Asphalt Cold Patch is high‑performance ready‑to‑use asphalt repair material for fast, economical pavement maintenance. No heating or special equipment is required to fix potholes and damaged asphalt surfaces rapidly with little traffic interruption. Applicable to highways, municipal roads, parking lots, bridges, airports and industrial zones, it delivers strong adhesion, superior weather resistance and durable repair performance under both hot and cold climatic conditions.
Explore the Process
A streamlined workflow engineered for consistency, efficiency, and premium quality.
Formulation design: Develop formula and production process according to product characteristics
Laboratory test: Lab-scale trial and substrate performance verification
Scale-up validation: Pilot production of 1-2 tons; re-optimize formula if performance deviation occurs
Sample adjustment: Customer sample referencing → lab formulation tuning → finalize production formula → minor adjustment
Technical handover: Compile technical documents and brief production & QC teams
Incoming materials: Asphalt, limestone aggregate, cold-patch additive, packaging bags
Inspection procedure: Standard testing; qualified for warehouse entry; non-conforming items for rework / return / conditional retention upon factory manager approval
Material handling: Forklift and overhead crane for unloading and intra-plant transfer
Bucket elevator acts as the core feeding unit, and the wheel loader delivers materials to the 3‑bin weighing scale.
Cumulative weighing is applied: aggregate No.1, No.2 and No.3 are loaded sequentially without intermediate discharge to hit the formula‑set target total weight.
The entire feeding‑weighing process is supervised by the on‑site instrument operator.
Full‑process controlled by the operation console; QC staff supervises the input of all formula parameters.
Asphalt is electrically transferred out from the storage tank; cold‑patch additive is prepared inside the reaction kettle and then conveyed to the mixing tank.
The mixer completes thorough blending to obtain homogeneous mixture of aggregate and cold‑patch additive.
Mixed material flows into the homogenizer for homogenization to stabilize batch‑to‑batch consistency.
Quantitative filling is completed by the bag‑packing machine, following standard specification of 25±0.5 kg per finished bag.
The pneumatic butterfly valve cooperates with the air‑flotation device to prevent material buildup and discharge‑port blockage during regular operations.
Automatic palletizing is realized by robotic palletizer, which supports preset program loading and adopts password‑protected operation to avoid unauthorized parameter modification.
Qualified finished products that have passed full QC inspection will be mechanically conveyed and safely transferred into the finished‑goods warehouse for stock storage.
- Mandatory test items: Adhesion grade, penetration strength, Marshall stability (25 ℃), residual Marshall stability, visual appearance.
- On-site patrol inspection; non-conforming products disposed by workshop upon factory manager’s approval.
- Weekly summary for standard and process revision.
