Concrete Pavement Reporter E-News, February 2009
The Concrete Pavement Reporter is the e-newsletter of the National Concrete Pavement Technology Center (National CP Tech Center).
New manual on pavement preservation and rehabilitation
This manual accompanies the Concrete Pavement Preservation and Rehabilitation Workshop, providing the most up-to-date information available on the design, construction, and selection of cost-effective concrete pavement preservation strategies.

Expanded second edition of the Guide to Concrete Overlays
- This edition enhances the original material and adds detailed guidelines for several new topics:
- Evaluating existing pavements to determine if they are good candidates for concrete overlays
- Selecting the appropriate overlay system for specific pavement conditions
- Managing concrete overlay construction work zones under traffic
- Accelerating construction of concrete overlays when appropriate

Surface characteristics interim guidelines
The National CP Tech Center has amassed the largest database so far of concrete pavement surface characteristics. The newly released guide How to Reduce Tire-Pavement Noise: Interim Better Practices for Constructing and Texturing Concrete Pavement Surfaces is based on data collected from nearly 1,500 test sections throughout North America and Europe.

Two resources on two-lift concrete paving
In fall 2008, the National CP Tech Center coordinated the first national demonstration project and open house on two-lift concrete paving in Saline County, Kansas.
