A Precast Road Panel Structure for Heavy Vehicles

Abstract:

A composite precast road panel structure system suitable for heavy vehicles is put forward, which combined by two layers of composite stagger-jointed road panel. Experiment research are adopted to study the proposed road panel structure and common road panel structure respectively. In order to research the proposed road panel structure performance under heavy vehicles, five different cases are studied in experiment each which different vehicle routes. The test results show that the proposed one can reduce 24.2% to 46.4% ( an average of 35% ) of the subgrade stress in five cases so as to reduce the subgrade damage under driving heavy traffic.
