| Infrared restoration has proven to be the finest method available for repairing the majority of asphalt defects. It, however, is not the solution for all defects. Asphalt defects caused by base failures must be repaired by removing and replacing the existing material from the sub base up through the wear course. |
| THE PROBLEM |
THE SOLUTION |
|
When using infrared for repairing asphalt there are two important concerns that must be addressed
FIRST: The existing asphalt pavement that will be recycled has aged over time. Exposure to the sun and the elements over time oxidized the light oils component in asphalt.
SECOND: During the infrared heating process, as the temperature of the asphalt is increased to above approximately 375 degrees Fahrenheit, the oxidation of light oils are accelerated. It is also important to know that at around the 500 degree mark, asphalt will burn (coke) rendering it useless for recycling.
|
Maltenes are the light oil component of asphaltic cement (AC). Asphaltenes are the black solids that provide the gluing characteristics of AC. The maltenes are the medium through which the asphaltenes are dispersed.
The engineers from the Asphalt Institute recommend using a maltenes rejuvenator. The rejuvenator that we recommend using in conjunction with the Infrared Restoration Process is a product called Cyclogen LE. Cyclogen is a maltenes rejuvenator. Therefore, by adding Cyclogen to the asphalt after it has been heated you are overcoming the two possible causes of problems. You are replacing the portion of the asphalt that has been compromised by either natural aging or the heating process.

| INFRARED RESTORATION OF UTILITY OPENINGS |
| BENEFITS |
DECISION MAKER |
| ● |
Seamless Repair - Prevents water from infiltrating. |
| ● |
Settlement - Because the infrared restoration is made 90 days after the repair is made future settlement is unlikely. |
| ● |
Cost - Infrared restorations are much less expensive then mill and replace repairs. |
| ● |
Convenience - Infrared restorations are quicker to install and much less disruptive to traffic. |
| ● |
Customer Satisfaction - Only infrared restoration returns the street to "like new" condition. It is ideal for moratorium roads. |
|
| ● |
Typically each client dictates how they want their driveway, streets, parking lots, etc. restored after being opened by a utility company or contractor. |
| ● |
Utility companies benefit by being allowed to open streets that are on a moratorium list. |
| ● |
Customers enjoy a much improved level of customer satisfaction. (Less complaints and call backs) |

BENEFITS OF
INFRARED RESTORATION
vs
CONVENTIONAL REMOVE & REPLACE ASPHALT ARE:
|
| FASTER |
25 minute repair means minimal disruption to traffic. |
| NO COLD JOINTS (no way for the water penetration) |
Prevents future entryway for water (future pothole) |
