Analysis of Surface Inertial Profiles Measured on Jointed Portland Cement Pavements


The feasibility of measuring slab curling using high-speed profilers was assessed by the Turner-Fairbank Highway Research Center of the Federal Highway Administration. The primary objectives of the study were to: (1) measure the surface profile of the concrete slabs using state-of-the-art profiling technology, (2) establish a standard procedure to identify warping and curling of the slabs using the measured surface profiles, (3) relate the changes in pavement surface profiles to the change in surface temperature, (4) determine the relationship between changes in pavement surface profile, roughness, premature transverse cracking, and construction condition, and (5) establish a standard procedure to analyze the condition of joints, including rotation and faulting, and determine the relationship between joint condition, and roughness. The paper discusses data mining on a database of 16 000 slabs measured during four time windows in a 24-h period. A visualization of all parameters and samples at all four times of the day show the groups of slabs which have cracked and are likely to crack shown by the divergence from the normal response measured in most slabs.
