isolation layer consists of quartz sand of 20-40 meshes; the upper composite layer and the lower composite layer both consist of high molecular polymer modified asphalt; a high-density polyethylene (PE) membrane is adopted for the protection layer; the base is high-modulus base cloth; the high-modulus base cloth is polyester filament geotextile or polyester glass fiber cloth. The preparation method comprises the following steps: 1) preparing high molecular polymer modified asphalt of the upper composite layer and lower composite layer; 2) combining the upper composite layer, the lower composite layer and the base; 3) pasting the protection layer and the wear-resistant isolation layer; and 4) cooling, cutting and rolling.

Description

Technical field

[0001] The composite asphalt stress absorbing membrane of the present invention and its preparation method belong to the field of road construction, in particular to an anti-cracking and waterproofing method suitable for adding an asphalt surface layer on an asphalt pavement structure base layer and an additional asphalt surface layer on an old cement road surface Sealing film. Background technique

[0002] With the rapid increase in traffic volume and heavy loads in my country, semi-rigid bases based on cement-stabilized crushed stone have been widely used because of their strong board and high bearing capacity. However, since the semi-rigid material binder is cement, its own temperature shrinkage and dry shrinkage properties can easily cause the base layer to crack when the external temperature and humidity change.

[0003] Asphalt pavement and other diseases caused by reflective cracks in semi-rigid base are inevitable. The road engineering community has been ex...
