THE CIRCULAR TEST TRACK OF THE "LABORATOIRE CENTRAL DES PONTS ET CHAUSSEES" (L.C.P.C.) NANTES - FIRST RESULTS. SIXTH INTERNATIONAL CONFERENCE, STRUCTURAL DESIGN OF ASPHALT PAVEMENTS, VOLUME I, PROCEEDINGS, UNIVERSITY OF MICHIGAN, JULY 13-17, 1987, ANN ARBOR, MICHIGAN

The circular test track of the Laboratoire Central des Ponts et Chaussees has been in service for two years. The properties and performance of this sophisticated machine are remarkable, especially as regards the applied load. The first part of the article gives a brief description of the installation and of the measuring apparatus and how it is used. The second part of the article deals with the role of the circular test track in highway research and with the first results obtained on asphaltic pavements. These results concern the factors of equivalence among axles, which vary both with the type of pavement and with the type of damage considered, the representation of flexible pavements by mathematical models, the laws governing rutting and cracking, and the deadlines for repair work in view of the speed of evolution of the damage once the process has begun.
