NASA DIAGONAL-BRAKED TEST VEHICLE EVALUATION OF TRACTION CHARACTERISTICS OF GROOVED AND UNGROOVED RUNWAY SURFACES AT MIAMI INTERNATIONAL AIRPORT, MIAMI, FLORIDA, 8-9 MAY 1973

Two runways were evaluated under artificially wetted conditions with the NASA diagonal-braked vehicle (DBV). Results of the evaluation which included a pavement drainage analysis, a pavement skid resistance analysis, and a DBV wet/dry stopping distance ratio analysis indicated that the ungrooved runway surfaces had poor water drainage characteristics and poor skid resistance under wet conditions at high speeds especially in rubbercoated areas of the runways. Grooving runways to a transverse 1-1/4 x 1/4 x 1/4 inch pattern greatly improved both the water drainage and pavement skid resistance capability of these asphaltic concrete surfaces.
