Mobile Bridge Inspection Unit (MBIU)

The Mobile Bridge Inspection Unit (referred as MBIU) is an Electro-mechanically driven Articulated Structure mounted on a vehicle (a truck) as an aid towards proper inspection of bridges or similar infrastructures by enabling an inspection team of 3-4 persons carrying instruments access to the underside of bridge decks over flowing rivers or gorges.
Utilization of Municipal Solid Waste (MSW) in Road embankment

About 65-75% of segregated Municipal Solid Wastes can be used for embankment construction.Leachate studies indicate that MSW is a non hazardous material as concentration of heavy metals is within the permissible limit.Typical design cross sections have been arrived for 3m and 5m height MSW embankment.
Patch Fill-Pothole Repair Solution for Bituminous Roads

Patch-fill solution is useful for faster filling of potholes in bituminous roads without causing any environmental pollution and hindrance to roads users. Potholes filled by Path-fill shall be long lasting.
India hails success of first ‘steel-slag road’

A stretch of six-lane road experimentally paved with slag from steel-making in India has been shown to weather the beating from thousands of heavy trucks even though the surface is 30% shallower than that of roads paved with natural aggregates. Slag is made up of impurities melted out of the ore during the steel-making process. The trial, guided by the Central Road Research Institute (CSIR-CRRI) and sponsored by ArcelorMittal Nippon Steel (AM/NS).
