Study on the Properties of Sand Sheet Asphalt Mixture Using Old Road Pavement Milling and Asphalt Emulsion

Abstract:

This paper describes experiments on sand sheet (SS) asphalt mixture utilizing reclaimed asphalt pavement (RAP) from road milling of old road pavement. Natural aggregate was added to adjust the aggregate grading to closely meet specification. The mixture was bound with asphalt emulsion cationic rapid setting (CRS), type CRS-1. The SS mix was produced by hotmix procedure, compacted with 2x50 Marshall blows. Sand sheet asphalt mixture is dedicated for low to medium trafficked road pavement. The asphalt content of the RAP was extracted, and contained 5.29%. The performance of the SS mix was compared to asphalt concrete wearing course (AC-WC), using natural aggregate and 50pen asphalt, compacted at standard of 2x75 Marshall blows. At optimum asphalt content, the Marshall properties of both mixture met specification in Indonesia. The creep performance of both mixture was closely comparable, although the SS mix was compacted at lower compaction level. According to its dynamic creep slope, the SS mix is suitable for pavement with medium traffic load at temperature > 30 o or suitable for road with heavy traffic at temperature < 30 oC. The fatigue performance of SS mix was far better than the AC-WC mix, as the SS mix contain higher asphalt content and of finer aggregate grading.
