Wear Resistant Pavement Study

This report documents the construction of three special pavement test sections on I-90 east of Spokane, Washington. The test sections included ultra-thin and thin whitetopping, Modified Class D open graded asphalt concrete, and micro/macro surfacing treatment. The majority of the project was built with a ½-in. Superpave mix. The test sections were built to assess their potential as mitigation measures for studded tire wear. Initial data collected on the sections indicate a rate of rutting of 1.8 mm per year on the whitetopping, 2.2 mm per year on the Modified Class D and Superpave sections, and 2.6 mm per year on the micro/macro surfacing section. Extensive cracking was noted in the section of whitetopping with a 3-in. thickness.
