MANCHESTER EVENING NEWS: Why are there so many potholes on Manchester's roads?

    Press/Media: Expert comment

    Description

    according to Dr Domenico Lombardi, deputy director of research at Manchester University’s School of Mechanical, Aerospace and Civil Engineering.

    He said: “When it rains, water leaks through the pavement into the ground and washes out the finer material found below.

    “If this action is protracted over time - like during periods of sustained rainfall - the ground surface starts to sink, forming sharp edged depression in the carriageways.”

    They seem to be getting worse, according to Dr Lombardi, because they are.

    He added: “The last decade has marked a period of increase in the number of potholes.

    “Arguably, this can be attributed to an increasing number of extreme rainfall events–according to the Met Office, 2012 was the second wettest year in the UK since national records began in 1910, and an aging transport infrastructure.

    “Therefore, timely repairs, and more sustainable drainage systems, including more green urban areas, can greatly minimise the occurrence of potholes.”

      Correct, according to Dr Domenico Lombardi, deputy director of research at Manchester University’s School of Mechanical, Aerospace and Civil Engineering.

      He said: “When it rains, water leaks through the pavement into the ground and washes out the finer material found below.

      So why do the potholes seem to be getting worse?

      They seem to be getting worse, according to Dr Lombardi, because they are.
