ASTM E2133-03 (R2020) PDF Download

ASTM E2133-03 (R2020) is a standard test method that provides procedures for collecting elevation and distance data of longitudinal and transverse profiles on a traveled surface. The results of this test are primarily used to evaluate the roughness of traveled surfaces, investigate the effect of different construction methods on pavement surface roughness, investigate pavement surface curvature and deflection of structural members, identify locations in need of corrective grinding, and measure rut depth.

The test method involves using a rolling inclinometer that travels at walking speed to measure the transverse and longitudinal surface profiles of paved road, bridge, and airport surfaces. The inclinometer collects data on the elevation and distance of the profiles, which can be used to assess the roughness of the surface. The collected data can also be used to determine the need for corrective grinding and evaluate the effectiveness of corrective grinding.

It is important to note that the timeliness of the test in relation to the date of the surface's installation is critical when evaluating compliance with roughness specifications. For contractor quality control purposes, it may be desirable to gather profile data within 72 hours after pavement installation, as portland cement concrete surfaces can change shape due to thermal and moisture gradients.
