During 2004, CEMEX, the second largest supplier of cement products in North

America, began to promote the use of the micro-cracking construction method

in southern California. This prompted the adoption and successful use of the

Bryan, Texas specification by the Cities of La Quinta and Santa Rosa, California

in 2005. As shown in the figures below, the QC test data is very similar to that

achieved in Texas three years earlier. The construction method apparently

affords consistent results job-to-job even with the expected variabilities in

materials and construction. CEMEX has also secured commitments from several

other southern California cities to use the method. In 2006, CEMEX will expand

its promotion of this construction method to include all of the southwestern

United States and Mexico.
During 2005, the Montana Department of Transportation judged the benefits

sufficient to adopt the Bryan, Texas specification for use during the 2006

construction season.
