Appropriate Implementation of Pavement Preservation Treatments

This research conducted an extensive literature search of national, state, and industry pavement preservation and rehabilitation centers’ libraries for applicable treatments (pavement preservation, rehabilitation, and reconstruction) that the New Jersey Department of Transportation (NJDOT) could use on their high volume state-maintained roads. Reports in PDF format were collected and stored in an Access database to allow easy searches by NJDOT staff. A survey of all state DOTs was conducted to determine their use of these treatments. Fourteen states responded. The survey is summarized in volume 2 of this report. The authors' research partner, Deighton Associates conducted a survey and interviews of the state DOT contacts that use dTIMS Pavement Management System (PMS) software. A review of their PMS database identified what treatments were used, the treatment’s trigger, condition reset, life extension and costs. Summary tables are listed in this report. Based on the literature search and survey results, NJDOT selected seven treatment types that could be used in NJ. These included Fog Seal, Slurry Seal, Micro-Surfacing, Chip Seal, Cold In-place Recycling-Foamed Asphalt, Cold In-place Recycling-Asphalt Emulsion, and Hot In-place Recycling. Material and construction specifications, test methods (mix design, where applicable) and usage guides were developed. These are provided in volume 2. This research also summarized the effect of available suppliers and contractors on implementation. Some states limit the use of certain treatments based on the availability of contractors in their state. Demonstration projects which included Cold In-place Recycling, Full Depth Reclamation, Asphalt Rubber Chip Seal, Slurry Seal and Microsurfacing treatments provided training opportunities for NJDOT staff.
