Cold recycling of asphalt pavements is a tried and tested method of recycling that can yield major savings in labor and materials, greatly reduce a project’s negative impact on the environment, and provide a sustainable answer to the problem of asphalt concrete maintenance. There are two types of cold recycling in ordinary use today; the first is cold in-place recycling and the other is cold central plant recycling. The current method of cold in-place recycling of bituminous asphalt road was tried in the United States as early as the mid-1980s. The most widely known use is for road replacement. This process involves a “train” of equipment that mills the existing asphalt concrete. Then the reclaimed asphalt is crushed to gradation and mixed with an engineered cold recycling emulsion and this mix is repaved as the new base layer, compacted to specified densities and readied for surface treatment; that is why asphalt plant equipment for sale is necessary to ensure proper method deliverance.
For best results, a mix design is formulated based on the characteristics of the pavement being recycled. This mix design determines the recipe for the emulsified recycling agent and any other additives that may be needed to bring the recycled mix up to the highest structural value possible.
