CRUMB RUBBER MODIFIED BITUMEN (CRMB)

The Crumb Rubber Modified Bitumen (CRMB) is a blend of CRM with Bitumen in a specified ratio offers sustainable & long lasting roads. This not only helps in saving natural resources but also is a prime example of circular economy.

Advantage of CRMB over plain bitumen

It increases resistance to degradation at high and low temperatures
It maintains its properties during storage, application and in service
It is suitable to withstand all weather conditions in highways, dense traffic roads and more
Roads made with CRMB (Crum Rubber Modified Bitumen) do not oxidise fast and hence, they remain black for a longer period.
CRMB (Crum Rubber Modified Bitumen) has higher softening point, giving more stability to the pavement during hot months.
Much improved Elastic Recovery over 60, giving resistance to fatigue.
Improved resistance to stripping due to water repellent properties.
Lower susceptibility to daily and seasonal temperature variation.
Better age resistance properties.
Much improved Elastic Modules increases load carrying capacity.
Delays oxidization of mixes thus enhanced pavement life.
