Abstract

The pavement response in mechanistic-empirical design of asphalt pavements is largely affected by the resilient moduli of pavement layers. Thus, an accurate determination of the resilient modulus is an imperative task in order to predict the pavement response with a reasonable accuracy. Factors affecting the resilient modulus of hot mix asphalt were thoroughly investigated in this paper. A fractional factorial design of experiment was carried out to investigate seven factors each factor was studied at two levels. These factors are: the maximum nominal aggregate size, specimen diameter and thickness, the load pulse form and duration, the compaction method and the strain level. This study attempts to examine how the different factors interrelate to affect the resilient modulus. (a) For the covering entry of this conference, please see ITRD abstract no. 0612AR242E.
