Imphal, December 06 2021: In contrast to conventional method of road construction, Bhartia Infra Projects Limited (BIPL) is constructing a road from Shingao to Tuivai using a German technology known as Soil Stabilisation method for first time in the state.

The road, which is part of National Highway 102B, is being constructed by BIPL under Package 2B of National Highways and Infrastructure Development (NHIDCL) .

A BIPL engineer revealed that in the earlier method, road construction began with levelling of hill and compression of soil for sub-grade formation which was followed by granular sub base (GSB), laying of (WBM) and Dense Bituminous Macadam (DBM).

But in this German technology, the processes of GSB, WBM and DBM is totally left out and the road is laid out by forming of sub-grade followed by adding of water, cement and chemical compounds formed from locally available materials.

This soil stabilisation process binds soil of the road with two times more force then conventional method.

This technology has been approved by the Union Ministry of Road Transport & Highways and Indian Red Cross.

Soil Stabilisation technology is more environment friendly then earlier methods.

This type of road construction does not require stones that were used in the processes of GSB and WBM.

Using this technology, a double lane road with a width of 7.5 metres can be constructed at the rate of 500 metres per day.

This method of road construction takes far less time than the conventional method.

A road constructed with Soil Stabilisation method will last for 10 years without requirement for any maintenance, the engineer said.
