Question

Two scrapers will deliver to the project 650 LCM per hour of fill material. The rolling width of the roller is 1.2m. 6 passes at 4 km/hr are required to obtain the required density.

The fill material will be placed in 0.3m compacted lifts. Load factor (LF) = 0.8 and shrinkage factor = 0.85.

Assume a 50-min job efficiency, determine the number of rollers required to support the scraper operation.
