Slippery roads. Faded markings. Worn runways. A road shot blasting machine delivers the solution. No chemicals. No water. Just high-speed steel shots that restore friction, remove rubber, and prepare surfaces for new coatings. For highways, bridges, and airport runways, our road shot blasting machine helps you make surfaces safe again.
YG Machinery offers reliable road shot blasting machines for asphalt and concrete surface preparation.
What Is a Road Shot Blasting Machine?
A road shot blasting machine is a self-propelled surface preparation device that propels steel shots at high speed onto asphalt or concrete surfaces. The impact removes contaminants, old markings, rubber deposits, and weak surface layers. The machine recovers and reuses the steel shots while a dust collector captures dust and debris.
Suitable for:
- Highway friction restoration
- Road marking removal
- Airport runway rubber removal
- Bridge deck surface preparation
- Tunnel pavement maintenance
- Municipal road renovation
Advantages:
- Restores surface friction quickly
- No water or chemicals needed
- Dust-free operation with integrated collector
- Does not damage pavement structure
- Steel shots recycled automatically
- Works on asphalt and concrete

Working Principle of Asphalt Shot Blasting Machine
Step 1: Steel Shot Loading
Steel shots are loaded into the storage hopper. The machine controls the flow rate.
Step 2: High-Speed Propulsion
The blasting wheel motor rotates at high speed. Steel shots are thrown through the directional sleeve at the working surface.
Step 3: Surface Impact
Steel shots strike the surface at high speed. Contaminants, rubber, markings, and weak layers are removed. Surface becomes rough and clean.
Step 4: Recovery and Separation
The rebound chamber collects steel shots, dust, and debris. The separation system separates reusable steel shots from waste.
Step 5: Dust Collection
Dust and fine particles are drawn into the dust collector through the connection pipe. Filter elements capture dust. Clean air is released.
Step 6: Steel Shot Recycling
Clean steel shots return to the storage hopper. The cycle continues automatically. Minimal steel shot loss.
The entire process is continuous. No stopping. No water.
Application of Asphalt Surface Preparation Machine
Highway friction restoration – Asphalt surfaces lose friction over time. Shot blasting removes the polished surface layer. Restores texture and skid resistance. Reduces accidents on wet roads.
Road marking removal – Remove old painted markings and thermoplastic lines. Clean surface for new markings. Faster than grinding.
Airport runway rubber removal – Aircraft tires leave rubber deposits on runways. Shot blasting removes rubber buildup. Restores runway friction for safe landings.
Bridge deck preparation – Clean and roughen bridge decks before waterproofing. Improves adhesion of waterproof membranes. Extends bridge life.
Tunnel pavement maintenance – Tunnels need good friction for safety. Shot blasting restores skid resistance in enclosed spaces. Dust collector keeps air clean.
Municipal road renovation – Prepare city roads for resurfacing. Remove old coatings and contaminants. Clean surface for new asphalt.
Steel bridge deck cleaning – Remove rust and old coatings from steel bridge decks. Prepare for anti-corrosion primer.
Parking garage floor preparation – Clean and roughen concrete floors before new coatings.
Working Conditions for Highway Shot Blasting Equipment
Surface conditions:
- Unevenness: <10 mm
- No standing water, surface must be dry
- Slope: <25°
Temperature:
- Ambient: -20°C to 60°C
- Steel surface temperature: more than 3°C above dew point
Humidity:
- Steel shot blasting: relative humidity ≤90%
- Concrete shot blasting: relative humidity ≤95%
Altitude:
- 0 to 3000 meters
Weather:
- Do not operate in rain or snow
Following these conditions ensures optimal cleaning results and equipment longevity.
Customer Case – Runway Rubber Removal at Regional Airport
A regional airport in Southeast Asia needed to remove rubber deposits from their runway. Aircraft landings had built up a thick rubber layer over several years. Friction levels had dropped below safety standards. The airport could not close the runway for more than 48 hours.
The maintenance team used a YG-850 road shot blasting machine. The 800mm working width covered the runway quickly. The machine removed rubber and restored surface texture in one pass. The integrated dust collector captured all dust. No runway contamination.
The 48-hour window was respected. Friction levels returned to standard. The runway reopened on schedule. The airport now uses the same machine for runway maintenance every six months.
The maintenance supervisor said: “The YG shot blaster restored our runway friction in half the expected time. No dust on adjacent areas. No runway closure extension. We will use this for all runway maintenance.”
FAQ
Q: What surface profile does it create?
A: The profile depends on steel shot size, flow rate, and walking speed. Adjust these parameters to achieve the desired roughness.
Q: Can it remove thick epoxy coatings?
A: Yes. Multiple passes may be needed for thick coatings. Use larger steel shots for faster removal.
Q: How long do steel shots last?
A: Steel shots can be reused many times. Replacement depends on surface hardness and working hours.
Q: Is dust a problem during operation?
A: No. The integrated dust collector captures dust at the source. The work area stays clean.
Q: What surfaces can it work on?
A: Asphalt, concrete, and steel surfaces. Change steel shot size based on surface material.
Q: Can it work on wet surfaces?
A: No. Surfaces must be dry. Wet conditions cause steel shots to stick and block the system.
Q: What is the cleaning efficiency?
A: YG-270: ≥180 m²/h. YG-550: ≥400 m²/h. YG-850: ≥600 m²/h (concrete surfaces).
