Measurement and Characterization of Asphalt Pavement Surface Macrotexture Using Three Dimensional Laser Scanning Technology



Pavement macrotexture plays a critical role in highway users' safety. It is also closely related to tire-pavement interaction noise. In recent years, continuous effort has been made toward three-dimensional macrotexture measurement in the field to accommodate pavement management. This study presents a newly developed macrotexture measuring system with 3D laser scanning technology. The underlying system demonstrates a series of desirable properties including: (1) 3D surface feature, (2) high speed data collection, (3) large sampling capacity, (4) high resolution and accuracy, and (5) ease of operation. Based on data collected on a real-world asphalt pavement by the system, it is demonstrated that the existing pavement macrotexture evaluation indexes are extended from 2D to 3D. By comparison, it is shown that the 3D indexes are able to characterize pavement macrotexture in a more comprehensive and realistic manner. The correlation among the 3D indexes is also evaluated, which provides pavement researchers and engineers more flexibility in selecting relevant indexes in macrotexture property evaluation.
