Proven innovative One Pass Chip Sealing
Smarter, safer and environmentally better
One Pass Chip Sealing concept
The one pass system is the single most important innovation to hit the bitumen sealing industry since it’s inception. Ashpave's Chip Sealer is a single operator vehicle which sprays the binder and spreads the aggregate in one forward pass at pre determined calibrated application rates that are modulated and controlled by an on board computer.
The One step in situ emulsion surfacing using 4% polymer modified high bitumen content emulsion applied at 85°C.
With modern emulsions it is possible to work in wider range of climate and conditions and higher than previously possible spray rates can be applied.
High bitumen content polymer modified emulsion is the future of sealing in Australia and now is the time to embrace proven technology and show a willingness to protect our environment.
Computerised
Computer controlled spraying and spreading ensures that we can dial in the machine to meet exact surfacing design with consistent quality of the job, from one end to the other.
A computer road visualization system gives the machine the ability to place seal on a road in all manner of sizes from road lane width 3.1 meters down to 200mm. With the vehicle’s ability to spray and spread in this range it is possible to cover all manner of configurations on a road lane on the run; tapers, strips, wheel tracks.
This gives the ability to maintain a road surface thoughout its life span. The option of pinpointing surface degradation in bulk. Road repair and or re-seal budgets can cover a bigger slice of a road network.

Complete chip sealing operating system
We have designed and built a specialized emulsion storage tanker and fast load conveyor system to enable quick re load of the chip sealer's aggregate bin and emulsion tank to maximize daily production for our customers.
With this system it is now possible to have daily outputs of road surfacing maintenance, never before seen in Australia with a single machine.

Better for the environment
• Reduced energy waste
• Less petroleum product ,no cutters or adhesion agents required
• Significantly less 'Greenhouse Emissions' 85°C vs 180°C
• Substantially less environmental damage with no kerosene leaching into the environment
Far safer working environment
• No uncovered binder
• Substantially less heating required, spraying temperature 85°C vs 180°C
• Less overhead hazard risk
-
Less traffic hazard risk. No reversing spreader trucks. No operator stress
• Greatly reduced risk of burns, explosion and inhalation of harmful fumes
• The process allows for a mobile work site with traffic control measures similar to line marking to be employed and reduce disruption
Better for public safety
• The aggregate is applied to the binder within 1 sec which eliminates hazards to pedestrians or vehicles coming into contact with uncovered binder
• Safer way of achieving job specifi-cation with less risk of the general public being exposed to high temperature bitumen products & toxic fumes
• Far less risk of vehicles or pedestrians being exposed to uncovered binder and reversing tip trucks spreading aggregate
• Far less traffic disruption
