Abstract
Based on cost effectiveness, environmental impact, energy savings, and shortages of quality materials, reclaimed asphalt pavement (RAP) used for pavement construction does not only reduce aggregate need, but it also solves the problem of RAP disposal. Thus, the technology of cold mix recycling for pavement sub-base and base is introduced and tested in laboratory. The test results show that the recycled cold mix is a candidate material for pavement sub-base and base layer use. However, cold-mix emulsion asphalt used for recycling must be designed properly to ensure reliable performance. The unique features of recycled cold mixes are time temperature effects.
