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.
