BITUMEN MODIFIERS-AN INTRODUCTION
Requirement of better binding capacity bitumen to withstand current road traffic and air traffic is need of
hour. Bitumen modification is not new; it was started as early as 18th century. But recent additions of
polymer modified bitumen and crumb rubber modified bitumen has shown a new ray of hope for
sustainable road. But both have some storage stability issues. Current work shows a brief account of
different methodologies used for bitumen modification.
