Abstract: The typical pavement structure models of the low county roads are built in the test slots.The actual work condition of the pavement is imitated by acquiring a large quantity of loading and the breakage pocess in experiments.Th e related function parameters,such as the stress stain mt depth，are measured by the experiments and mseareh testifyings in the test slots in order to establish whether the four kinds of pavement structure Can satisfy the cowgirl transportation level requ ests or not.Th e pavement structure guidebook that are established by the actual roads build experiments is reasonable on the technique.
