• Abstract:
  With the current level of deterioration of pavements in Oklahoma and the United States a satisfactory repai ; technique that is economical and can be applied rapidly while resisting a significant volume of traffic is becomin ; important. Thin concrete overlays have been used in increasing numbers over hot-mix asphalt (HMA ; pavements and at intersections as a rapid and economical method of repair. These repairs have show ; outstanding service in the state of Oklahoma with service lives over 10 years when used in areas with moderat ; truck traffic. These overlays are commonly referred to as white toppings as the overlay material is much lighte ; than the asphalt it is overlaying. ; This report is organized in three major sections. In section 2 the current condition of whitetopping projects ; is reviewed in Oklahoma. The inspection of these projects was primarily done with visual inspection, but ; some work was done with cores from the projects and also with Falling Weight Deflectrometer (FWD) ; measurements. In section 3 a review of the different whitetopping design methodologies is presented. In ; section 4 specific unanswered questions over whitetoppings are covered that the Oklahoma DOT felt were ; important to address from the existing literature.
