Pope DesignTHE ROAD TERMITE


The Road Termite is an excavation system that not only digs the foundation for superhighways but also properly compacts the excavated foundation floor – all in one pass. It is a modular system that can excavate either a two-lane road, a three-lane road, or even a three-lane road with an HOV lane, including an inside and outside breakdown lane with all three options (to US roadbuilding specifications). With the help of GPS location and self-propelled units, it can all be done with one operator in one operator cab.


The main excavation unit has a removable digging head that can dig to a depth of up to 45in. Four track frames mounted on four separate telescopic legs control the angle of the digging head to maintain proper depth and road pitch at all times. The rear track frames raise to begin exaction – this also helps shift the centre of gravity forwards for better breakout force without adding extra weight to the machine.


Augers in a tunnel underneath the main excavation machine carry the dirt from the front digging head to the rear conveyor belt that lifts and deposits dirt into a high-capacity independent autonomous rear unit. This is completely self-controlled with the aid of sensors and GPS (with emergency manual override) and has a rear conveyor belt that lifts and loads dump trucks on the fly. It also has a series of vibratory compactors mounted to the front of the unit, so while the independent unit moves forwards or while it’s not loading dump trucks, it is providing proper compaction for the roadbed foundation.


When a wider roadbed foundation is required, excavation units without cabs can be added to either side, or both sides, of the main vehicle. They can also be staggered and overlap each other for custom-width roadbed foundations. The cab is mounted on a horizontal telescopic boom, which enables the operator to swing the cab out and over the additional autonomous excavation units for a better view of the cutting edges of the digging heads.


After a single pass on a pre-cleared properly graded path, the excavated compacted road foundation dug to a depth of 32in is ready for 21in of natural aggregate and 11in of concrete to meet the specifications of a concrete American highway. All in a day’s work…
