This test method describes a procedure for determining the average depth of pavement surface macrotexture by measuring the profile curve of a surface and calculating texture depth from this profile. The technique is designed to p provide an average depth value of only the pavement macrotexture and is considered insensitive to pavement microtexture and unevenness characteristics. The objective of this standard is to make available an internationally accepted procedure for determination of pavement surface texture depth which is an alternative to the traditionally used volumetric patch technique.
