Evaluation of the Effectiveness of Ultra High Pressure (UHP) Water Cutter to Treat Flushed Asphalt Pavements

Research output: Contribution to conferencePaperpeer-review

Abstract

The use of Ultra-High-Pressure (UHP) water to cut into asphalt pavements and remove excess asphalt has been successfully used by highway agencies since the early 2000’s. This technology has been applied in the United States for much longer to clean Portland cement concrete surfaces. However, its use to re-texture flushed asphalt pavements appears to have, at least in the recent past, originated in New Zealand and Australia. The Bryan District of Texas Department of Transportation (TxDOT) initiated activities to adapt the use of water cutting equipment developed in the United States to improve skid resistance in flushed asphalt pavements. This led to TxDOT sponsoring a research implementation project to evaluate the effectiveness of this technology by monitoring the performance of water cutter treated pavements for a two-year period. This paper presents findings from the early stages of this study by focusing on the improvement of macrotexture and skid resistance of flushed asphalt pav
