Abstract:

This laboratory investigation was instituted to determine the feasibility of increasing the design mixing temperature for hot-mix asphaltic concrete. Based on data obtained from modified thin film oven tests, it appears that the upper design limit could be increased to 300°F without appreciably affecting the durability of the asphalts studied. The data also indicate that softer grade asphalts (120-150 penetration) remain considerably higher in penetration value than harder asphalts (50-60 and 60-70) after the modified thin film test.
