Using Scanning Lasers for Real — Time Pavement Thickness Measurement
This paper examines a system that could determine the thickness of the pavement in real time by laser scanning the surface of the subgrade prior to paving, and then scanning the surface after paving. By having this data, the pavement can be evaluated for conformance to project requirements for thickness. This paper also examines existing nondestructive methods of measuring pavement thickness including impact echo and high frequency ultrasound, and presents the advantages of each in relation to a scanning laser based system. Existing 3D imaging techniques are discussed such as shadow moiré, ground penetrating radar, stereo vision, and airborne radar. Laser scanning provides a thorough coverage of the pavement that will assure transportation authorities that the entire pavement surface meets thickness requirements. Other benefits from this technique involve being able to determine concrete yield quantities and possibly smoothness. This sensor will be able to provide real time depth measurements as a profile of the concrete will be generated. Volume of concrete in place will be easily determined using this approach. The system would fit on any paver that can provide position coordinates and may be retrofitted onto a paver by using relative position control.
