Environmental Effects in Pavement Mix and Structural Design Systems

The objectives of this research are to: (1) validate the latest version Integrated Climate Model (ICM) developed in NCHRP Project 1- 37A with data from the Long Term Pavement Performance Seasonal Monitoring Program; (2) develop practical guidelines for selecting ICM input data sets; (3) verify the estimated period or rate of aging simulated by the current Superpave binder and hot mix asphalt conditioning procedures - AASHTO provisional practices PP1 and PP2 - with data from Long Term Pavement Performance Specific Pavement Studies and other relevant field experiments; and (4) revise the current conditioning procedures as necessary for their use with the materials characterization test and model under development in NCHRP Project 9-19 for the Superpave performance model system.
