DESIGN OF ASPHALT PAVEMENTS USING LATERITIC SOILS IN BRAZIL. SIXTH INTERNATIONAL CONFERENCE, STRUCTURAL DESIGN OF ASPHALT PAVEMENTS, VOLUME I, PROCEEDINGS, UNIVERSITY OF MICHIGAN, JULY 13-17, 1987, ANN ARBOR, MICHIGAN

New developments of overlay design for flexible pavements composed of granular layers and asphalt concrete surfacing of main highways are presented. They were confirmed through measurements on experimental sections before and after overlaying conducted by the Brazilian Road Research Institute (Instituto de Pesquisas Rodoviarias). Resiliency studies of lateritic fine sands used in low cost pavements have revealed new models of behavior concerning resilient moduli against stresses which are reported herein. Progress on tropical soil classification for pavement design is presented. It distinguishes the lateritic behavior from the non-lateritic behavior, using new identification testing procedures. The fundamental principles of pavement mechanics according to engineering experience and applied research developed in Brazil are enunciated. They are seemingly of interest to other tropical regions.
