Rising energy prices since 2008 have improved concrete’s relative competitive position against asphalt and led to a greater market share for U.S. highway paving. Through the third quarter in 2011, concrete’s market share of U.S. highway paving volume stood at 16.8 percent, its highest level on record, based on available data through 2003. The previous high was 15.2 percent in 2003.
The paving market shares for volume are calculated based on the amount of each material’s paving tons as a percentage of total tons bid for the specific year. Using Oman Data Systems that provide state DOT bid tabulations, PCA gathers highway paving volume and spending information by state.
