Repairing Potholes for the Long-TermEngineering360 News Desk | February 12, 2017
Researchers at Brunel University London are putting the heat on potholes. They have applied infrared heating technology in a way that could save local UK authorities £3.5bn in 2019 by making repairs cheaper and longer-lasting.
While road maintenance teams already use commercially operated heaters to repair potholes, most just deliver hot material for filling and compaction.
The researchers maintain that “this leads to a higher risk of pothole failure due to inadequate heating at the interface between the pavement and fill material. A lack of temperature control deep within the mass also causes failures.”
Backed by engineering firm, Epicuro, the researchers developed the Controlled Pothole Repair System, a portable machine that uses infrared heating to heat pothole surface and deep underneath before repair. A 3D thermal model is used to model and control the repair process.
