The design method for secondary roads and that for subdivision roads are based on AASHO Road Test Results and Virginia's design experience. For flexible pavements, the methods are divided into two parts: (1) the evaluation of the soil support value of the subgrade, the thickness equivalences of the paving materials, and the traffic in terms of vehi

Over the last three years the Virginia Highway Research Council has directed a research effort toward improving the method of determining the moisture content of soils with a nuclear gage. The first task in this research was the determination of the correct moisture calibration curve for the nuclear gages being used (Troxler Models 227 and 2401). F

It was found that valid predictions of the use of containers were extremely difficult to make because of the lack of reliable data. Further, during the time of the study, the local ports negotiated for international consolidation, the dollar was devalued, and relations with foreign countries and the nation's export policies were changed. Because th

Sedimentation in ponds is an important problem for several reasons. The depletion of pond storage capacity is of major concern. Sediments also may degrade the water by burying bottom-dwelling plants and animals and may carry harmful chemicals which promote entrophication and kill aquatic life.
