Pothole repair in four steps

Jetpatcher Road Repair Machines range from 2.5 to 10 cubic yards of hopper capacity, with emulsion tanks to suit. They use a four-stage process for asphalt repairs. Stage 1 uses a high-volume, low-pressure blower to clear loose debris from the pothole. In Stage 2, the Jetpatcher coats the pothole with an asphalt emulsion that seals the hole and prevents further moisture damage. Stage 3 mixes aggregate with the asphalt emulsion, which is then blown into the hole. In Stage 4 a light layer of dry aggregate is applied to the patch, preventing it from sticking to tires before the emulsion is fully cured. The patch is now ready for traffic.

LiuGong

10-percent reduction in fuel consumption

LiuGong says its new 915D excavator boosts work efficiency by 10 percent while reducing fuel consumption by 10 percent compared to its predecessor. The unit’s smart engineering starts with its Computer Aided Power Control System (CAPC), which LiuGong says automatically and continuously matches hydraulic output to ever-changing workloads, delivering the right amount of power for each load while metering the precise amount of fuel. When extra breakout force is needed, the operator can activate the automatic power boost to provide a 10-second power boost of up to 10 percent additional force. The machine’s straight-travel function automatically holds the machine in a true line while moving forward. Visit www.betterroads.com/info.
