Cold In-Place Recycling


4. A high-precision belt scale weighs the moving material before it enters the pugmill mixer. An on-board microprocessor continuously adjusts the flow of asphalt emulsion, water, or other liquid additive so that the correct ratio of additives to the milled material is maintained regardless of variations in the milling depth and speed. The pugmill is also regulated so that the final mix is homogeneous.



5. The millings are uniformly coated for maximum long-term cohesion and surface strength before the recycled mix is deposited behind the train and spread by the paver. Optional windrow placement of recycled asphalt adjacent to the roadway allows for the subgrade modifications or stabilization.



6. Conventional hot-mix pavers equipped with automatic screed controls spread the recycled asphalt to the specified depth and width.
