The service life of a UK road or highway can depend on the correct drainage being installed, as maintaining the stability and durability of the road means keeping them as dry as possible.
This also keeps the road safe for users, both pedestrian and vehicular. Reduces maintenance costs, as poor drainage can result in hydroplaning following the pooling of water, which may accumulate on the road surface during rain.
Wet road surfaces reduce friction, leading to longer stopping distances for braking and can freeze during the night, leading to frozen roads and ice, which makes roads slippery and unsafe for users.
To protect roads, the surface water needs to be collected and removed from the body of the highway and disposed of, this includes microplastics and oils that can damage the carriageway.
If the correct drainage is not designed or installed, flooding and erosion can affect the structure of the road, neighbouring land and the surrounding environment.
To prevent road scour or erosion, effective surface water drainage for motorways, highways, trunk roads, urban roads and footpaths is essential.
Motorway drainage
A high-capacity drainage solution is required to ensure that strategic road and motorway drainage is optimised and kept free from standing water, a proven combined kerb and drain is required.
With over 40 years’ experience, the Marshalls Beany range offers alternate road drainage loadings, for motorways and ERAs (Emergency Refuge Areas) with our design team providing projects proposals that save on costs, carbon and installation times.
Our Beany Block and Mini Beanycombined kerb and drainage systems are a popular choice with our team able to provide BIM (Building Information Modelling) designs, CAD and 3D modelling.
Main road drainage
For main roads, highways and high traffic areas, such as public areas, the Standards for Highways recommend a D400 loading classification.
Our design team would generally offer a Mono Beany kerb drain for straight road drainage.
For any public realm projects, they would recommend our Drexus channel drainage solution
Urban road drainage
For urban road drainage, our highway team would recommend a Beany combined kerb and drainage system that is available with half battered and splayed options.
Industrial estate drainage
When designing surface water drainage for industrial estates where drainage is required for loading bays and areas with heavier vehicles require the highest loading class. Our highway engineers would recommend our Birco channel drain or Max-E cast iron/traffic drain.
Airports drainage
We can all imagine the drainage loading needed for airport and sea ports, so its no surprise that the most heavy-duty drainage solutions are required, at Marshalls, these include our Birco channel drain, Max-E channel and Traffic Drain.
Bridges, Viaducts and Culverts drainage
Design Manual for Roads and Bridges, requires surface water to be drained away from bridges to reduce corrosion, ensure they are safe and have a long lifespan typical of ductile iron.
As the only manufacturer to offer a Type I solution, our Bridge Beany is available with a D400 and E600 loading with our drainage engineers able to offer the most cost-effective option for your scheme.
Our design and engineering experts include Structural, Civil, Highway and Drainage Engineers that are available to find the best solution for your project and we recognise the value in sharing their knowledge. If you would like to know more about drainage in highways and public realm settings, we are happy to hold CPD seminars and training sessions, if you would like to know more please email lch@marshalls.co.uk
