The article discusses the problems of maintaining 43 km of trunk road and 16 km of M1 motorway in Barnet. All the very heavily trafficked trunk roads are of flexible surfacing, mainly on a reinforced concrete base, all the motorway is concrete. With traffic volumes of up to 85000 vehicles per day, severe deterioration was taking place. It is planned to resurface the complete trunk road network within the next five years, with the least inconvenience to road user and resident. After trials to establish performance, noise and manoeuvrability, a cold plane profilometer with a 2.82 M rotary cutter was used for most of the work. One contractor has used a burner/planer with a 3.7 M wide rotary cutter. Old asphalt has been used to form hard standings and car parking areas. Some of the concrete base has needed stabilizing which has been carried out using the Balvac system by lifting the slab allowing the void below to be filled. (TRRL)
