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 …

Dosing Control of Urea in Selective Catalytic Reduction (SCR) to enhance the reduction of Nitrogen oxides
Abstract: Selective Catalytic Reduction (SCR) is an effective aftertreatment technique designed to comply with rigorous emission criteria established by global regulatory authorities for the elimination of nitrogen oxides from exhaust streams. Since NOx and ammonia reagents are poisonous and an excess of either is therefore very undesired, it poses an intriguing control problem, particularly at high conversion. SCR systems must reduce NOx emissions as much as possible and reduce the possibility …
