Significance and Use
5.1 This test method establishes procedures for collecting elevation and distance data of longitudinal and transverse profiles on a traveled surface.
5.2 Results of this test are used primarily to:
5.2.1 Evaluate the roughness of traveled surfaces, using any of several roughness indices shown in Table 1. Equations required for calculations of various indexes are contained in references shown in Table 1.
5.2.2 Investigate the effect of different construction methods on resulting pavement surface roughness.
5.2.3 Investigate the curvature of (1) pavement surfaces due to curling, and (2) deflection of structural members within bridges and other structures.
5.2.4 Identify the locations in need of corrective grinding.
5.2.5 Measure rut depth using computer simulation in accordance with Test Method E1703/E1703M.
1.1 This test method describes the measurement of transverse and longitudinal surface profiles on paved road, bridge, and airport surfaces using a rolling inclinometer traveling at walking speed.
1.2 It is designed to (1) quantify the roughness of new pavements and bridge decks; (2) Investigate the effect of various construction methods on surface roughness; (3) determine the location for corrective grinding; and (4) evaluate the effect of corrective grinding.
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
