Abstract

In order to find methods to restore rutted asphalt pavements and increase their rutting resistance, field tests have been carried out with thin, high strength concrete overlays (whitetoppings) placed on top of the milled asphalt pavement. The concrete overlay was limited to 70 mm. Both plain and steel fibre reinforced concrete have been studied. Two different joint spacings have been investigated: 1.25 and 3.5 m. Also a test section with an overlay consisting of open asphalt filled with high strength cementitious mortar has been included in the investigation. After three years in service, the test section performance is promising. Besides test results, the paper provides recommendation for the construction of whitetoppings and suggests needs for further research.
