RT55 Micro Trench Summary
RT55 easily averaged 6 + feet per minute in solid 5-6 inches of asphalt. All cutting was 100% “dry” cut. Trench was 99% clean to 12” depth. FX60-800 gallon cyclonic vacuum would increase productivity. 1.25 inch conical bit blade used. Standard slurry backfill of 2-sack slurry. Almost no labor necessary to clean surface roadway post cut. No dust control necessary, vacuum eliminates all airborne particles. All photos are when machine is operating. Attachment is “quick change” wheel, taking less than 3 minutes to change. Next generation attachment available April 1st, will have:
● Adjustable depth in one inch increments.● Fully hydraulic traversing.
Airless tires will be added to production RT55 for micro-trenching.
