Scraper Production Estimating You are using 631E Scrapers for an earthmoving project (Scraper specifications are found in Table 8.1 and performance charts are found in Figures 8.10 and 8.11).

Using the Scraper Production Estimating Format, analyze the scraper production, and answer the questions that follow (be sure to fill in ALL highlighted cells). Material is a sandy clay (dry earth), weighing 2850 Ibs/bcy. The Material will swell 25% when excavated from its Bank state. A well maintained haul road has a rolling resistance of 40 lbs/tn.
