Abstract The mechanical behavior and the influence of compaction banding on hydraulic properties in soft porous rocks were studied. tested rock was Calcarenite Tuffeau de Maastricht. In frame experimental investigations, triaxial oedometric tests conducted under dry drained conditions. results demonstrated that is forming discrete bands high confining stresses steep angle shear low stresses. Pe...

A typical flexible pavement structure consists of the surface, base, sub-base and subgrade soil. The loading traffic is transferred from the top layer with higher stiffness to the layer below with less stiffness. Under normal traffic loading, the behaviour of flexible pavement is very complex and can be predicted by using the repeated load triaxial test equipment in the laboratory. However, the...

For several years, the bituminous laboratory of the Joint High­ way Research Project has been concerned with the testing of bitu­ minous-aggregate mixtures and with the development of knowledge that would lead to an understanding of the properties of bituminous mixtures as satisfactory paving materials. At the Thirty-Eighth Annual Road School, a paper entitled, “Role of the Laboratory in the De...
