TRB’s National Cooperative Highway Research Program (NCHRP) Report 634: Texturing of Concrete Pavements explores a recommended process for determining the type of concrete pavement texture that may be used for a specific highway project. The process considers the effects of texture type on friction and noise characteristics.

Appendixes A through F contained in the research agency’s final report are available online. The appendixes provide detailed information on the literature review, test results, and data analysis, as well as a sample specification for texture.
