Impact and Durabilty Testing with BBA at Rednall Airfield

Durakerb is made from a composite material which includes reprocessed polymers (otherwise destined for landfill sites). The extreme lightness of this product is achieved through a combination of this highly informed material selection and a meticulous design.

The cellular and ribbed construction has been utilised to further lighten the product whilst maintaining the extremely high strength, much the same as key structures have been designed in the aeronautical and automotive world. Loading strength in excess of of 25 tons is easily achieved. Durakerb is manufactured under international patent and at temperatures of up to 260 degrees centigrade thus ensuring the Durakerb can withstand the high temperatures experienced during the laying of bituminous materials.

The positional stability of Durakerb is ensured by way of a robust flange integrated into the bottom face of the kerbstone. In addition the natural ingress of concrete up into the cellular chambers of the Durakerb during installation results in an extremely stable lay condition. UV stability is achieved through the use of UV stable materials.

Product Testing

Slip Skid test on Durakerb with BBA

Tests for slip/skid (BS/EN 1340) and compressive strengths (BS/EN 6072) have been conducted as well as in-situ dynamic impact testing. Durakerb was installed at a test site where HGV's and fork lift trucks could be driven at speed at the Durakerb, simulating the greatest real impact conditions. The HGV tests were monitored by the BBA and despite repeated impacts the Durakerb remained completely intact. No cracks or chips were experienced. Additionally, finite mechanical element analysis undertaken separately achieved the bending strength requirements of BS/EN 1340. Other testing was performed appraising the Durakerb's freeze thaw, abrasion, fire and water absorption properties, all testing produced satisfactory results.

The Durakerb has already been tested in the field by leading contractors working in unison with local authorities and, despite extreme heavy duty applications, damage rates experienced to date have been very low.

The results of the tests carried out on the Durakerb have been made available for viewing.
