"Extending Asphalt Pavement Life Using Thin

Due to budget constraints, many highway agencies are becoming interested in pavement preservation or rehabilitation rather than reconstruction to ensure pavement is in serviceable condition. Thin whitetopping (TWT) is the process of rehabilitating distressed asphalt concrete (AC) pavements by using a concrete overlay. This study was done to develop a design catalog for existing AC pavements to ...

The thin white topping (TWT) can be a cost-effective measure that extends the life of existing asphalt pavements. This project is aimed at calibrating the TWT design method developed by the Colorado Department of Transportation using data from an experiment conducted under the accelerated pavement testing (APT) program at Kansas State University.

Thin Whitetopping – Pavement Interactive

Thin Whitetopping. Thin Whitetopping (TWT) is a 4 to 7 in. thick concrete overlay bonded to an existing ACP to create a composite section. TWT is typically constructed at intersections where rutting and shoving in asphalt pavement continue to cause problems. TWT may also be used at access or exit ramps to interstate highways, entire sections of ...

Whitetopping/Ultra Thin Whitetopping

Whitetopping provides a unique solution to this repair cycle by using the asphalt pavement's structural capacity to overlay a thin sheet of concrete onto the existing pavement. Effectively breaking the asphalt repair cycle, a concrete surface can be designed to last up to 40 years with minimal maintenance.

Use Good Compaction to Extend Pavement Service Life

When compaction is enhanced, in-place density can be optimized, thereby improving durability and extending pavement service life. A review of several past studies clearly shows the effect of reduced air voids on improved fatigue and rutting performance of asphalt mixes, both in the lab and in the field. Depending on mix type and experiment ...
