CORE RoadEdge - Gravel Road Edge Stabiliser

CORE RoadEdge is most frequently specified for narrow roads, motorways and roads that experience high volumes of traffic on a daily basis. It’s designed as a gravel stabiliser that sits on the shoulder of the road, and due to its material being HDPE (High density polyethylene) and depth of cell, it can withstand all vehicle types making it a highly versatile product.

CORE RoadEdge is an economical way of achieveing the task of making roads wider, furthermore it is a product that improves the safety of roads and motorways as it offers a stable edge strip in which cars can use to move out of the way of traffic and offer them stability if they veer slightly off centre within the lane they are driving.

CORE RoadEdge can be installed to create stability and a solution to narrow or dangerous roads to provide more space for cars to operate and manouvere.

WHY IS CORE ROADEDGE USEFUL?

High Load Bearing

CORE RoadEdge’s grid design and construction provide cells of gravel which allow for extreme levels of pressure from vehicular traffic without the migration of the aggregte, thus making CORE RoadEdge a highly practical and versatile option to use on the sides of motorways and narrow roads that will experience a variety of traffic loads. The load bearing of CORE RoadEdge is a robust 260 tonne/sqm, enabling it to withstand all vehicular traffic that it may have to acommodate.

Prevention Over Repair

On roads that experience high volumes of traffic, cars driving over the edge of the road onto the verge and can cause costly damage. CORE RoadEdge is an economical and viable solution to preventing such damage – and the low weight of only 2.3kg per piece offers quick and easy installation.  Deeply extended embankments caused by trucks, lorries and agriculture machinery pose a high accident risk. If smaller cars get off the lane, they run the risk of slipping onto the embankment and losing control. The plastic honeycomb structure generates a rise-over noise and warns the driver in good time to get off that part of road.

Interlocking Mechanism

The individual pieces have connections at both short ends and are connected via the T pieces that connect together when one piece is laid underneath the one before it. The pieces are always laid into the loose installation bed and laying in the direction of the traffic is recommended due to other stages of the installation take place in the same direction. The T pieces of the panel on the short side are inserted into their counterparts on a previously installed panel at an angle of approximately 45 – 60° and then dropped into place.

The T-pieces always point opposite to the driving direction. The connection system automatically stabilises the panels in all directions during installation. Stepping onto the newly laid panel will fix the integrated ground spikes in the installation bed. The position of the panel in relation to the upper edge of the asphalt can be inspected afterwards and the installation bed adjusted where necessary.

WHAT VEHICLES CAN USE CORE DRIVE

Core Drive can be used by almost any wheeled vehicle, we have grids suitable for vehicles ranging from golf buggies to fire engines. Please do not hesitate to contact us directly to discuss the best grid for your project.

Please note, whilst some of our grids are capable of taking HGV traffic loads, no plastic gravel stabilising grid available on today’s market will withstand the immense pressure and friction created by the screwing action of a large vehicle performing a stationary maneuver.

IS CORE DRIVE ENVIRONMENTALLY FRIENDLY

Yes!

Core Drive provides a porous paving solutions which returns water back to the environment where it belongs instead of pooling or causing the flooding problems of traditional driveway surfaces. In addition Core Drive is made from pure white recyclable virgin Polypropylene (PP) or 100% recycled black PP both of which are UV and heat resistant.

ARE CORE DRIVE INSTALLATIONS EAST TO MAINTAIN

Yes!

While you do not have the rutting and aggregate migration of traditional gravel installations, you still need to occasionally rake the gravel.

If you can see the Core Drive structure, you should rake the gravel to completely cover the honeycomb, thus preventing damage.

CAN CORE DRIVE BE USED ON DRIVEWAYS THAT ARE ON A SLOPE

Yes!

Core Drive grids can be used on driveways that have up to a 20% gradient, which is equivalent to an 11-degree angle or a 1 in 5 fall.

If you are planning to use Core Drive on an area that has a steep gradient (15-20%) and it is likely that your vehicle will come to a complete stop whilst still on the gradient it would be prudent to install ‘traction strips’ to allow your vehicle to accelerate on the slope without wheel-spinning and damaging the Core Drive grid.

IS THERE A SUGGESTED SPEED LIMIT FOR CORE DRIVE GRIDS

In theory there is no suggested speed limit. However if you were to break sharply the friction caused by the skidding vehicle would be similar to that of a wheel-spinning vehicle. This could potentially damage the Core Drive grid.  For this reason we would advise a maximum speed limit of 5mph.

IS CORE DRIVE EASY TO INSTALL

Yes!

We have a unique interlocking system and all of our grids come with a non-woven geotextile weed membrane heat-welded to the underside. Please take a quick look at our install video to see how easy it really is.

WHAT TYPE OF GRAVEL SHOULD I USE

For best results we recommend using an angular aggregate as this helps the surface dressing to stay in place.

Your finished Core Drive will consist of hundreds if not thousands of small cells full of loose aggregate. This unique design prevents the aggregate from shifting or over compacting, allowing the surface dressing of aggregate used to cover the cells and bite into the loose aggregate contained in the cellular structure, greatly reducing the amount of movement in the finished surface.

IS CORE DRIVE SUDS COMPLIANT

YesSUDS

Our products are one of the best Sustainable Urban Drainage Solutions available.

A SUDS compliant subbase build up should contain nothing smaller than 2mm in its construction, this is referred to as a  ‘no fines’ or ‘reduced fines’ build up. By using a reduced fines subbase material such as type 3 or 4-40mm clean aggregate, below a grit bedding layer, the water is able to infiltrate through the complete build up and back into the subsoil.

Whilst all of our grids are completely porous and can therefore form a SUDS  surface course, the free moving loose aggregate  layers required to form a truly SUDS compliant surface can prove difficult to compact adequately to provide a sufficiently stable subbase.

Our CORE Commercial grid is ideal for projects where a truly SUDS compliant surface build up is required. The perforated HDPE base provides maximum stability whilst allowing the water to flow freely through the surface course.

The moulded ground spikes improve the structural integrity by anchoring the grids into the aggregate bedding layer, the perforated HDPE base forms a structural layer between the aggregate bed and the aggregate within the grid forming the wearing course.

IS CORE DRIVE SUITABLE FOR WHEELCHAIR USERS (DDA COMPLIANT)

With regard to local government approval of our system there is no such document or set standard in the UK with reference to disabled access, which is why we refer to the American version in our literature where we have obtained U.S. approval.

In the UK Governments approved document, part M “access to and use of buildings” it states that the surface of an approach available to a wheelchair user should be firm enough to support the weight of the user and his or her wheelchair and smooth enough to permit easy maneuver. It should also take account of the needs of stick and crutch users.

Loose laid materials such as gravel and shingle are considered unsuitable for the approach. However we have proven through video footage and case study that loose aggregate laid in a CORE Drive or CORE Path stabiliser is sufficiently stable to allow safe passage for all of the above named users.

 

WILL WEEDS GROW THROUGH THE GRAVEL

No.

The geotextile membrane material that is heat welded to the bottom of Core Drive prevents weed growth from underneath the grid. You may however experience a few air born weeds that are caused by birds dropping seeds or natural pollination; these can be easily removed due to the fact they are restricted to rooting in a single cell full of loose gravel.
