Abstract

Pavement recycling technology, as an alternative technology in road pavement construction and maintenance, is continuously developed. The aim of this study is to modify recycled material by adding a polymer that is able to improvethe physical properties and performance of asphalt and recyled mixture. Asphalt mixture used in this study was Aspahlat Concrete-Wearing Course (AC-WC) containing Reclaimed Asphalt Pavement (RAP), fresh materials, asphalt Pen 60/70, and SBS polymer. The proportion of RAP used was 20% and 30% of the total weight of the mixture. For each RAP variation, asphalt Pen 60/70 was mixed with 0%, 2.5%, and 5% of SBS polymer. Fatigue performance of mixture was, then, measured using 4-Point Bending Test Apparatus. The results show that RAP asphalt has lower penetration and higher viscosity values. Fatigue test shows that the increase in the proportion of RAP will improve the fatigue resistance of the mixture.Keyword: Reclaimed Asphalt Pavement, SBS Polymer, fatigue performance.

Abstract

Subgrade is an important part in road pavement construction, which serves as the foundation and must have the ability to bear the traffic load applying on the surface of the pavement. This study examined changes in the carrying capacity of soft soil after stabilization process using asphalt emulsion. The results of this study indicate that the stabilization process using asphalt emulsion can lower the Plasticity Index and increase the dry density and strength of the soil.Keywords: subgrade, stabilization, asphalt emulsion, Plasticity Index, dry density, soil strength.
