Govt Paving Way for Use of Bio-bitumen to Build National Highways: 1 Road Test, 2 Research Projects Underway

The ministry of road transport and highways (MoRTH) has sanctioned two research projects to evaluate bio-bitumen in the laboratory and to assess the long-term performance of pavement constructed with bio-bitumen, union minister Nitin Gadkari said on Wednesday.

Further, a test section was laid on the Shamli-Muzaffarnagar portion of NH-709AD in November 2022 for performance monitoring for a period of three years to assess the suitability of bio-bitumen in road construction, the minister said in the Rajya Sabha.
