âIn-Situâ Road Recycling Technique Used In Bath & North Eastsomerset
VolkerHighways and Bath & North East Somerset Council have completed remedial work to Charlton Road, Keynsham, using innovative âin-situâ recycling. This is a method of reconstruction which takes place entirely on-site, eliminating wastage and reducing carbon emissions.Working with specialist contractor, SPL, the team used their latest recycling plant to first pulverise the existing carriageway then mix a blended cement binder while adding water to create a hydraulically bound foundation layer. The layer uses 97% of the recycled existing road material, with just 3% new materials, which is then compacted and re-profiled to reduce the likelihood of the road failing, in the future.To ensure the location was suitable for this method of work, site testing was undertaken to make sure the existing road material was appropriate and compliant. Tar testing was also carried out during this exercise. Charlton Road is a busy road, just South of Keynsham, and due to the complexity of the work, local diversions were ongoing for several weeks. In addition, Parkhouse Lane, just off Charlton Road, is a dead-end residential road. To minimise disruption to residents, work began at the Northern End of the scheme to complete the recycling of the first 150m of road. The completed recycled layer receives a spray of bituminous emulsion which prevents drying out and so the hydration of the recycled layer can take place slowly. The emulsion is protected using a covering of bituminous grit. This temporary surface allows the carriageway to be trafficked and so after the first day, access for Parkhouse Lane residents was enabled. Thanks to improved efficiency, the scheme was completed ahead of programme, allowing surfacing to take place sooner, and the road to be opened ahead of time. Carbon savings of 193 tonnes were derived during the scheme, thatâs the equivalent of driving around the world 34 times! In addition, the process saved 316 lorry movements thanks to the in-situ recycling method. The speed of the process enabled the road to receive a long-term fix, in a short period of time, which should last around 15 years. Minimal intervention should be required going forward and in the unlikely event the recycling requires deeper treatment in the future, the material can be recycled again.

City Of Tampa And Causeway One.Network Launch Work Zone Safety Initiative
British road management and roadwork information provider Causeway one.network has announced that the city of Tampa, Florida has deployed Live Link, the companyâs premiere work zone safety software, to reduce congestion and protect workers and the driving public. Live Link allows workers to update lane closure information through the major GPS providers, notifying the public directly from the job site. That information is traditionally generated from paper work permits and spreadsheets that are out of date almost as soon as they are written. The software will provide Tampaâs traffic managers with a single operational view of work zones, and related incidents and events on the cityâs public roads, increasing efficiency, reducing travel times and improving safety. Because other regional agencies are using the Causeway one.network platfrom, city traffic mangers will also be able expand their view into neighboring jurisdictions to anticipate out of town situations that could impact drivers in Tampa. Barry Matlack, one.networkâs VP of North America says the initiative will bring a new level of accuracy to often flawed work zone information. âWith nearly 400,000 residents and more than 26-million visitors per year, this project has major lifestyle implications for the entire community,â he said. âThis project digitizes that entire process from beginning to end and arms traffic managers with real-time decision enhancing tools. Itâs the difference between the free flow of traffic and congestion, and weâre excited to provide those traffic managers with the tools to be effective in their jobs.â Florida is the first state to deploy the Live Link solution. The software was developed and vetted in the United Kingdom before being deployed by the Florida Department of Transportation (FDOT) on all state roads in 2022. Since then, other âSunshine Stateâ agencies including the Central Florida Expressway Authority, the Tampa Hillsborough Expressway Authority and Hillsborough County have added the Causeway one.network platform to their work zone safety tools. Using the intuitive Live Link mobile app solution, workers at a job site can update their location, specific lane closures and even whether a work zone is active. That information is transmitted directly to the major GPS mapping providers including Google, Waze and Apple Maps providing information to drivers in the format, location and time they need it. Matlack believes Live Link will make a significant difference for work crews, residents and visitors in Tampa. âWe are committed to making roadways safer and as efficient as possible,â he said. âTampa is a progressive traffic management city, and working with people who share our goals and commitment is extremely rewarding.â

A9 Road Safety To Benefit From New Road Marking And Solar Road Studs
A stretch of the A9 on the west of the Cairngorms in Scotland is due to be closed overnight for six weeks for essential road marking and the installation of new solar road studs. BEAR Scotland, on behalf of Transport Scotland will be working on a 7.5 mile (12km) single-lane section between the Kincraig duals and the A938 Carrbridge junction from Monday 26 August for six weeks. Theyâll be working with road marking company WJ Group, who in turn will be installing Clearview Intelligence SolarLite road studs. Works will be carried out from 7pm to 6am to minimise disruption, with no works on Saturday and Sunday nights. Two-way traffic lights with a convoy system will be in use to protect the workforce and road users. SolarLite studs provide ten times better visibility than traditional reflective studs, illuminating of up to 900 metres. This significantly increases driver reaction times, delivers ten nightsâ operation on three hours of bright daylight and gives drivers a clear indication of lanes and junctions in all weather, enhancing driver confidence. Chris Keenan, Director of Business â Scotland at Clearview Intelligence commented: âWe are pleased to see the ongoing investment and enhancements to the A9, highlighted by the implementation of our solar powered road studs and WJâs high-quality markings. This progress underscores the effectiveness of these innovations in enhancing safety across the Transport Scotland and Bear Scotland network.â Complementing the SolarLite road studs is WJ Groupâs Weatherline Plus high-performance road marking, which features a unique dotted profile that enhances visibility, particularly during wet nights, outperforming other products in similar conditions by rising above water, ensuring consistent retro-reflection. It includes a bio-based binder, offers a five-year lifespan, and reduces carbon emissions by 72% compared to traditional thermoplastics, which WJ says makes it an environmentally responsible choice Brian Smith, General Manager of WJ Scotland, highlighted the importance of this collaboration: âWorking with Clearview Intelligence allows us to deliver exceptional road safety solutions. The SolarLite road studs are a perfect example of how innovation can enhance safety while also supporting sustainability by reducing the need for street lighting. We are excited to see the positive impact these upgrades will have on the A9.â Ian Stewart, BEAR Scotlandâs Northwest Representative said: âThese road marking and road stud refresh works on the A9 will greatly improve visibility and safety for road users.â (Picture courtesy of WJ)

Road Safety Benefits Highlighted As Acusensus Distracted Driving And Seatbelt Cameras Go Live Across Devon And Cornwall
The UK manager of road safety technology company Acusensus says the first long-term use of its distracted driving enforcement solution in the UK is âgreat newsâ for drivers. Geoff Collins, who leads the Australian businessâs operations here has agreed a twelve-month operation using trailers across Devon and Cornwall, working with the police, Vision Zero South West and supported by AECOM. The âHeads Upâ equipment uses specially equipped cameras with technology to see through the windscreen and into the vehicle, identifying cases where people are using their phones or not wearing a seatbelt as they drive past. âWe have been running short-term proof-of-concept programmes across the country for two years now,â Mr Collins explained, âBut this is the first time we have a long-term operational scheme to monitor and enforce dangerous driving on our roads. Safe drivers who buckle up and leave their phones alone will welcome the installations, because theyâre there to spot the dangerous minority who think they can ignore the rules, creating a hazard for everyone.â The cameras are optimised to flag up likely violations, using advanced AI software that analyses images in near real time. When the software identifies a possible case of distracted driving or of vehicle occupants not wearing a seatbelt, anonymised images are sent to a UK based secure cloud for human review, which validates if a potential offence has occurred. A further secondary check then allows for the creation of an offence file, which can be used by the police for prosecution, and indeed has as part of the early trials. Mr Collins continued: âMuch of the work we have done so far has been using the âHeads Upâ units to gather data on the scale of the problem on our roads. This installation in Devon and Cornwall is great news for safe drivers because it will lead to prosecutions or re-education of offenders which will have a long-term effect on changing driver behaviour and reducing needless death and serious injury on our roadsâ. In a two-week test in Devon and Cornwall earlier this year, the cameras detected 408 seatbelt offences and 162 mobile phone-related infractions at a single location, demonstrating the scale of the problem to be addressed. Statistics from Australia show that the first state-wide scheme rolled out in New South Wales in 2019 led to the number of mobile phone detections dropping by a factor of 6 (1 in 82 drivers in 2019 to 1 in 478 drivers in 2021). Subsequent Acusensus programmes in other Australian states have similarly shown positive changes in behaviour. The Parliamentary Advisory Council for Transport Safety says that three in ten vehicle occupants killed in road collisions were found to not be wearing a seatbelt, while the DfTâs Think! campaign points out that a driver is four times more likely to crash if using a mobile phone whilst they are driving.
