Packaging asphalt cold patch can be challenging because the material is sticky, heavy, and difficult to meter consistently. This semi-automatic asphalt cold patch bagging system was set up and dialed in to fill 50 lb open-mouth plastic bags, but this type of system can be configured to package bags ranging from 20 lb to 110 lb, depending on the material, bag style, and production requirements.
The system includes an open mouth bagging machine, auger-fed bagging scale, hot air bag sealer, bag closing conveyor, bag kicker, incline bag flattener, and end-of-line palletizing support equipment. Together, this equipment creates a controlled packaging process for difficult-to-flow paving, repair, and road maintenance materials.

Asphalt Cold Patch Packaging: Sticky and Difficult to Handle
Asphalt cold patch is first mixed at a separate facility, then transported to the packaging area for bagging. Because the material can be sticky and difficult to handle, the packaging line needed to meter product accurately, reduce manual handling, form and seal plastic bags reliably, and prepare each finished bag for palletizing.
For this project, the system was designed around 50 lb bags of asphalt cold patch. However, similar open-mouth bagging systems can often be configured for other bag weights in the 20 lb to 110 lb range. This flexibility is useful for companies that package product for retail, contractor, municipal, or industrial customers.
Open Mouth Bagging Machine and Bagging Equipment Solution
The installed open mouth bagging system uses a skid steer-fed surge hopper, auger conveyor, bagging scale, pneumatic bag clamp, hot air bag sealer, bag closing conveyor, bag kicker, incline bag flattener, and gravity roller accumulation table.
The result is a semi-automatic cold patch packaging line that helps operators fill, seal, flatten, and palletize bags with consistent control. The equipment layout also supports a practical workflow for operations where material is loaded into the system using a skid steer loader.
Bagging Equipment Used in the System
- Surge/feed hopper for loading via skid steer loader
- Auger conveyor
- Open mouth bagging machine
- Bagging scale with fast/slow fill control
- Bag clamp with foot pedal activation
- Hot air bag sealer
- Bag closing conveyor
- Bag kicker
- Incline bag flattener
- Gravity roller accumulation table
Best Applications for This Type of Bagging System
This type of bagging equipment is well suited for asphalt cold patch, cold mix asphalt, blacktop repair mix, pothole patch, road patch material, driveway repair mix, bituminous repair material, asphalt repair mix, pavement repair materials, and aggregate/asphalt repair blends.
It may also be a good fit for other sticky, dense, granular, or difficult-to-flow materials that need to be packaged in open-mouth plastic bags.
How the Asphalt Cold Patch Bagging System Works
After the asphalt cold patch material arrives in the packaging area, it is dumped into storage bunkers. A skid steer loader transfers product from the bunker into the surge hopper. From there, an auger located at the bottom of the hopper conveys material up into the bagging scale.
The digital bagging scale controls both the product cutoff gate and auger speed. The operator places an open-mouth plastic bag onto the open mouth bagging machine spout and presses a foot pedal. This activates the bag clamp, secures the bag in place, opens the internal cutoff gate, and starts the auger in fast-fill mode.
For this project, the fast-fill cycle runs until approximately 38 lb of material has entered the bag. The auger then automatically switches to slow-fill mode to improve accuracy as the bag approaches its final target weight. Once the scale reaches 50 lb, the auger stops, the product gate closes, and the filled bag is released onto the bag closing conveyor.
For other applications, the scale controls can be adjusted for different target bag weights within the 20 lb to 110 lb range, depending on the product, bag dimensions, and system design.
Hot Air Bag Sealing, Bag Flattening, and Palletizing
Once the filled bag is released, the operator reforms the top of the bag, leans it against the conveyor back rail, and guides it through a hot air bag sealer. Because asphalt cold patch can be sticky, the line uses a flat back rail rather than a V-belt-style conveyor. This helps keep the cold patch packaging equipment simple and well suited to the application.
After sealing, the bag travels along the conveyor to a bag kicker. The bag kicker knocks the bottom of the bag out and onto an incline bag flattener, which shapes and reforms the package for more uniform stacking.
At the top of the incline bag flattener, bags discharge onto a gravity roller accumulation table. From there, an operator picks up each finished bag and places it onto a pallet in the required pattern.
The Result
The finished asphalt cold patch bagging system provides a controlled, operator-friendly packaging line. This specific system was set up and dialed in for 50 lb bags, but the same type of open-mouth bagging equipment can be configured for 20 lb to 110 lb bags in similar applications.
By combining auger-fed weighing, fast/slow fill control, positive bag clamping, hot air bag sealing, bag kicking, flattening, and manual palletizing, the line supports accurate fills and consistent package presentation.
This project shows how the right combination of open mouth bagging equipment, bag sealing equipment, bag flattening, and palletizing support can create a reliable packaging system for difficult-to-handle paving and repair materials.
Future Automation Upgrades for Asphalt Cold Patch Bagging
For future upgrades, additional automation could be added to further reduce labor requirements. A small-footprint bag palletizer would allow the line to automatically stack finished bags in the required pallet pattern while minimizing the amount of floor space needed.
This type of palletizer can also be configured to place an empty pallet into the bag stacking zone and apply a slip sheet before stacking begins. These features would help streamline the end-of-line process, improve palletizing consistency, and reduce the amount of manual handling required from operators.
