Samenvatting
As the highway infrastructure ages, many highway agencies are focusing on rebuilding existing roadways instead of building new ones. Highway improvement projects being performed on roadways that are open to traffic are increasing. At the same time, traffic continues to grow and creates more congestion. This combination of more work zones, heavier traffic, and greater reliance on night work results in increased risk for highway workers. The methods presented in this brochure can be used to minimize and control risks for workers. (Author/publisher)
