• Abstract:
  By the year 2005, the use of chlorinated solvents is to be eliminated. Faced with this eventuality, VDOT formed a task force to look at alternatives for the acceptance of asphalt mixes. One alternative is to use biodegradable solvents in the extraction tests. Although this alternative is being examined, there are some disadvantages to using these solvents, among which are the equipment needed and time required for testing. The study discussed here examines an alternative procedure that uses a nuclear asphalt content gauge for the determination of asphalt content and cold feed aggregate gradations for aggregate monitoring.
