    Laboratory study on recycled concrete aggregate based

    Jul 20 2020 Asphalt is the surfacing material for flexible pavements. It is basically a mixture of aggregates and bituminous binder. Substitution of natural aggregates with recycled concrete aggregates RCA promises to be of much benefits as aggregates make up to 85 of asphalt mixtures Das et al. 2019 Rafi et al. 2011.

  • Investigation of recycled concrete made with limestone

    Investigation of recycled concrete made with limestone

    A basic requirement for producing high-quality recycled aggregate is the selection of the material entering the preparation process. This pre-sumes a well-organized acceptance and storage of incoming material as well as effective material management. One of the techniques used to prepare RCA is the use of picking belts that enable the separation

    Blending of recycled glass and crushed rock in road pavements

    Mar 19 2020 Recycled glass is a mixture of different coloured glass particles with debris. It is the result of crushing the waste glass collected from residential and industrial areas. Construction and demolition CampD materials such as concrete excavation stone basalt and brick make up a significant proportion of the waste materials present in landfills in Australia.

  • Potential of Natural and Recycled Concrete Aggregate

    Potential of Natural and Recycled Concrete Aggregate

    This study investigates the feasibility of using recycled concrete aggregate RCA as a partial substitution of natural aggregate in pavement engineering. Despite RCAs good properties such as polishing value and freeze-thaw resistance its use is limited by low resistance to fragmentation and high-water absorption. This paper parent the experimental results of mineralogical-petrographic .

    Mar 25 2020 The type of binder differentiates the two most significant pavement types which are flexible pavement and rigid pavement. In the case of rigid pavement Portland cement is used as the binder and bitumen is used as a binder for flexible pavement. Asphalt concrete is a mixture of aggregates and bitumen.
