Is your knowledge up to date on how to design, construct and maintain concrete pavements? Do you know current best practices for stabilizing base materials and soils with cement? Have you considered roller-compacted concrete for a street or industrial site, but don't know how to design or specify it? Are you giving your clients--public agencies, facility owners, the traveling public--the best performing pavements at the lowest cost? If these or similar questions are on your mind, then the Cementx Pavement Blog is for you. Also, you can register for updates and a free giveaway.

Concrete pavement overlays can be an economical method to rehabilitate both concrete and asphalt pavements (see the Guide to Concrete Overlays from the National Concrete Pavement Technology Center.) But, the concrete overlay pavement design methods being used today, yes even AASHTO ME, are overly conservative. Why should a concrete overlay of an asphalt pavement in structurally good condition be only 2 inches thinner than a new concrete pavement on a subbase and subgrade. Better methods are available--just not used--to take advantage of the existing pavement structure. By: Richard B. Rogers, PE
If your concrete pavement is starting to show some distress, then it may be time give it a new life with a bonded concrete overlay. A 4-inch bonded concrete overlay is faster and more economical than full reconstruction or an asphalt overlay and has a history of providing 25 years of service with excellent performance. Bill Brudnick, Houston District Design Engineer or Mike Hallum, Wichita Falls District, Area Engineer have both had successful experiences with thin bonded overlays. The CCT can provide examples, design strategies, and construction techniques...just contact us.

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.
