Develop Laser Thickness-Measuring Device for Thermoplastic Pavement Marking Material: Summary Report

Based in the research results in Projects 0-4282, lightweight in compact size pushcart and vehicle-mount laser thickness-measurement devices have been successfully developed. The Length, Width, and Height, which are 42.5 inches, 29 inches, and 47 inches in the old pushcart version, respectively. The weight is only half of the old version. The new pushcart is easy to be handled by one person to do routine project monitoring practice. To increase the TPMM thickness measurement speed, a prototype of vehicle-mount laser thickness measurement system is also developed. Two synchronized laser devices are installed onto a golf cart. The tape thickness is obtained by processing the output signals from the two laser devices.
