Abstract:This paper discusses the performance requirements of concrete pavements from the standpoint, primarily, of the quality of the concrete as a material. It is pointed out that the lack of durablity of much of our present day concrete may be due to our methods of construction. The writer believes pavement durablity could be significantly improved by using a scientifically proportioned mix of dry consistency, well compacted by vibration or tamping, and with close control over aggregate gradation, in place of the oversanded plastic mixtures which we now use. He does not believe in air entrainment is necessarily the final answer to our problem of surface deteroration but that we should seriously consideroverhauling our entire construction practice as well as our present methods of controlling the uniformity of aggregate gradations. Current practice in the construction of concrete pavements and airport runways in Great Britain and past practice in Germany in the construction of the autobahen are discussed to show that the placing of harsh, dry mixtures with close control of aggregate gradations is entirely feasible from the construction standpoint.
