Deep Recycling at its best
|
CONCEPT
Dustrol's Mobile Asphalt Recycling System, or MARS, is an efficient process used to repair and rehabilitate deteriorated bituminous streets and
highways on-site with specialized equipment.
PROCESS
This process allows for 2" or more to be heated, rejuvenated and placed.
BENEFITS
This recycling discipline provides a low-cost maintenance strategy for removing cracks, ruts, and low areas by utilizing existing asphalt
pavement for in-place rehabilitation. Flexibility and quality are restored to the asphalt material and the pavement is prepared for other surface treatments.
SAVINGS
Surface recycling allows the available dollars to be spread over more square yards of pavement maintenance areas. Increased costs of
maintenance work make this process a very desirable alternative in a roadway repair program.
COMMUNITY
Highly efficient equipment and improved methods of pavement rehabilitation allow for a recycled street to be completed and opened to
traffic with only a few hours delay. Although highly visible to the public, the process is fast and presents only minor inconvenience to motorists.

How it Works
| 1. Dustrol's MARS process begins with two or more custom-made, propane-fueled
preheaters. |
2. The next heater in the train is equipped with hydraulically controlled milling drums which windrow the top 1" of material. The milling
heads are capable of milling 15' wide and 1"+ deep. |
| 3. The tunnel heaters begin heating the underlying pavement while maintaining the temperature of the windrow. |
5. The windrow of recycled material enters the radiant heating oven prior to final mixing. |
| 6.The two milling drums on the main unit mills additional depth and adds emulsion. Emulsion is controlled by an onboard computer. Depth is
controlled by automatic grade sensors |
8.The material is then spread and paved by a vibratory screed to the specified width. |
| 9. The reprocessed asphalt is then compacted using conventional rolling methods. |
10. Dustrol's Mars machine combines many of these operations to minimize disruption to traffic. |
|
11. Finished Material after laydown and compaction. The road can be opened to traffic after a cool off period similar to an asphalt paving
operation. |

SUMMARY
By utilizing our process you can expect the following benefits:
-
less impact on the environment
-
reduced cost allows more miles of roadway to be maintained.
-
Minimal impact on traffic.
-
Process is independent of other processes, allowing a more flexible schedule
