Full Description

Fast-track concrete paving helps contractors improve profits with time-of-completion incentives. It also helps public agencies combat increasing public impatience with traffic interruptions during pavement repair or replacement. But successful use of this powerful technology requires agencies and contractors to change traditional construction specifications and processes. Accelerated Techniques for Concrete Paving describes the needed changes and also applications for roadways, airfields, and other pavements. You'll get recommendations for planning, concrete materials and properties, jointing and joint sealing, curing and temperature control, concrete strength testing, and opening the pavement to traffic. An appendix gives flexural strength requirements for opening to traffic. These requirements vary with pavement class (municipal or highway), foundation support value, and expected loading, expressed as equivalent single-axle loads.

With the new accelerated techniques, concrete pavements can be opened to traffic in 12 to 48 hours, while traditional techniques require waits of 5 to 14 days. This fast-track approach allows transportation officials to complete projects that under normal time frames would simply not be feasible.
