Abstract

Abstract: The paper compares the bending and the cleavage properties of semi-rigid basecourse material. Semi-rigid material is in a state of two-direction stress as it was split ted, and the practical basecourse material is in three under the traffic loads. The conclusion is given that the cleavage fitague testing method is more reasonale than the bending fitague testing method for determining the fitague properties of semi-rigid material.

Key words: semi-rigid basecourse, fatigue
