GROOVING: NAFEC'S AIM IS TO CUT AIRPORT COSTS

This article describes a project that will evaluate new runway grooves patterns that could save airport operators and U.S. taxpayers millions of dollars in grooving and regrooving costs. This study will determine the lowest cost runway groove configuration which has acceptable performance. A test track was installed and the surface was grooved. Runway grooves spaced 2-1/2 inches apart with tolerances to 3 inches may provide acceptable braking for aircraft on wet runways. A jet-powered pusher car and dead load car are used to simulate landing speeds up to 150 knots and wheel loads up to 35,000 lb. per wheel. After the tests on the PCC surface has been completed, the PCC testbed will be replaced with an asphaltic concrete surface which will also be grooved and tested. Researchers also plan to test a new porous asphalt compound designed to provide rapid drainage, and a PCC surface in which grooves are made during curing instead of by post-cure cutting.
