Abstract

Asphalt overlay on existing cement pavement structure design and typical diseases (such as low temperature cracking and fatigue cracking temperature, temperature type of reflective crack) have a strong relationship with temperature; At the same time, vehicle load and temperature stress also produce different effects on asphalt overlay on existing cement pavement. In this paper, through the establishment of three-dimensional finite element model and field test based on the theoretical analysis method, temperature field distribution and influencing factors of asphalt overlay on existing cement pavement were studied. Results showed that different materials and thickness of asphalt overlay on existing cement pavement had weak influence on road surface temperature. The main factor was heat exchange between road surface and the air (namely, solar radiation and air temperature).
