Development of RAP Usage Strategies

Because reclaimed asphalt pavement (RAP) can improve the sustainability of road construction and long-term pavement durability, many transportation agencies are expanding its use. Compared to traditional forms of asphalt, RAP consumes less energy, uses less virgin binder, reduces quarrying, lowers costs, and can be more resilient. Agencies — including Kentucky Transportation Cabinet (KYTC) — must address several issues to ensure RAP performs adequately. These include RAP quality, stockpile management and handling, evaluation of polish resistant aggregate content, accounting for RAP contributions in mixes, and impacts on performance testing.
