Analysis of Concrete Bridge Asphalt Pavement's High Temperature Stability

摘要

The asphalt pavement of cement concrete bridge belongs to thin structure, its high temperature stability is an important indicator. Using self-made heating system, through test on full scale linear track, conduct on-site rutting survey, and supplemented by the identification of drill core samples and laboratory test of pavement's rutting, research on asphalt pavement's high temperature stability on the bridge. The research results not only provide a strong basis to the concrete bridge asphalt pavement mix design, but also provide some reference to similar engineering practice.
