The average thickness of bituminous binder – criterion for the analysis of performance behavior of hot rolled road asphalt pavements

Abstract

Although the average thickness of the bituminous binder does not represent a criterion for the design of the composition of the asphalt mixtures, it could be useful for the analysis of the premature distressed observed in the asphalt pavements. This paper intends to present the method of calculation of this parameter and suggests its correlation with the performance of the asphalt pavements, expressed in terms of type and extension in time of the specific distress phenomena. These correlations could be then recorded in a road data base, in order to be use, later on, for such analyses.
