| 摘要： | 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 predominantly on freeze-thaw damage (D-cracking) and alkali-silica reaction (ASR). This research has contributed significantly towards the evelopment 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. |
