The Kansas Department of Transportation (KDOT) has a long history of aggregate research directed towards finding the most reliable and durable aggregate for highway construction. Beginning with a study on freeze thaw durability in 1928, this paper summarizes the historical development of aggregate research conducted over the last 75 years. Research studies have focused predominately on freeze thaw damage (D-cracking) and alkali-silica reaction (ASR). This research has contributed significantly towards the development of current specifications. Today KDOT pavements are relatively free of ASR and D-cracking. Current test methods and concrete aggregate specifications have been included in the Appendix.
