ABSTRACT

ABSTRACT: NJDOT is evaluating the benefits of pavement preservation surfaces and techniques for interstate rehabilitation as a method to increase pavement life while reducing overall cost. A preliminary noise evaluation was conducted at the tire/pavement interface to compare the alternative surfaces to existing in-service pavements as part of a trial study being conducted by the NJDOT. Pavement preservation surfaces provide a benefit in relation to the speed of construction, which reduces the time required for lane closures, increasing public acceptance. Micro-surfacing and chip-sealing were specifically identified as having the highest potential to be applicable at the interstate level. The outcome for the project is to determine an appropriate treatment to reduce oxidization and extend pavement life quickly for a relatively low cost, when a 2% distress level is identified.
