Abstract: To solve the problem of the semi rigid base course, which was easily to produce reflection cracks and set out the pavement structure which was suitable for Liaoning area.This paper taked the example of a municipal road in Fushun city as the research object, using temperature shrinkage test and finite difference numerical software FLAC3D, and researching and analyzing on the mechanical properties of asphalt concreted pavement under the action of temperature load then paving the test road.The results show that the suppression of reflection cracking effect of graded broken stone is better.The conclusion can provide reference for road design, construction and management of asphalt pavement rut engineering personnel, which is a certain social and economic benefits.
