Velocity road patching machines deployed to fill potholes
Two Velocity road patching machines are being deployed across West Sussex to proactively seek and fill potholes before the regular inspections by Highways teams. The initiative is part of a two-pronged “attack” on potholes, with the innovative Velocity system used in addition to the traditional inspection/repair regime.
The Velocity road patching machines are used to fill potholes sizeable enough to need filling under safety criteria but also to repair defects likely to further deteriorate and reach that level in the near future. When selecting routes to attend, the teams operating the Velocity road patching machines focus on those with the highest, historic pothole numbers, to try to optimise value for money and results.
In the first four weeks of the 2022/23 financial year, the two Velocity road patching machines completed just over 1,100 repairs and treated approximately 3,000sqm of the highway network.
Importance of smoother road conditions
Joy Dennis, West Sussex County Council’s Cabinet Member for Highways and Transport, said: “We know how important the condition of our roads is to residents and are proactively tackling the issue of potholes. The deployment of two Velocity machines follows last year’s successful trial, when we were impressed with the speed and quality of the patching system and the audited results post-repair.
“Fixing potholes is really important, but we also have our ongoing £32million programme of investment in highways and transport, which includes an unprecedented level of investment in road and footway repairs in recent years. Within the programme are a significant number of road resurfacing schemes.
“Resurfacing a road produces a smoother surface, reducing road noise and increasing resilience to potholes – a longer-term solution to pothole issues compared to small-scale repairs.”
Also agreed in the council’s capital budget in March was a further £21million funding, over the next five years, for priority areas such as carriageway improvements and repairs.
Fact file on how Velocity road patching machines work
- High-velocity air is used to remove all dust and debris and open-up cracks at the bottom of the pothole to ensure a solid, stable repair
- A cold bitumen emulsion is forced into every crack and crevice under pressure, sealing it and making it water-tight
- The operator switches on the aggregate mix, which is fired at high velocity through a nozzle, evenly coating the granules with bitumen emulsion and building up the waterproof seal, with no joints
- If required, the aggregate mix is compacted with a “wacker plate” and the repair is traffic ready – far faster than by traditional methods, reducing the time needed for traffic management
Potholes and how people can help
- Unfortunately, roads are not permanent structures and deteriorate over time from constant use, the weight of vehicles using them and the effects of weather. With the expansion and contraction caused by temperature change, deterioration will occur, resulting in new potholes
- The County Council is responsible for maintaining around 2,500 miles of road: A and B roads are ordinarily inspected monthly, C-class and main distributor roads on a three or six-monthly basis and declassified roads are typically inspected annually
- Highways officers cannot be everywhere, so the public’s eyes and help in spotting and reporting concerns are helpful via the County Council’s online pothole reporting form
