Effect of Various Metal Hydroxide Flame Retardants on the Rheological Properties of Asphalt Binder
Metal hydroxide has been widely used as flame retardant to reduce the hazards of tunnel fire, however, few researches investigate its effect on the rheological properties of asphalt binder systemically.

Performance of Indiana's Superpave HMA Mixtures
This project followed the performance of a number of hot mix asphalt paving projects for seven to eight years in an attempt to relate laboratory test results to field performance. First, a small scale study compared sampling locations, specific gravity test procedures and compaction devices used on two samples from projects, one with volumetric ...

Climate change is increasing the frequency and intensity of extreme weather events, posing challenges to the durability of asphalt road pavement systems. Incorporating waste plastics, such as polyethylene terephthalate (PET), into asphalt mixtures has been proposed as a potential approach to reduce bitumen demand and modify mechanical performance ...

Laboratory and Field Evaluation of Modified Asphalt Binders and Mixes for Alaskan Pavements [PDF]
In order to properly characterize modified asphalt binders and mixes for Alaskan pavements, this study evaluated properties of 13 asphalt binders typically used in Alaska from three different suppliers, and 10 hot mix asphalt (HMA) mixtures which were ...

Abstract The longevity of porous asphalt pavement is inevitably compromised by the clogging of voids by various particles, leading to a degradation in its drainage function. Numerical simulations with real pore structures were used to investigate the clogging behavior of porous asphalt concrete (PAC) to clearly and intuitively understand its void ...

Using Historic Pavement Performance Data to Identify and Select Sites for Asphalt Mixture Design Studies [PDF]
Since 1997 Arkansas asphalt mixtures have been designed using a procedure commonly known as ‘Superpave’. In a traditional Superpave mix design, the design considers only traditional volumetric parameters; however, recent advances in mix design technology

Mapping Temperature Zone of Ethiopia for Binder Performance Grading System
Several studies from the Strategic Highway Research Program (SHRP) have demonstrated that improving asphalt binder standards by incorporating performance‐based characteristics can benefit road network administrators. This approach provides a better understanding of pavement behavior during its operational phase.
