Efforts to Improve the Life of Concrete Pavements in Virginia

2012 - CelikThe Virginia Department of Transportation has been active in improving the service life of concrete pavements in new construction and repairs. Several new technologies and practices have been successfully tried in the past decade. This paper addresses recent developments in design, materials, and construction practices and provides examples from newly constructed and repaired pavements. Some of these advancement areas are attention to foundation support, use of continuously reinforced concrete pavement (CRCP) along with its thickness and steel amount, new innovative construction practice using precast and prestressed slabs, use of wider slabs (truck lanes) to reduce edge stresses, use of large-size aggregate and pozzolanic materials in the mixture, implementation of trial batches and trial pavement sections, and attention to consolidation and curing during construction. These practices are expected to provide longer life. Recent projects have incorporated these practices. Examples included are the Route 288, Madison Heights Bypass, and Battlefield Boulevard interchange for CRCP projects for new construction and the
precast and precast prestressed pavements from I-66 for rehabilitation.

Presented at FHWA’s International Conference on Long-Life Concrete Pavements in 2012.
