During its 1972 session, the General Assembly of Virginia enacted Senate Bill 104, which authorizes the breath test, as well as the blood test used previously, as a proper chemical test to determine the alcoholic content of the blood. Any person arrested in Virginia after January 1, 1973 for suspicion of driving while intoxicated may elect to have

In southwest Louisiana, some surface silts (up to 3 feet deep) collapse under load after moisture is added. These soils were indistinguishable from nearby normal silts through routine tests. The deposits occur as low, gently-sloping ridges. Very similar collapsible soils were found in the well-known pimple mounds of the area. In the stable silts, v

For pavement design purposes, the Virginia Department of Highways uses the AASHO method of determining the 18-kip equivalent single axle load (EWL-18). The evaluation of the EWL-18 is based on on-location truck axle weight studies that usually are carried on for one day only. This method is expensive and time consuming. Because of the expense and t
