Effectiveness of Chip Sealing and Microsurfacing on Pavement Serviceability and Life

项目名称：	Effectiveness of Chip Sealing and Microsurfacing on Pavement Serviceability and Life
摘要：	Microsurfacing and chip seal are two of many preventive maintenance techniques used to retard pavement deterioration and prolong pavement life. Chip seal may be applied in one application; or two applications, known as double chip seal. Microsurfacing is a thin surface that is cold-applied. The paving mixture is composed of polymer-modified asphalt emulsion, 100 percent crushed aggregate, mineral filler, water and other additives. For many years, microsurfacing and chip seal have been assumed to be cost effective preventive maintenance techniques; however, a study is needed to validate this assumption and to provide further direction concerning optimal timing of these treatments as a function of pavement distress. The objective of the Effectiveness of Chip Sealing and Microsurfacing on Pavement Serviceability and Life project is to statistically determine the cost effectiveness of using chip seal or microsurfacing as a preventive maintenance technique.
