Abstract
Nowadays recycling is one of the most advance and interesting technique for the rehabilitation of
road pavements. In recent years the increased interest in this process, has led to the development of
various alternative methods for the recovery and the reuse of road bituminous materials. Cold
recycling allows the recovery of bituminous material from an existing pavement without the addition
of heat, whilst ensuring the strength of high quality bound base layers. Resilient behavior, rutting
resistance and moisture susceptibility of five different cold recycled asphalt mixes have been
investigated using UTM-5P. RAP was used as controlled mix to compare with four other mixes having
variable binding material types and percentages. Mixes were evaluated at 40 °C and 50 °C under
varying loading conditions of 150 ms and 450 ms. Resilient modulus decreases with increase in type
and time of loading for all mixes. Both emulsified bitumen with cement and 100% RAP, and 100%
RAP performed excellently during Indirect Tensile Strength (ITS). Foam and emulsified bitumen, steel
slag and marble waste were used as binders. Cold recycled asphalt mixes can be successfully used as
stabilized base course.
