All-weather suitability enhanced cold patch

All-weather suitability enhanced cold patch

Features:

1. Strong temperature resistance: The applicable temperature of the cold patching material is -20°C~50°C (at ambient temperature), and it can repair pits in time under the harsh environment of rain, snow, and humidity;

 

2. High strength: No need to equip special tools and equipment, nor special technology, just clean up the pits to be repaired (the effect is better if the bottom surface is flat and hard ballast on the side), put in cold patching materials, and use It can be opened to traffic after being rolled by a road roller several times or compacted with an impact rammer.

 

3. Stable performance: The cold patching material has strong anti-aging performance, and the service life of the repaired pits is more than 10 years, and it is not easy to produce cracks and other bad phenomena. It can be stored in the open air for 6-12 months, and can also be packaged and stored for more than one year.

 

4. Strong cohesive force: The cold patch material has strong cohesive properties and can be quickly and well combined with asphalt concrete, cement concrete, mesh surface, and metal materials, and will not cause loosening, falling off, cracking, and other diseases after patching, the vehicle will not take away the cold material. Both the maintenance quality and the repair effect can meet the maintenance standard requirements, and the quality is stable.

 

5. Environmental protection requirements: There is no smoke, no waste, no peculiar smell, no dust during the production and use of cold patching materials, the additives do not contain toxic substances, the materials are insoluble in water, and will not pollute the air, environment, and groundwater, which is conducive to environmental protection. Meet environmental protection requirements.

 

6. Cost saving: no need for heating and stirring, it can be taken according to the actual usage, and the remaining materials can be used continuously without wasting.
7. Strong flexibility: suitable for acidic and alkaline aggregates; due to the difference in regional climate, we can provide corresponding product grading and additive formulas according to the needs of customers.

 

8. Strong water resistance: It can be repaired on rainy days during construction.

 

9. Simple construction: Usually, it is especially suitable for daily repair of small-area diseases such as tiny potholes. It can be repaired immediately when it is rotten. It is not limited by large-scale mechanical equipment and only needs small tools such as trimming and pressing. Preventive maintenance of pavement.

 

10. Simple process: The maintenance operation process is simple and easy, no heating or stirring is required during repair, and it can be used at any time without wasting materials. After repair, traffic will be opened, greatly relieving the traffic pressure on high-grade highways caused by road repair construction.

scope of application

It can be widely used in roads, bridge pavements, parking lots, airport runway paving pipeline trenches, large, medium, and small living quarters, industrial parks, bridgehead joints, construction machinery, and repair of contact parts.

Cold patch construction:

Pit repair (edge trimming, slag removal, blowing, oiling) → filling leveling (layered packing, shaping) → compaction (plate compactor, aluminum plate, small road roller, non-highway roads can command driving to roll)

 

1. Repair potholes:

Step 1: Clean up the pit. When the pit is large, it is better to have hard ballast around and on the bottom, which is more conducive to the maximum bonding of the cold patch material.

Step 2: Fill the pit with the appropriate amount of cold filler. If the depth of the pit is more than 8cm, it needs to be compacted in layers. The virtual height of the filler is determined according to the degree of compaction, which is generally 1-2cm.

Requirements: The repaired surface is smooth, flat, without wheel marks, and without loose edges. The density is over 95%.

 

1. Emergency repair of the large area of road surface:

If the road surface is damaged in a large area or the pipeline is broken and the road surface is excavated, the roadbed should be cured first, and the degree of compaction should be above 93%, which should have the corresponding bearing capacity. Then pave and compact in layers, specially designed for this purpose with a coarse grading cold patch, in this case, a plate compactor or road roller is required for compaction.

 

Various parameters

1. Composition of cold-patch asphalt mixture: Cold-patch asphalt mixture is made by mixing modified asphalt and stone.
2. Physical state: black granular solid.
3. Specifications: 03#, 05# mixture, that is, the national technical specification LB-10, LB-13 mixture
4. Packaging: composite woven bag packaging
