Rheological Characterization of Bituminous Binder containing Wax based Warm Mix Asphalt Additive
Warm mix asphalt (WMA) has been gaining increasing popularity in recent years due to energy savings and environmental benefits. The mechanism of WMA is to use some additives or technologies to reduce the viscosity of bitumen and to modify the rheological behavior of bituminous binders, and thus improve the workability of the mixture at lower temperature. In this study a paraffin wax based addit...
متن کاملAn Alternative Asphalt Binder, Sulfur-Extended Asphalt (SEA)
Background In the early 1970s, due to concern over asphalt cement supply issues and an anticipated over abundance of elemental sulfur, many organizations Société Nationale des Pétroles d’Aquitaine (SNPA), Gulf Oil of Canada, Sulfur Development Institute of Canada (SUDIC), Texas Chemical Company, U.S. Bureau of Mines, and the Texas Transportation Institute) began to evaluate the potential for su...
متن کاملThe Effect of Binder Components and Powder to Binder Ratio on Rheological Properties of Mg-SiC Feedstocks
Rheological characteristics of powder injection molding PIM feedstocks play an important role in final properties of manufactured MMCs. In this study, six formulations composed of magnesium and SiC powder (99:1 wt.%) and a specific binder were prepared to investigate the influence of binder composition, powder to binder ratio, time and temperature on rheological properties of the feedstock. Th...
متن کاملCharacterization and Micromechanical Investigation of Recycled Asphalt Shingle Binder Blends
The sustainability movement has established a firm foothold in the Civil Engineering profession. The use of recycled asphalt shingles (RAS) is the latest development in the world of asphalt pavement sustainability. The relative abundance of tear-off shingles and their high asphalt content is driving RAS usage in highway and airfield pavements. However, the ultimate objective of any pavement sys...
متن کاملRheological Properties and Chemical Bonding of Asphalt Modified with Nanosilica
The objective of this study is to evaluate the rheological properties and chemical bonding of nano-modified asphalt binders blended with nanosilica. In this study, the nanosilica was added to the control asphalt at contents of 4% and 6% based on the weight of asphalt binders. Superpave binder and mixture tests were utilized in this study to estimate the characteristics of the nano-modifed aspha...
