Polymer Modified Asphalt Guideline. Phase 1. New Mexico Modified Asphalt Database
Six paving grade asphalt cements were combined with eleven polymers at low and high levels of concentration. Laboratory testing was conducted before and after rolling thin film circulating oven (RTFCO) aging to measure the effect of heat and air on the physical properties of binders. Two full-scale field tests containing two of the polymer modified asphalts were constructed to determine if differences in construction practice were necessary when fabricating asphalt concrete with polymer modified asphalt and to provide baseline information regarding field performance of certain of the modified asphalts contained in the database. Laboratory tests indicate that rolling thin film oven aging had less effect on hardening of polymer modified binders tested than corresponding control asphalts. Conventional kinematic viscosity tests for determination of field mixing and compaction temperatures appear to be misleading for certain polymer modified asphalt binders. The kinematic viscosity results indicated significantly higher mixing and compaction temperatures than were necessary during full-scale tests.
