Comparative Study between Conventional and High Strength Concrete
Abstract: The current trend of use of superlatives in concrete technology may strike as somewhat disconcerting to many. We had high strength concrete, hyper-plasticizer, and super plasticizers, very reactive Pozzolana, and now high performance concrete. It is difficult to imagine any concrete being manufactured and used, which is not intended to perform to the extent; high performance concrete is not a new material of construction. The sole distinction is the level …

Direct Estimation of Air Void Content from Gyratory Compaction History
Abstract: A computational approach is offered and explored for estimating the air void content of asphalt mixtures densified in the Superpave gyratory compactor. It entails fitting a sigmoidal function to the compaction history records of specimen height vs. gyration level. The compaction progress is then extrapolated mathematically to infinite number of gyrations for which the air void content is theoretically zero. The fitted densification curve is then used to estimate the …
