Reliable predictions of asphalt materials and pavement performance are important elements in mixture design, mechanistic-empirical performance-related specifications. This paper presents FlexPAVE™, a prediction program. FlexPAVE™ is three-dimensional finite element program that capable moving load analysis under realistic climatic conditions. It utilizes the simplified viscoelastic continuum damage (S-VECD) model to predict fatigue life. S-VECD currently incorporates so-called G R failure...
Thermal cracking is the predominant failure mode for asphalt pavements constructed in regions with severe air temperature drops or significant daily variations. The thermal stress restrained specimen test (TSRST) one of a few tests that can simulate loading field. Conducting TSRSTs time-consuming task; therefore, predictive methodology needed predict fracture mixtures measured by TSRSTs. To this end, paper utilizes dissipated pseudo strain energy (DPSE), which be predicted using simplified...
Abstract Thermal cracking is one of the most prevalent types distress found in asphalt concrete pavement sections. The coefficient thermal contraction (CTC) intrinsic parameter that determines mixtures subjected to temperature drop. Thus, stress and associated damage are greatly affected by CTC mixture. direct measurement a mixture’s reliable at same time cumbersome method for predicting asphaltic mixtures. In this study, Level I analysis, we measured CTCs have wide range properties reported...
