Analyze the Influencing Factors of Reflective Crack in Asphalt Pavement and Research on Improving Anti-crack Performance

Cracking of semi-rigid bases is a worldwide problem. Under the effect of vehicle load, temperature and humidity, it gradually develops into cracks of asphalt pavement. Pavement cracking has become the most typical type of pavement disease in our country. It has seriously affected the durability of pavement. In this paper, this research focuses on fracture generation and development path under load field, temperature field and interlayer contact state. Through the comparing the types of asphalt pavement mixture, cement, as well as the effect of interlayer bonding state on anti-cracking, proposed the anti-cracking measures of energy dissipation layer, material anti-cracking reinforcement, and high viscosity interlayer bonding state. Integrating the anti-cracking technology with the asphalt pavement structure layer, thus greatly improves the durability of the road surface.
