Durable asphalt composition

Abstract

The invention discloses a durable asphalt composition. The durable asphalt composition consists of the following ingredients in parts by weight: 10 to 20 pars of liquid petroleum resin, 5 to 10 parts of styrene, 6 to 12 parts of an emulsifier, 3 to 5 parts of sulfur, 5 to 7 parts of an anti-aging agent, 3 to 8 parts of mixed silane and 4 to 6 parts of aromatic oil. The durable asphalt composition can be widely applied to the road construction and road maintenance and is mainly applied to the dense-graded asphalt mixture, a stress absorption layer, a deck waterproof technology and a synchronous crushed stone seal layer. When the durable asphalt composition is applied to the deck waterproof layer, the durable asphalt composition can be well combined with a functional layer, and the slipping phenomenon of the functional layer can be solved; when the durable asphalt composition is applied to the stress absorption layer, the low-temperature crack resistance of rubber powder can be adequately reflected, and the rising capability of a reflection crack is slowed down; when the durable asphalt composition is applied to the asphalt synchronous crushed stone seal layer, effects of resisting the water and slipping, absorbing the sound and lowering the noise can be realized.

Description

technical field [0001] The invention relates to a road construction material, in particular to a durable asphalt composition resistant to high temperature storage. Background technique [0002] As a continuous pavement, asphalt pavement has the characteristics of comfortable driving and easy maintenance, and has become the main form of pavement. However, asphalt pavement has insufficient high temperature stability, low temperature crack resistance, and water damage resistance, which easily cause rutting, cracks, and potholes. In order to reduce the premature appearance of diseases, modified asphalt materials are mostly used now. At present, SBS modified asphalt is widely used as the modified asphalt material, but this kind of asphalt modifier has the problem of high price, and the modification process is relatively complicated. The addition of waste rubber powder can make the asphalt achieve the effect of modification, and its performance index can reach the standard of SB...
