• Abstract:
  The implementation research project described herein has been designed to conduct a systematic evaluation of the ultra-high pressure (UHP) water cutter as a pavement preservation tool for treatment of flushed, sealcoat surfaced pavements in Texas. Relative to treatment effectiveness, comparison of pre- and post-treatment data from multiple sets of friction and texture tests collected from 14 sites located in four climatic regions in Texas indicates that the UHP water cutting treatment generally yields significant improvement in pavement macrotexture and microtexture. Relative to treatment durability, follow-on evaluation of these same parameters is currently underway. Limited data based on one follow-on event six months after treatment suggest that the initial improvement associated with UHP treatment has decayed, but pavement surface friction and texture are typically still much higher than they were prior to treatment. Relative to production considerations associated with the UHP water cutter treatment process, a direct comparison of unit cost data for UPH water cutting versus the unit costs of other maintenance functions currently used to treat flushed pavements in Texas indicates that UHP water cutting can provide cost savings of 25 percent to 77 percent, typically 41 percent. Overall, the interim findings from of this implementation study are promising relative to the application of UHP water cutting for seal coat maintenance in Texas.
