Supplementary Notes Final- 14. Sponsoring Agency Code Research performed in cooperation with DOT, FHWA. Study Title: "Hardening of Asphalt". 16. Abstract An evaluation of the relation between asphalt hardening, thermal forces and pavement cracking in Texas is made. Thermally induced cracking of hardened pavements is found to be a potential failure mechanism in West and Central Texas. Factors affecting asphalt hardening susceptibility are studied. The form of a generalized model for predicting hardening of asphalt as a function of time is proposed. Recommendations regarding the type of asphalt to be used in West and Central Texas are made. 17. Key Words 18. Distribution Statement Asphalt hardening, thermal cracking, asphalt content, compactive effort, special additives. No Restrictions.
