Roto-Mill Inc. is involved in the process known as Expanded Asphalt Stabilization in the Ontario market.
Although the process is not new, the development efforts made by Roto-Mill Inc. over the past three years has helped us to become an innovative leader in a technology that is rapidly becoming accepted as a cost effective method to producing a deep strength road base.
Briefly, the process calls for the full depth pulverization of old asphalt pavement (or even gravel) roads. The road is then graded and compacted so that it is near final profile. Once the initial pulverization is complete, the area is then re-pulverized with the resulting material injected with a performance graded asphalt cement (AC). The roadway is then compacted using vibratory and rubber tired rollers to a minimum of 96% of the laboratory compacted density.
The process for performing this procedure is essentially the same for each project, however each roadway will have its own mix design and specifications (for asphalt depth) that will call for specific adjustments to the existing road base, i.e. the addition of aggregates. All laboratory work is done by a qualified engineer and is extremely important to the final results.
Roto-Mill Inc. prides itself on having the expertise to improve the technology so that a consistently high quality product is achieved.
If you have any questions or require more detail on the Expanded Asphalt process, we would be happy to address any and all inquiries.
