Asphalt
Mobile handling for hot-mix asphalt and reclaimed asphalt pavement at plants and paving sites.
SANTO supplies mobile conveying, stacking and loading equipment engineered for asphalt — from receiving and stockpiling to reclaim and load-out. The notes below cover the properties that matter, the problems that typically appear on site and the machines we recommend.
Why Mobile Conveying Suits Asphalt
Asphalt is a hot (150–180 °C), cohesive bituminous mix, while RAP is crushed, recycled pavement. The wheeled mobile conveyor links paver and plant with clean, low-segregation transfer that protects mix temperature.
- Short transfer paths preserve mix temperature to the paver
- Low drop height limits aggregate segregation in the mat
- Mobile conveyors follow the paving train for continuous feed
- Easy cleanup with release agents keeps bitumen from sticking
- RAP handling feeds recycle directly back into the plant
Physical Properties and Handling Behaviour
The table below summarises the properties that decide belt specification, chute geometry and stacking method for this material. Values are typical ranges — actual figures vary with source and moisture content, so we test your sample before finalising a design.
| Property | Typical Value / Handling Impact |
|---|---|
| Temperature | Hot mix 150–180 °C; RAP ambient |
| Bulk density | 2.2–2.4 t/m³ for dense hot mix |
| Cohesion | High when hot — tends to stick and segregate |
| Angle of repose | Steep when hot; flows poorly when cooled |
| Handling note | Minimize segregation and preserve temperature |
Handling Challenges with Asphalt — and How SANTO Solves Them
Hot mix cools and segregates quickly; long drops separate coarse stone from fines and chill the mat. Bitumen also coats belts and frames, making cleanup hard.
SANTO mobile conveyors keep transfer short and low to retain temperature and grading, and use release-agent-friendly surfaces for quick cleanup. The wheeled train follows the paver, feeding RAP and mix without fixed plant.
- Keep transfer short and low to retain heat and grading
- Use release-friendly surfaces for bitumen cleanup
- Follow the paving train for continuous, mobile feed
Recommended SANTO Equipment
For asphalt we most often supply the machines listed below. Each can be configured with the belt width, boom length and drive power your tonnage requires, and each is available on wheeled, tracked or crawler chassis.
- Wheeled Mobile Conveyor — configured for asphalt duty
- Tracked Radial Stacker — configured for asphalt duty
- Feeder Mobile Stacker — configured for asphalt duty
- Grasshopper Conveyor — configured for asphalt duty
Typical Stockpiling and Loading Setups
A well-planned asphalt yard keeps receiving, stacking and reclaiming on separate paths so trucks never queue behind a loader. In the most common layout, a mobile conveyor receives from the tipper or hopper and feeds a radial telescopic stacker that builds a layered stockpile, while a second conveyor reclaims to the loading point.
- Receiving: hopper or direct truck discharge into a mobile conveyor
- Stacking: radial or telescopic stacking to build layered, drainable stockpiles
- Reclaim: front-end loader feeding a mobile conveyor, or direct reclaim conveyor
- Load-out: conveyor to truck, wagon, barge or vessel hold
Frequently Asked Questions
How is asphalt temperature preserved?
Short, low transfer paths minimize heat loss between plant, silo and paver, protecting workability of the mat.
Why does segregation matter in asphalt?
Separating coarse stone from fines weakens the pavement; low drop height keeps the gradation intact.
Can mobile conveyors handle RAP?
Yes. Crushed reclaimed pavement is fed straight back to the plant or stockpile, supporting recycle content.
