The resilient modulus (MR) of unbound materials is a required input in most of the mechanistic-based pavement analysis and design process and has a significant effect on the projected pavement performance in the mechanistic– empirical pavement design guide programme or AASHTOWare DARwin. The Iowa Department of Transportation (DOT) recently acquired a servo-hydraulic dynamic loading materials te...

The urban, constructed areas are full of buildings and different kinds of pavements and have a noticeable lack of trees and flora. These areas are accumulating the heat from the Sun, people, vehicles, and constructions. One interesting heat collector is the asphalt pavement. How does the heat transfer to different layers under the pavement or does it? What are the temperatures under the pavemen...

In the construction and maintenance of asphalt pavement, reclaimed pavement (RAP) is being widely used as a cheaper alternative to conventional hot mix (HMA). HMA incorporated with high RAP content (e.g., 40%), which most commonly used, may have prominent adverse effects on life cycle, performance properties, related costs. Thus, before utilizing RAP, it essential investigate whether still econ...
