Abstract:In the first year of this project, a comprehensive review was made of the available models for
predicting the major distresses in flexible pavements, including cracking of asphalt layers and chemically
bound layers, permanent deformation of asphalt layers, and permanent deformation of granular base and
subgrade layers. In conducting these reviews, the latest models under consideration in both national efforts
and various state development efforts were reviewed. The models identified for each of the major distresses
are described in this report. Additionally, the associated laboratory test procedures, which can be used to
provide TxDOT with the material properties needed as inputs to both the pavement response and
performance prediction models, were also identified and discussed. Finally, a detailed laboratory testing
plan was proposed for Year 2 study.
