The Study of Recycler Unit Operation Using Physical Scale Modeling

One of the promising waste-free technologies in construction is road repair and rebuilding using cold and hot recycling methods. This technology involves high-speed road resurfacing by one, or a set of machines performing milling of the worn-out layer, adding a binder, mixing the binder with the damaged and granular material of the old coating, laying and compacting the new pavement. The authors examine particular features of units of the recycler used for repairing and rebuilding road surfaces, on a physical scale test stand. The formulas for recalculating the main parameters from the model to the original surface are obtained. The paper describes the capabilities of the test stand for studying the recycler units (milling tools when working on various types of surfaces), milling process, stabilization of the road surfaces by the binder, and for developing technologies for new road pavements.
