American Asphalt Recycling Solutions, Inc.
SELECTION: Visual Inspection must be done to rule out non-candidate roads. Random samples should be taken from candidate roadways. Samples are then processed to assure that it can meet minimum requirements for recycling. MIX DESIGN: Is created to assure the newly recycled pavement meets the specification and requirements for a serviceable asphalt pavement. Once the mix design is formulated pre-construction can begin. PRE-CONSTRUCTION:
Cleaning and spot repairs are required to ready the roadway for processing prior to construction. Once all the Pre-Construction is complete construction can begin. HEATING: Construction begins with heating the pavement with a series of 5 or more patented* radiant/convection furnaces to operating temperature and depth. This heating process limits the amount of damage done to the asphalt binder.
100% Recycled Asphalt Pavement Saves Money, Time and Natural Resources
REMOVAL: Spring-loaded tooling first cuts into the heated pavement to the required depth. The blades shave the dislodged pavement to a uniform cut. The augers then move the material into a central windrow for further processing. This windrow can be supplemented with new materials as required to establish grade and slope requirements. TACKING: The existing pavement is tacked where required. Even though the existing pavement is warm and will bond with a thermo-bond, in some cases there are areas that could use some additional bond which can be supplied as necessary with the Shaver's tack distribution wand at the rear of the machine.
MIXING: The heated rejuvenator is added proportionately by the computer prior to loading the raw materials into the 20' long heated asphalt plant. The plant temperature is held at 350°F to provide an environment for complete and thorough mixing. The materials are mixed in the plant for an additional 1-2 minutes depending on processing speed. PLACEMENT: The newly recycled mixture is then placed by a heated vibratory screed. Uniform distribution of the material is controlled by two augers. The material flow of each auger is controlled by a mechanical paddle.
COMPACTION: Is done by standard compaction equipment and principles to achieve a final surface.
