Asphalt Pavement. While recycled asphalt pavement was not reported separately in these data, generation of "inert solid waste," which consists of concrete, asphalt, dirt, brick and other rubble, was conservatively estimated at 8.2 million tons. The estimated recycling rate for inert solid wastes was 57 percent; the remainder was disposed of.

Approximately 9 million tons of roofing waste are generated annually in the United States. Disposal costs are significant.
Learn MoreThe feasibility of using concrete containing recycled asphalt pavement (RAP) in concrete pavement applications was evaluated. Recycled asphalt pavement (RAP) is the removed pavement material
Learn MoreAsphalt isn't biodegradable, meaning it ends up sitting in a landfill, which is why using recycled asphalt pavement is much better for the environment. Recycling asphalt also helps conserve natural resources and reduce air pollution.
Learn Morefeasibility of using recycled materials in . One of these materials is asphalt pavements crumb rubber, obtained from recycled rubber tires, used as an additive to conventional Hot Mix Asphalt (HMA) to produce Rubber Modified Asphalt (RMA). These tires would otherwise end up in landfills, which is undesirable when considering sustainability.
Learn Moreabout the feasibility of using the recycled aggregate from this CDW to produce dense graded hot mix asphalt (HMA) concrete for the surface course of medium and low traffic pavements in the region. However, particle breakage and high water absorption of the recycled aggregate remained a major cause of concern.
Learn MoreReclaimed or recycled asphalt pavement (RAP) consists of milled or excavated asphalt pavement which is crushed and screened into different sizes to meet specified grading requirements. RAP can be used in many road related applications but the focus of this paper is on its use as aggregate in plant hot mix asphalt. The hot recycling of asphalt is done in a central mixing plant and involves
