Asphalt Mixture/Asphalt Patching Material

 I. Cold Patch Product Introduction:

Road maintenance departments typically use hot-mixed asphalt for patching road surfaces. However, due to factors like weather, temperature, size and quantity of potholes, and the extent of damage, hot patching cannot always be timely, especially for winter potholes. This leads to increased damage, not only wasting repair materials but also affecting traffic flow and reducing the lifespan of the road.

Sun Jian Xingye BrandCold patch material is processed using a special method to modify asphalt, which imparts the asphalt with its adhesive, pressure-sensitive, and viscoelastic properties. After proper compaction, it can adhere to the repair area for a long time without falling off.Cold patch material, with its numerous advantages such as the ability to repair road surfaces under various conditions, ease of operation, high-quality repairs, long storage life, and cost savings, has been widely applied for road surface repairs in various provinces and cities, and is increasingly recognized and welcomed by road maintenance departments.

Two,Characteristics of cold makeup material:

1Type Repair Material
Wide temperature range applicable for cold patch materials; can be used in-30℃Please provide the Chinese content to be translated.40℃Applicable between seasons, construction can be carried out regardless of rain, snow, or sunshine.

2Installation is simple.
Shunjian Xingye BrandWhen using cold patch materials for road pothole repairs, there is no need for adhesive oil. The materials can be taken as needed without heavy construction machinery. Depending on the specific repair situation of the road, impact compaction, manual compaction, or tire rolling can be used. Moreover, the area patched with cold patch material does not require traffic closure and can be reopened to traffic immediately, significantly reducing traffic pressure caused by road repair construction.

3Excellent quality in repairs
Cold patch materials have strong cohesion, making the repaired holes less prone to peeling and cracking, and do not require repeated repairs.

4Low repair cost
When using cold patch materials, the application is not affected by weather conditions, the size and quantity of the holes, and no heating or stirring is required during the repair process. Materials can be used as needed, and any remaining materials can be reused in subsequent repairs, thus preventing waste.100Utilization rate.

5Green and eco-friendly
The production and use of cold patch materials do not generate dust or black smoke, and the finished product is not soluble in water, thus preventing air and groundwater pollution, which is beneficial to environmental protection.

6Easily stored
Sealed bags of finished products can be stored for up to two years at room temperature without clumping.

Three.Shunjian Xingye brand Application Range of Cold Filling Material:

1This product is suitable for repairing and maintaining potholes and rut marks on highways and airport runway pavements.

2Suitable for repairing and maintaining road surface potholes on general highways and municipal streets, excavation pits, road restoration after underground pipeline installation, around manhole covers, small shallow holes in front of warehouses, and more.

3Suited for bridge expansion joints, heavy-load road and bridge junctions, high-traffic road curves, and special surface repairs.

Four,Cold Patch Application Method:

⒈Clearing Pits

General repairs should clean up the gravel and debris around the hole to be repaired, ensuring no mud, ice blocks, or other杂物 are present inside the hole. For repairs on highways and municipal road excavation projects, the repaired holes or trenches should have neat edges, and the debris should be removed until solid, firm surfaces are visible.

⒉Fill the gap:

Fill the hole with enough cold patch material until the filler is above ground level.1.5cmLeft and right, highway and general road repair, the material input amount can be increased20% or10About % full. After filling, the depression should be higher than the surrounding road surface and curved.

As the road surface pit damage thickness is5cmAt this point, the filling work should be conducted for each3－5cmFor the first layer, fill and compact layer by layer.

⒊Compacted

After even distribution, select appropriate compaction tools and methods based on the actual repair environment, area size, and thickness. Examples include manual shoveling, manual tamping, vibrating plate compactors, flat aluminum plates, truck tires, rollers, or pavers, etc.

⒋Acceptance:

The repaired hole surface should be smooth, flat, and free of wheel marks. The surrounding area and corners of the hole should be well-compacted without any loose particles, and the compaction should typically reach:93Over % of the total.

Cautionary Notes

⒈During low-temperature construction, it should be placed5℃The inventory is stored in the above warehouse.24Conducted in childhood.

⒉When resurfacing a highway, ensure the perimeter and corners of the repair area are compacted thoroughly.

⒊Adopting a continuous repair approach in place of the traditional centralized repair method will yield economic benefits.
