The National Concrete Pavement Technology Center (CP Tech Center) at Iowa State University has recently published a comprehensive "Guide to Full-Depth Reclamation (FDR) with Cement." This 90-page manual was developed in cooperation with the Portland Cement Association and many product experts from around the country, including CCT's own Matthew Singel. It will serve as a centerpiece in CCT's just-announced one-day seminar series "Best Practices for Cement Stabilization and Roller-Compacted Concrete Pavements," to be held at seven Texas locations between August and December, 2017. FDR is often the lowest-cost method of recycling failed asphalt pavements into highly durable bases. It is an in-place operation that pulverizes the existing surface and base, then adds a small amount of cement to provide a fast-curing and long-lasting base that stands up to heavy trucks and saturated conditions. Construction is fast, often completed in one day, so light traffic can be applied afterwards; and the need to excavate huge amounts of old material and replace it with new base material--and the associated heavy truck traffic--is avoided. The guide provides not only an introduction to FDR with cement, but it also comprehensively covers key topics:
If you are interested in being trained in this technique, using the new guide, please consider attending one of the CCT's 7 upcoming seminars. To find out more about FDR, and download the guide, visit the CP Tech Center's website.

San Antonio's Belknap Place is over a century old, and still going strong. Last May, it was commemorated with a Texas State Historical Marker, and in December the American Concrete Pavement Association presented its Longevity Award to the City for Belknap Place. As President Trump contemplates a $1 trillion infrastructure investment, and the ASCE discusses America's overall D+ in its 2017 Infrastructure Report Card, Belknap Place stands as a monument to wise public investment in a resilient technology.

PURPOSEThe Cementx Pavement Blog seeks to make pavement owners, engineers and contractors smarter about selecting, designing, constructing and maintaining pavements. New blog postings began February 1, 2017; however, we carried over pavement-related blog postings from our older blog, the "Texas Cement and Concrete Blog," which ran until December 2016.
