Carlo simulations to determine the impact of flexible and rigid pavement deflection on passenger car and truck ... their strengths and shortcomings
Asphalt (specifically, asphalt concrete), sometimes called flexible pavement due to the nature in which it distributes loads, has been widely used since the 1920s. The viscous nature of the bitumen binder allows asphalt concrete to sustain significant plastic deformation, although fatigue from repeated loading over time is the..
These types of composite pavements give significant flexibility to the designer to optimize the pavement design in terms of life-cycle costs, reduction in future lane closures, and improved sustainability. They essentially exhibit the advantages of conventional HMA and PCC pavements while reducing their disadvantages
