Contractor expands highway from the highway

Article Abstract:

Meridan, CT-based Lane Construction used a movable concrete barrier system tofacilitate the widening of Interstate 66 in Fairfax, VA. The Virginia Dept of Transportation had stipulated that barriers be used and allowed only four-hour and eight-hour lane closures during day and night, respectively. The company used the Quickchange system which can be moved laterally by a transport/transfer vehicle. The system allowed for adequate construction staging area on the roadway itself. The full-lane closures enabled the contractor to reach the whole work area from the road and conduct operations insequence.

Asphalt update

Article Abstract:

The Superpave system developed during the Strategic Highway Research Program (SHRP) provides major improvements in design and construction of asphalt pavements. The Superpave offers an improved methodology for design and analysis of mix material components, and predicts the future performance of pavements. The Superpave system consists of performance-based binder specifications, mix tests, and mix design and analysis. The SHRP binder tests impart an improved tie to the performance and can alter the construction practices leading to guaranteed constructions.
