Abstract

Warm mix asphalt (WMA) technologies that use foaming most commonly used due to their cost effectiveness. This technologies allow the reducing of asphalt binder temperature by adding additives foaming chemical. Civil engineering infrastructure materials can significantly contribute to the sustainability movement through the use of recycled materials and more environmentally friendly production processes. Recycling has been defined as a method by which reclaimed asphalt pavement (RAP) is combined with new aggregate and bitumen or recycling agent to produce hot mix asphalt and obtained by pavement milling with rotary drum cold milling machine or from a ripping/crushing operation. This paper described the feasibility of utilizing Reclaimed Asphalt Pavement (RAP) in Warm Mix Asphalt using foaming technology. Despite the promising performance in comparison with HMA, this technology has not yet gained acceptance in asphalt industry. In order to reach widespread implementation it is necessary to prove that WMA has the same or better characteristics and long term performance as HMA. Besides, it discover whether by the use of foamed warm asphlat additives are possible to reduce the high temperature whilst slower aging of the modified binders and will helps to give better understanding on environmental effect of both human and materials.
