Effect of Addition of Plastic in Bituminous Mixes Prepared with Modified Bitumen

Abstract

The present study deal with the utilization of PET waste in Bituminous Concrete prepared with modified bitumen. The detailed analysis will be carried out to assess the physical and strength characteristic of prepared BC mix as per the Indian Standards. Modified bitumen used is CRMB -55 which is a binder obtained from the recycling of rubber tyre. Modified bitumen is temperature susceptible and also increases the fatigue life of pavement under the heavy traffic load. The study involved in the evaluation of more than one modification in bituminous mixes such as CRMB -55 is itself modified binder while modification has been done in the aggregate blend by addition of plastic. However, a combination has not yet been tried. The Marshall Stability test was performed to assess strength characteristics. The Marshall Stability values increase with the amount of PET and maximum stability was obtained at 6% by weight of the binder. The considerable increment was observed in Stability value with PET 6% dosage as 18.99%.
