Abstract: A heatless method of manufacturing cold asphalt, such as for road repair and construction, that may be easily produced at or near a job site. The method includes the introduction of RAP (recycled asphalt and a small amount of new asphalt), additive oil, and optional sand (silicates and/or sieved RAP) and lime (limestone powder) into mixing apparatus. The mixing apparatus includes two hoppers: one hopper for RAP and a second hopper for RAP or sand; a live feed for additive oil; and another for optional lime; conveyors; and a controller that is programmed to determine the correct proportion of RAP, optional sand, oil, and optional lime. The invention also includes a product-by-process in which cold asphalt mix is produced. 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.

Abstract: A heatless method for producing cold asphalt at a job site, such as for road repair and construction. The method includes mixing apparatus having one hopper for receiving screened RAP (recycled asphalt and a small amount of new asphalt), a live feed for additive oil, and another for optional lime (limestone powder), conveyors in which to convey the RAP, 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), additive oil, and optional lime The mixing apparatus is compact in size to mount atop of a wheeled trailer for use at a construction site. The end product does not quickly harden, like that of hot asphalt, and is essentially non-toxic with little to no VOCs and HAPs, and is produced, stored, used, and compacted at ambient temperature.

Abstract: 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.
