List the given and required. Box the final answer.
The lab methods discussed in class are not the only means of measuring specific gravity- one can also measure the volume of water displaced directly. Suppose you have a sample of sand that displaces 251 cm³ in the SSD state. The sample has an SSD weight of 618 g and an oven dry weight of 599 g. Calculate the bulk specific gravity (SSD), bulk specific gravity, apparent specific gravity, and absorption (dry) of the material.

A transportation agency is planning a pavement roughness data collection program to monitor statewide pavement performance. Assuming that 10 percent of change in roughness should be detectable at 95% confidence level, how many 1-mile pavement segments should be included in the annual condition survey? There are 20,000 center-line miles of pavement in total.
