Apparatus for producing cold
asphalt, such as for road repair and construction, that allows cold
asphalt to be easily produced at or near the job site. The apparatus includes at least one hopper for receiving screened
particulates, an optional second hopper for granular materials, e.g., sand, a
live feed for additive oil, and another for optional
lime, conveyors in which to convey the granular and screened
particulates, oil, and optional
lime to a mixer. The mixer is controlled through a controller that is programmed to determine the correct proportion of RAP (recycled
asphalt and a small amount of new asphalt), optional sand (silicates and / or sieved RAP), additive
hydrocarbon oil, and optional
lime (limestone
powder). The apparatus may be permanently installed to create a cold asphalt manufacturing
plant or placed on a trailer for use at a construction site. The invention further includes a heatless method of manufacturing cold asphalt through the introduction of RAP, additive oil, and optional sand and lime into the apparatus and a product-by-process in which cold asphalt mix is produced through the process claimed in the method. The end product is essentially non toxic with little to no VOCs and HAPs, has long shelf-life, and is produced, stored, used, and compacted at ambient temperature.
