Abstract: As with the passage of time, natural resources become extinct. Different recycling techniques are being developed for the use of recycled materials. Reclaimed asphalt pavement materials (RAP) have been used in cold in place recycled pavements worldwide from early nineties. The performance of CIPR technique varies in different zones of the world and up till now its mix design is under development stage. This research work is done to evaluate the behavior of CIPR mixes using different additives keeping in view the local conditions of Pakistan. For this purpose resilient modulus and static creep test has been performed on Marshall Samples of CIPR mixes using UTM-5P with foam and emulsified bitumen as additives. It was concluded that samples with foam bitumen showed more structural adequacy as compare to emulsified bitumen samples at various temperatures and loading frequencies according to Pakistani traffic conditions.
