Design Mixture of RAP-HMA Pavements: A Review

Evaluation of the Effects of Recycled Asphalt Pavement (rap) on an Ndot Hma Mixture

Ncat Completes a National Study on Segregation in Hma Pavements

Putting Research Into Practice Page 10 The National Center for Asphalt Technology (NCAT) has just completed a National Cooperative Highway Research Program (NCHRP) Project: NCHRP 9-11, “Segregation in Hot Mix Asphalt Pavements.” Dr. Mary Stroup-Gardiner was the principal investigator on this project. Segregation has historically been defined to mean localized areas of coarse materials in some a...

Federal Aviation Administration Undertakes Major Hma Research for Airfield Pavements

The Federal Aviation Administration (FAA) has undertaken a major hot mix asphalt (HMA) research program for airfield pavements. The Airfield Asphalt Pavement Technology Program (AAPTP) was established in fiscal year (FY) 2004 through a cooperative agreement between the FAA and Auburn University. The program will be funded by the FAA and will be administered by Auburn University. A t o t a l o f...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Decolorization of mixture of dyes: A critical review

Water plays a vital and essential role in our ecosystem. This natural resource is becoming scarce, making its availability a major social and economic concern. Use of a large variety of synthetic dyes in textile industries has raised an hazardous environmental alert. About 17 - 20% of freshwater pollution is caused by textile effluents. These effluents are recalcitrant to biodegradation and cau...
