Abstract

The invention discloses a waterproof, anti-skid, high-toughness and anti-cracking pavement joint strip. The pavement joint strip comprises an anti-skid wearing layer, a fiber anti-cracking layer, an asphalt bonding layer and an anti-sticking film layer from top to bottom. The pavement joint strip has good anti-skid, wear-resistant, crack-resistant and water-tight effects, can be widely applied toasphalt pavement crack treatment, effectively inhibits expansion of asphalt pavement cracks and water seepage of the cracks, and is a novel road material which accurately and quickly solves the problem of structural damage caused by cracking of the asphalt pavement and effectively improves the driving comfort.

Description

technical field [0001] The invention belongs to the technical field of highway engineering, and in particular relates to a seam tape for pavement with waterproof, anti-slip, high toughness and crack resistance. Background technique [0002] Cracks are the most common hazard of asphalt pavement and one of the main causes of pavement structural damage. The initial stage of crack formation has little impact on the performance of asphalt pavement, but with the influence of external factors such as driving load, temperature shrinkage, frost heave, rainwater infiltration, etc., the crack will continue to expand, and the specific performance is: the crack width is enlarged, the crack length is extended, As the cracks become deeper, they may even cause structural damage to the asphalt pavement, thereby affecting the performance of the asphalt pavement. Therefore, it is very necessary to effectively deal with cracks in the early stage of formation. [0003] Sticking seam tape on cr...
