Bihar, Tripura may adopt BMC’s UTWT method for pothole-free, durable roads

The Brihanmumbai Municipal Corporation’s (BMC) Ultra-Thin White-Topping (UTWT) method for pothole-free and durable roads is likely to be used in Bihar and Tripura for road construction under Pradhanmantri Gram Sadak Yojana (PMGSY). In an interaction organised by National Rural Infrastructure Development Agency (NRIDA) on Monday, the governments of the two states said they will consider the UTWT method for further road works.

The UTWT method was developed by BMC road engineer Vishal Thombare in 2010 during his Phd research at Indian Institute of Technology (IIT-Mumbai). Thombare, who is now an executive engineer in Roads and Traffic department, has completed his Phd in ‘Analysis, Evaluation and Construction of Thin White Topping for Rehabilitation of Flexible Pavements’.
