The £7 million investment was completed two weeks ahead of schedule and has seen roads all over Hampshire being treated.
Surface dressing is designed to seal the road surface from water damage and maintain its skid resistance, keeping the road in good condition for as long as possible and preventing potholes and other defects from forming.
Hampshire County Council's Executive Member for Transport and Environment, Councillor Rob Humby, said:
The County Council's Operation Resilience team has been working tirelessly over the spring and summer months to complete our annual surface dressing programme to ensure Hampshire motorists can keep moving. With an average of 140 miles of roads and footpaths treated each year, the team are already putting their skills and expertise into planning next year's programme.
By undertaking this preventative maintenance work the life of the roads are extended, therefore allowing the County Council to use its limited funding efficiently and effectively to keep Hampshire residents and businesses moving on the road network.
Paul Anderson, Account Director for Amey in Hampshire - the County Council's highways contractor, said:
The summer months see us undertaking a large scale programme of surface dressing works, working with Hampshire County Council and specialist subcontractors to improve the local roads. Working with such a varied team requires a lot of careful and detailed planning from all those involved to deliver the programme on-time, let alone deliver the programme early, and despite some difficult weather conditions which could have affected our timescales. Our thanks goes to everyone involved, and we're already well into planning for next year's season.
Surface dressing involves the road being sprayed with bitumen which provides a new waterproof seal, and then a thin layer of stone chippings is applied to the surface to improve its skid resistance. It has to be applied to a dry surface, so the programme gets underway in earnest during the spring and summer months, and lasts until the autumn.
Surface dressing is a cost effective preventative maintenance treatment that extends the life of the roads and ensures they stay in good condition for longer. By undertaking this programme of work, it means the highways budget can be deployed across more of Hampshire's roads and footways with the more extensive treatments focusing on sites where there has been greater road deterioration and where full resurfacing is needed.
