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.
