Evaluation of Appropriate Performance Grade Bitumen for Road Construction According to Indian Climate Change Scenario
It is well known that bituminous binders play an important role in the performance of the pavements and therefore selection of quality and quantity of binder is crucial. For any location, pavement temperature and expected traffic are the general parameters considered for choosing type of binder and mix design for amount of binder. Neat normal, polymer, crumb rubber modified binders are being currently used in India to build high volume roads and these binders are classified based on the parameters such as (i) viscosity at 60 °C (ii) penetration value and (iii) softening point value of the binders, respectively. It is argued that due to climate change, the binders to be selected may be different from those commonly selected at the design stage of the infrastructure, since likely higher temperature determine more demanding constraints. It is therefore necessary to initiate the development of performance-based specifications in India. This work explores the influence of climate changes on the proper selection of bitumen grade for pavement construction purposes, according to the Performance Grade (PG) defined in the SUPERPAVE specifications. The present study has attempted to classify commercially available Viscosity Grade binders from different sources for performance through a well-conceived mapping system.
