The Road Shot Blasting Machine is the definitive dust-free solution for the continuous, automated surface preparation of concrete pavements, asphalt roads, airport runways, and steel bridge decks. Designed as a core workhorse for pavement treatment, it provides balanced cleaning and profiling performance across a wide range of horizontal surfaces.
This system delivers a consistent Sa 2.5 / CSP 3-6 surface finish while maintaining maximum daily output, offering a highly flexible platform for road contractors, waterproofing crews, and airport maintenance teams.
Designed for demanding jobsite environments, our Road Shot Blasting Machine offers a high-impact, dust-free alternative to traditional floor grinding and milling. It opens concrete capillary pores and creates superior mechanical anchorage on bridge decks, highways, and steel plates, ensuring maximum adhesion for epoxy, polyurea, and asphalt overlays.
Built with high-chromium alloy wear components and variable frequency drive (VFD) controls, the unit allows operators to precisely calibrate travel speed and blast intensity. Combined with an optimized abrasive recycling system, it keeps media consumption below 100g/m² while fully complying with strict OSHA environmental standards.

99.5% Dust-Free Closed-Circuit Recovery: High-performance pulse-jet filtration keeps dust emissions below 10mg/m³, fully compliant with strict environmental and OSHA standards.
Consistent Sa 2.5 / CSP 3-6 Surface Profiling: High-velocity abrasive impact creates ideal surface roughness on concrete pavements, airport runways, asphalt, and steel bridge decks in a single pass.
Heavy-Duty High-Chromium Alloys: Direct-drive blast wheel impellers, control cages, and housing liners are cast from wear-resistant high-chrome alloy for maximum service life.
Precision Siemens PLC & VFD Control: Variable frequency drive allows seamless adjustment of travel speed and abrasive flow, preventing over-blasting and ensuring uniform coverage.
One-Person Self-Propelled Operation: Walk-behind design with flexible maneuvering makes it easy to operate around obstacles, expansion joints, and tight jobsite spaces.
Low Abrasive Consumption: Optimized separation system reclaims clean steel shot for continuous recycling, keeping media consumption below 100g/m².
CLEANING RESULT: Sa 2.5 (High Efficiency)

Yes. By adjusting the travel speed and blasting intensity via the VFD control, operators can easily switch between gentle concrete profiling and aggressive steel deck descaling.
The blast head seals against the pavement. Steel shot and debris are pulled into the separator by high vacuum; clean shot is recycled while fine dust is trapped in the pulse-jet filter bin.
A grinder uses diamond discs that smooth or glaze the surface. A shot blaster impacts the surface at high speed, opening concrete capillary pores and creating an ideal CSP 3-6 profile for maximum adhesion.
By using the automated abrasive replenishment system and keeping the Siemens PLC settings optimized for the specific surface hardness, the machine consistently maintains the target finish.
