MECHANICAL PROPERTIES OF GRANULAR MATERIALS USED IN PAVEMENT FOUNDATIONS

PROPRIETES MECANIQUES DES MATERIAUX GRANULAIRES DE FONDATIONS ROUTIERES

1. TO MEASURE THE STRESS DISTRIBUTION AT THE LEVEL OF AN ARTIFICIAL SOIL SUPPORTING VARIOUS MULTICOURSE STRUCTURES COMPRISING ONE OR SEVERAL GRANULAR LAYERS AND SUBJECTED TO SURFACE LOADING BY MEANS OF A SINGLE WHEEL OR TWO DUAL WHEELS. 2. TO DETERMINE EXPERIMENTALLY (TRIAXIAL TEST) THE LAWS WHICH GOVERN CHANGES IN THE PERMANENT DEFORMATION OF LARGE GRANULAR SAMPLES SUBJECTED TO REPETITIVE LOADING. THIS RESEARCH PROJECT SUPERSEDES IRRD RESEARCH PROJECT NO.44710.
