Title:
Selectable Cutting and Fragmentation of Damaged Runway Surfaces
Report Date:
2020-06-03
Abstract:
A demonstration of the Electro-Hydraulic Fracture (EHF) method has been completed successfully. As proposed, Hyperion constructed and demonstrated a "Proof-of-Principle" (PoP) EHF laboratory system that effectively fragmented large concrete block sections approximately 3-ft x 3-ft x 1-ft, from a larger 6-ft x 12-ft x 1-ft thick concrete slab into pieces sufficiently small that they could be removed easily by such standard equipment as a front end loader. The use of user-controlled, variable power was demonstrated to affect the degree of concrete slab fragmentation. In addition, techniques to use the EHF system in a controlled manner to segment off 90-corner sections without the use of a water-jet cutter were also demonstrated. but only partly successful.
