The Texas Transportation Institute (TTI) at Texas A & M University recently published Removing Excess Asphalt: Initial test of ultra-high-pressure water blasting a success.
The test was led by Darlene Goehl, P.E., an engineer with the Texas Department of Transportation (TxDOT) who sought a cost-effective option for correcting “bleeding” or “flushing.” Bleeding or flushing occurs when excess asphalt binding liquefies and rises to the surface–reducing traction and increasing a vehicle’s braking distance.
The goal of the demo was to remove the gooey excess binding without damaging the aggregate, so a section of highway with extremely heavy flushing was useed. Per the TTI and Ms. Goehl, it was a success.
Rampart Hydro was happy to participate in the demo, which was the first phase of implementing TxDOT research project 0-5230, which studied solutions to bleeding asphalt pavements. The study was led by Assistant Professor of Civil Engineering William Lawson, P.E., at Texas Tech University.
While we’re not mentioned by name in the web site report, there is a photo of Rampart’s BlasterVac cleaning head and one that shows a familiar blue, BlasterVac truck in the background. Well, we’re almost mentioned by name as “Rampart Hydro” is synonymous with with the successful application of “ultra-high-pressure water.”
