Evaluation of Compaction Characteristics and Performance of Warm–Recycled Mix Asphalt

Abstract:

Warm-Recycled Mix Asphalt (WRMA) is a new type mixture that can not only reduces the mixing temperature and exhausting gas emissions but also includes some waste materials (Reclaimed Asphalt Pavement, RAP).The compaction characteristics of WRMA were tested, while the compaction temperatures were 140°C, 130°C, 120°C, 110°C, 100°C and the RAP contents were 0%, 15%, 30%, 45%, and 60%, respectively. The compaction temperature for each WRMA was recommended according to the test results. Furthermore, this paper also evaluated the performances of each WRMA.
