Quality Management
Since the first paved pathways recognized as roads were built in biblical times, through the Roman era and into modern times, someone has been interested in the
quality of what was being done.  Whether it was the size of the stone in a cobblestone street or the amount of air entrainment in portland cement concrete, we, as
highway builders, have been concerned about...
