 Compliance testing of reinstatements

Utilities' reinstatements of the highway Studies in Europe and North America into the effect of utility works on the performance of highways have shown that trenching can have a detrimental effect on both the surface condition and the underlying structure of a highway, thereby shortening its service life. Previous research by the CSS in this area found four kinds of damage that may result from trenching activity: .the possibility of the excavation process weakening the adjacent pavement, which then further deteriorates after a reinstatement is completed; .the creation of a weak boundary between a reinstatement and the adjacent pavement; .a deteriorating pavement that may cause an adjacent trench to fail earlier than expected; .surface deterioration and visual disbenefit arising from the works. The Traffic Management Act 2004 has provisions to enable highway authorities to recover funding (contribution to costs of making good long-term damage) from those responsible for the long premature deterioration. This report describes the methods used to determine the additional maintenance costs borne by authorities as a result of premature highway deterioration, and goes on to develop a schedule of charge rates that could be levied against those opening the highway, in order to recover these costs. The research was undertaken by TRL with funding from the CSS. ------------KM7Ef1GI3cH2Ef1ae0KM7KM7Ef1Ij5 Content-Disposition: form-data; name="folder" /ukrlg_admin/
