Bituminous mixtures - Test methods - Part 26: Stiffness
Abstract
This document specifies the methods for characterizing the fatigue of bituminous mixtures using alternative tests, including bending tests and direct and indirect tensile tests. The tests are performed on compacted bituminous material under a sinusoidal loading or other controlled loading, using different types of specimens and supports. The procedure is used: a) to rank bituminous mixtures on the basis of resistance to fatigue; b) as a guide to relative performance in the pavement; c) to obtain data for estimating the structural behaviour of the road; and d) to judge test data according to specifications for bituminous mixtures. Because this document does not impose a particular type of testing device, the precise choice of the test conditions depends on the possibilities and the working range of the device used.
