in this study, the corrosion resistance of a bituminous coating reinforced with different ratios ofnanoclay pigment was studied. to make nanocomposite coatings, 2, 3, and 4 wt.% of clay (cloisitena+) were incorporated into water emulsified bitumen. the coatings were applied to steel 37. opticalmicroscopy and x-ray diffraction (xrd) were used to characterize the nanocomposite structure. inorder ...

Weak bonding between layers of pavement leads to damages on the composite pavement. Bonding plays an important role in the durability and maintenance of composite pavement layers. The present study evaluates the factors effective in bond strength of the interface between concrete and asphalt pavements. The factors considered for this purpose include steel slag percentage in the concrete pavemen...

Asphalt mastic is the most important binder in asphalt mixtures and its rheology inevitably influenced by mineral aggregates. Due to little consideration that has been paid aggregates’ effects, rheological properties of films have not accurately characterized for present method. Therefore, this study aimed investigate characteristics affected aggregates reveal fundamental mechanism interfacial ...

Production of highly viscous tar sand bitumen using Steam Assisted Gravity Drainage (SAGD) with a pair of horizontal wells has advantages over conventional steam flooding. This paper explores the use of Artificial Neural Networks (ANNs) as an alternative to the traditional SAGD simulation approach. Feed forward, multi-layered neural network meta-models are trained through the Back-Error-Propaga...

Solvent–steam mixture is a key factor in controlling the economic efficiency of the solvent-aided thermal injection process for producing bitumen in a highly viscous oil sands reservoir. This paper depicts a strategy to quickly provide trade-off operating conditions of the Expanding Solvent–Steam Assisted Gravity Drainage (ES-SAGD) process based on Pareto-optimality. Response surface models are...

Canada has experienced a significant increase in the transport of diluted bitumen (dilbit), a predominant oil sands product that combines bitumen with diluents derived from oil-gas condensates and other proprietary compounds. The proportion of diluent and the chemical composition of dilbit vary to meet seasonal transport requirements. While the toxic effects of a variety of crude and refined oi...
