Abstract: Road
transport is one of the major components in economic and social development of
a country, especially in developing countries like Pakistan. In Pakistan, 95%
of the total freight movement throughout the country takes place through roads.
Infrastructure development is one of the costlier processes and consumes a lot
of national budget and then to maintain the infrastructure, again a
considerable budget is required. There are various maintenance and
rehabilitation techniques developed so far, with the modernization and new
construction mechanical instruments and machines developed, cold recycling is a
new, environmentally friendly and cost effective rehabilitation technique. The
performance of Recycled mixes is still unknown as the recycled pavements
behaves differently at different temperatures and in different regions of the
world. Laboratory investigation of various stabilizing agents and recycling
agent and amount of RAP and New Aggregates to be used is yet to be analyzed.
Hence this research work is a step forward to investigate the laboratory performance
of fillers and stabilizing agent on the properties of Cold Recycled mixes.
Anionic emulsified bitumen is used as recycling agent and OPC is used as
Stabilizing agent with certain amount of steel slag and marble waste is
used as fillers in place of RAP in this research, and their performance is
compared by Modulus of Resilience, Uniaxial Repeated Load Test (Static Creep)
and Indirect Tensile strength Tests. The mixes containing 100 % RAP shows high
Modulus of Resilience but mixes containing steel slag showed more resistance to
permanent deformation in Uniaxial Repeated Load Strain test.
