The Union Government has formulated a strategy for use of natural rubber in roads as recommended by experts.
The use of natural rubber modified bitumen has been specified by the Ministry of Road Transport & Highways for binder courses and wearing courses laid on National Highways.
The Central Road Research Institute (CRRI) has tested the technology for use of modified bitumen including natural rubber modified bitumen in construction and maintenance of roads under Ministry’s sponsored research scheme.
Accordingly to the findings of the study, natural rubber modified bitumen improves the durability of roads by reducing susceptibility towards temperature variations and improving the desirable properties of bitumen thereby giving overall better performance.
As per the policy of the Ministry of Road Transport & Highways, the modified bitumen can be used for the entire surfacing of the National Highways.
