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… Read the rest
