Patching Road Asphalt Cold Patch Micro Paving Wearing Courses Maintenance

    Patching Road Asphalt Cold Patch Micro Paving Wearing Courses Maintenance Micro Paving Cold Mix Asphalt is patented high technology and environment friendly product, uses eco-friendly cold mix processing and significant ultra thin overlay technology, micro overlay cold asphalt especially designed for construction and maintenance of wearing courses. Its paving thickness only require 0.7-1.2cm. Construction is quick and easy.

    Zhongtian pit repair technology meets the requirements of fast, timely and all-weather. With fast construction speed, easy operation and the advantages of construction in winter and rain and snow.

* Micro Paving seals small cracks and surface imperfections, waterproofs the surface, and protects the pavement structurure.
* Does not required heat in its application. Therefore, there is no time limit between production and application.
* A conventional primer or tack coat before application is not necessary
* Provides an attractive, smooth black surface which aids in lane delineation.
* The paving thickness is only 7 to 12mm, much thinner than traditional overlays. The very thin overlay is ideal where curbs and overhead clearances need to be preserved.
* Durable overlay fills ruts, preserves grade and curb reveal, and eliminates crowning and buildup.
* All season construction, not sensitive to climatic conditions, successful installation were carried out at temperatures from below 25 degree to above 50 Celsius degree
* Due to its unique properties of modified asphalt, the asphalt mixture has the pressure sensitive performance, the greater the volume of traffic, micro overlay bonded with the original surface more firmly.
* Safe Driving. High level of skid resistance. Reduces hydroplaning
* Noise reduction, antifogging, excellent resistance to water damage.
* Storage time can be 1 year, which allows you to use them for several different projects at different time
* Minimal disruption to traffic, business and residents. Accept traffic within 3 hours.
* The material is non-hazardous and environmentally friendly.

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.
2. Paving
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.
3. Compaction
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.
