  • Recycling of different plastics in asphalt concrete

    2019-1-1 · The benefits and environmental implications of utilizing various recycled PWs in asphalt concrete is examined. The PW-modified binders are subjected to series of tests to establish their upper temperature performance limit. Asphalt concrete mixtures of selective PW-modified asphalt binders are formulated and analyzed. Emission estimates related to some selective potential blends are estimated and compared to conventional and virgin polymer asphalt.

  • Graniterock: Recycling Asphalt And Concrete

    Recycling has become an integral part of the construction industry during the 1980s. The advent of recycling concrete and asphalt into aggregate base materials has satisfied many needs. It has helped reduce ecological pressures on our community, while simultaneously offering us a viable and competitive source for “spec” aggregate base material.

  • Thermal Properties of Some Asphaltic Concrete Mixes

    the subject of heat transfer in asphaltic concrete recycling appears to refute many of the contractor claims previously mentioned. Carmichael et al. (!l_) modeled an asphaltic concrete pavement as a semi­ infinite solid and used a forward difference numeri­ cal method to solve the governing differential equa­ tion.
