Assessing laser profilers for measurement of pavement smoothness in Florida

The Florida Department of Transportation's (FDOT) present procedure requires the use of a 15-ft rolling straightedge and a California-type profilograph for acceptance purposes of the final surface finish on asphalt and Portland cement concrete (PCC) pavements, respectively. Testing using such devices is slow, tedious, and labor intensive. Consequently, Florida intends to automate its process of ride acceptance. Therefore, it initiated a field study to assess the feasibility of implementing the use of high speed and lightweight profilers to quantify the ride quality on asphalt and concrete pavements, respectively. The intent was to evaluate their respective level of accuracy, repeatability, and reproducibility since the project-level end use of the data requires higher measurement accuracy and precision. In addition the effects of testing speed gradients on smoothness measurements were also addressed. This paper presents a description of the testing program, the data collection effort as well as the subsequent analyses and findings.
