    Abstract

    This report documents the development of a slurry seal and wheelpath inlay study. The objective of this study is to develop quick inexpensive procedures to improve skid resistance, extend the useful life of a pavement, and to reduce wheelpath rutting on bituminous concrete pavements.

    A two-course asphalt emulsion slurry seal was constructed on two sites to monitor the extension of useful pavement life and improved skid resistance. The slurry seal increased the useful pavement life for at least three years and improved the skid resistance by approximately 30%.

    A wheelpath inlay was constructed on a severely rutted bituminous concrete pavement. Rut depth and skid resistance data were taken before and after construction. The inlay appears to offer an effective, alternate, less costly procedure for correcting wheelpath rutting.

    Recommendations are presented for the use of the slurry seal and the wheelpath inlay.
