TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 402: Construction Manager-at-Risk Project Delivery for Highway Programs explores current methods in which state departments of transportation and other public engineering agencies are applying construction manager-at-risk (CMR) project delivery to their construction projects.
CMR project delivery is an integrated team approach to the planning, design, and construction of a highway project, to help control schedule and budget, and to help ensure quality for the project owner. The team consists of the owner; the des
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
