- Abstract:
-
In order to improve the problems of insufficient design life and short actual service life of existing pavement, starting from the research of long-life pavement, the definition and design requirements of long-life pavement were discussed, combined with the PCC+AC long-life pavement structure relying on the project, using the theory of finite element and pavement elastic layered system, the mechanical model of PCC+AC long-life pavement was analyzed and determined, the load stress and temperature stress at the bottom of the PCC plate were calculated and analyzed, and the pavement service life was estimated, and the theoretical service life reached more than 40 years. Its life is in line with the design idea of long-life pavement. Finally, in order to enhance the adhesion between cement concrete and asphalt concrete, the bare time and technical requirements of cement concrete slab are studied.
