Asphalt pavements are the most common type of pavements in North America. Increasing traffic demand, harsh weather conditions, and the tendency for infrastructure operators to reduce the cost (and, therefore, the frequency) of maintenance are the major reasons for asphalt performance improvement...

Development of Solvent Selection Criteria Based on Diffusion Rate, Mixing Quality, and Solvent Retrieval for Optimal Heavy-Oil and Bitumen Recovery at Different Temperatures
DownloadFall 2015
Heavy-oil and bitumen recovery requires high recovery factors to offset the extreme high cost of the process. Attention has been given to solvent injection for this purpose and it has been observed that high recoveries are achievable when combined with steam injection. Heavier (“liquid”) solvents...

Circular turbulent jets are essential in many engineering applications and are thoroughly studied. Most of these studies involve stationary jets. Contemporary studies lack the understanding of translating jets partly because the experimental setup is complicated, and computational models cannot...

Evaluation of Mechanical Performance of Asphalt Emulsion Stabilized Base Course Using Asphaltenes or Cement
DownloadFall 2021
Civilization has become highly reliant on the road industry in recent years for both commercial and personal purposes. A typical road's function is to promote traffic flow comfortably and safely. The pavement is a structure made up of natural ground with varying layers on top that can distribute...

This research was undertaken to study the performance of paraffinic solvents at higher temperatures for heavy oil/bitumen recovery. Heavy oil or bitumen saturated glass bead packs, Berea sandstone and carbonate cores were used in the experiments to represent different types of pore structures,...

Sinkholes are frequently reported around the world, and soil erosion around defective sewer pipe is found to be one of the possible cause of sinkholes. As water infiltrates through the defect in a pipe, soil can be washed into the pipe leading to a cavity or even sinkhole formation. Besides,...
