摘要

It's no secret that the world economy has descended into what some say is the worst recessionary cycle since the Great Depression some eight decades ago.rnThere have been few safe harbors from the downturn, which has had a significant effect on the road-building community.rnAll of this has required states, counties and municipalities, as well as the industry, to meet the critical needs of highways, roadways and airports with fewer resources. It is not surprising that overlays have become a mainstay of pavement preservation and rehabilitation, but what many may not realize is that concrete overlays are becoming used increasingly throughout the nation.
