Guide Specifications for the Construction of Chip Seals and Microsurfacing

Pavement preservation provides a means for maintaining and improving the functional condition of an existing highway system. Although pavement preservation is not expected to substantially increase structural capacity, it generally leads to improved pavement performance and longer service life. Chip seals and microsurfacing are frequently used as pavement preservation treatments on flexible pavements. Although a great deal of information on the design, materials, and construction practices of chip seals and microsurfacing is available, there is no nationally accepted guidance on their construction. There is a need to develop guide construction specifications to help highway agencies apply chip seals and microsurfacing treatments more effectively and achieve the most benefit of their application. The objective of this research is to develop recommended guide specifications for the construction of chip seals and microsurfacing.
