CHARACTERIZATION AND STRUCTURAL ASSESSMENT OF BOUND MATERIALS FOR FLEXIBLE ROAD STRUCTURES. SIXTH INTERNATIONAL CONFERENCE, STRUCTURAL DESIGN OF ASPHALT PAVEMENTS, VOLUME I, PROCEEDINGS, UNIVERSITY OF MICHIGAN, JULY 13-17, 1987, ANN ARBOR, MICHIGAN

In order to generalize pavement design and management systems, prediction methods have been developed at the Belgian Road Research Centre. These methods allow the assessment of the dynamic modulus, the fatigue law of bituminous mixes on the basis of a limited number of input data describing the mix volumic composition and binder characteristics. The general formulas proposed were obtained after a statistical analysis of a large variety of compositions. The properties measured on mixes containing modified bitumens have been used to illustrate a procedure for the determination of equivalent thicknesses. A structural factor allowing the generalization of design methods can be derived in this way. A stress analysis procedure based on the method of finite differences was used for the study of the stress distribution in cracked road structures or in the vicinity of buried joints.
