    Abstract

    Recycling of 100 % reclaimed asphalt pavement (RAP) without adding any virgin materials is a challenging task. Most of the present RAP-recycling technology is limited to use the 20 %–30 % RAP as a maximum content for wearing courses of asphalt pavements. The main goal of the existing recycling technology is focused to restore original properties of the straight asphalt pavement mixtures by using rejuvenators. Here, a new technology is introduced to use 100 % RAP-recycling by adding a specially developed polymer-modifier. The hot mix asphalt design is used to figure out the content of the modifier. Quality of the new recycled mixtures is excellent such that their properties are superior over the virgin straight asphalt mixtures. Excellent quality, maximum use of RAP, simple process, and competitive price will make this technology very attractive.
