1. Surface pretreatment before construction
Cleaning: clean the surface dust and debris, to ensure that "Go Green" and the original pavement can be bonded firmly.
Weather Conditions: Micro paving can be constructed in the temperature above 0℃, convenient and quick.
The products are placed on the road using a thin layer paving machine without require heating or apply any tack coat on its application. It is a cost-effective pavement preservation technique.
Micro paving recommended professional road paver/roller for paving, the asphalt paver need to be able to complete 0.7-1.5cm thin layer paving. For small area, it should use manmade spreads out. And making sure that it is the smae everywhere.
1) Rolling process of micro paving cold mix asphalt is the same way as conventional asphalt.
2) When the material has been laid, either by hand or machine, it is recommended to compact the surface as soon as possible. Compact 4-5 times to guarantee the compaction without crashing aggregate.
4. Accept Traffic
Close traffic completely after construction, open the traffic after 3 hours till pavement surface is drying and hardening.
Zhongtian Patching Road Asphalt Cold Patch Micro Paving Wearing Courses Maintenance can be widely used in municipal roads, general roads, highways, parking lots, airport runways, tunnel damage of road asphalt concrete and cement concrete pavement, ruts, municipal road tunneling, repaired pavement, bridge expansion joints, heavy load pavement , repair and maintenance of road traffic and special road.
