Feasibility of Using Precast Concrete Panels to Expedite Highway Pavement Construction;Research rept. Sep 99-Feb 00

摘要

As the number of vehicles on America's roadways continues to grow at an unprecedented rate, pavements continue to deteriorate faster and require more frequent replacement. Construction, however, causes traffic delays, which further compound the problem. Traffic delays increase user costs, which are costs incurred by the users of the roadway but are directly caused and attributable to the presence of construction activities. Therefore, a method for expediting pavement construction in order to reduce user costs is needed. This report describes a method for expediting highway pavement construction through the use of precast concrete panels can be assembled quickly, allowing traffic back onto the pavement almost immediately. This kind of assembly will allow pavement construction to be carried out in overnight or weekend operations, when traffic volumes are low. The result will be a tremendous savings in user costs.
