Improving Highway Surface Course Properties of Asphalt Concrete for Heavy Traffic Loading using Mineral Fillers
Abstract: Failure signs seen on both rigid and flexible pavement as distresses is most often instigated by mix properties of the surface due to many factors. Traffic loading, Stripping or raveling is another possible cause of such effects. Stripping occurs when poor adhesion between asphalt cement and aggregate allows the aggregate at the surface to dislodge. As a result, mineral fillers in hot-mix asphalt concrete to obtain certain desirable properties has …

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 …

Whispers of the Microbial World: Unveiling Bacterial Dialogues through Quorum Sensing
Abstract: Quorum sensing is a special way of bacteria by which they can regulate their own gene expression as per the population density of the bacteria. It is basically a type of cell-to-cell communication pathway used by the microbes. The signal molecule which helps in this mechanism are called auto inducer(AI). As the mechanism depends by changes in the cell density, so when the cell density reaches to the threshold cell …
