Evaluation of Trapezoidal Shaped Grooves

 the width of the bottom of the groove should be 1/4 in., ±1/16 in., and the spacing between groove centers should be 2 1/4 in., +0/-1/8 in.  Analysis of all data collected in this research effort indicates that the trapezoidal-shaped grooves should be considered an acceptable option for pavement grooving on airports.
