MR² - AB Method

Outline

The MR²-AB Method is used in milling, overlay, and re-pavement work to eliminate level differences that arise when the manhole is exposed up to the binder course. To ensure safety, this technique first involves removing the manhole cover, performing a temporary repair, and then replacing the manhole cover after the surface course is completed. The pavement around a manhole is vulnerable to damage due to insufficient compaction. This technique prevents insufficient compaction, which can occur because of factors like temperature drops, because the pavement around a manhole is constructed with a cold mix. MR² Hybrid is used as the surface course material.

Features

1. The Manhole Remover operates with low noise and minimal vibration.
2. Since this technique eliminates level differences around manholes, it reduces noise and vibration from through traffic.
3. Since this technique eliminates level differences around manholes, this technique ensures pedestrian safety.
4. This improves the final quality of the surface course installation by enhancing flatness and ensuring sufficient compaction density.

Applications

• Repairs in areas where noise and vibration need to be minimized, such as during nighttime and in residential areas
• Repairs in high-traffic areas and areas where road closures are not possible
• Repairs in areas where roads need to be reopened to traffic quickly
