Abstract:

A survey of pavement grooving operations made at military and commercial airfields and by State Highway Departments is intended to serve as a basis for future evaluation of the effects of grooving on deterioration of rigid and flexible pavements. The survey covers runway grooving operations at seven airfields, grooving test installations at six airfields, and highway grooving by twelve State Highway Departments. Most of the pavement grooving has been accomplished within the past 2 years, and present pavement performance data are limited to this short period. The main difference between air-performance data are limited to this short period. The main difference between airfield and highway grooving has been in the direction of the grooving, airfield grooving being predominantly transverse and highway grooving parallel to the direction of traffic. However, there has been appeciable difference in performance of grooved airfield and highway pavements. Present condition of both rigid and flexible airfield pavements that have been grooved has been satisfactory with little evidence of deterioration. Grooved portland cement concrete highway pavements also have given satisfactory performance, with minor deterioration in cold weather areas attributed to use of tire chains and studded tires. Grooved asphalt concrete highway pavements have deteriorated rapidly in wheel paths where the grooves are obliterated leaving a shallow dishing effect. Because of differences in traffic volume and traffic patterns, separate pavement performance evaluations are necessary for airfield and highway pavements.
