The Audit Report for the year ending March is divided into two volumes viz. Volume I of the Report comprise five chapters containing audit findings related to three departments viz. The Engineering department of Indian Railways is responsible for maintenance of all fixed assets of Indian Railways such as Tracks, Bridges, Buildings, Roads, Water supply, in addition to construction of new assets such as new lines, gauge conversion, doubling and other expansion and developmental works.

Relationship was determined between particle breakage according to standardized and unique non-standardized laboratory test methods. To give a train a good ride, the track alignment must be set to within a millimeter of the design. In this regard, bitumen stabilisation, while reducing settlement and hence the number of interventions, provided a higher shear strength due to the cohesion component, which reduced the abrasion between particles and therefore the production of fines, as can be noted from both BSB series. The required time interval of ballast cleaning can be determined, too. It means that the researchers search the superstructure type s with the lowest LCC related to many, A new laboratory test procedure was developed to be able to evaluate railway ballast particle degradation using dynamic fatigue test. There are several major highway and railway bridges, and many small to medium bridges.
