Using Scanning Lasers for Real-Time Pavement Thickness Measurement--Phase I

The goal of this research is to investigate and test a new method that can determine the thickness of the pavement in real time by scanning the surface of the base prior to paving and then scanning the surface after paving. Using a scanning laser to record an elevation map of the pavement and its subbase provides thorough coverage that will assure transportation authorities that the entire pavement surface meets thickness requirements.
