PAVEMENT PATCHING TECHNIQUES AND MATERIALS

The New Jersey Department of Transportation has conducted a study to find materials suitable for rapid, relatively long lasting, economical winter patching of portland cement and bituminous concrete pavements and to develop efficient techniques necessary for their placement. Overall, the Department's standard winter mix (RR) performed very well as compared to the other materials tested. It was also the most cost-effective of the cold winter mixes used in the study. The other two cold mixes investigated (Zero-mix, a proprietary patching material used in New Jersey and an asbestos modified RR mix) did not prove to be suitable patching materials. This was due to lack of any significant improvement in patch life and higher seasonal costs as compared to the standard RR mix. Also, there was potential health hazards involved with the asbestos modified material. FABC hot plant mix out performed the standard RR mix technique for technique. It was also the most cost-effective of the materials tested. However, FABC is not readily available at the present time during mid-winter. Also discussed in this report is the effect of weather, traffic volume, and the various compaction and pothole preparation techniques on patch durability.
