Studies on Performance Characteristics of Warm Recycled Asphalt Mixes

Abstract

Recycling of asphalt pavement materials and incorporation of warm mix asphalt (WMA) technology are the two methods adopted for recycling existing pavements and also to reduce carbon emission. The quality of reclaimed asphalt pavement (RAP) materials depends on its age, as the material rheology plays the prominent role. Studies were carried out on two different aged RAP materials viz, 8 years and 12 years using VG30 binder. The RAP materials were blended at varying proportions of 10, 20 and 30% for SMA mixes. Zycotherm is used as warm mix additive. Recovered binder and VG 30 with warm mix additive were characterized by complex modulus test. Mix design was carried out by Marshall method to determine stability and optimum binder content (OBC). The RAP Warm SMA mixes were tested for its indirect tensile strength (ITS) and rutting resistance. The binder rutting properties G*/Sin improved with increase in RAP content and fatigue parameter G*Sin decreased with increase in RAP age and its percentage. Based on performance tests conducted, it is observed that 12 years aged RAP indicated better resistance to rutting when compared to 8 years RAP binder. Similarly mixes prepared using WMA additives indicated better resistance to moisture for both 8 and 12 years aged RAP mix.
