Client's Challenge

The reflective cracking that had previously appeared in busy Stephenson Drive, a bus route close to Leicester city centre, was accompanied by potholes and widespread surface deterioration. The principle cause was the instability of the concrete paving slabs underneath the asphalt surface course, due to rainwater infiltration into the founding support. There was also evidence of asphalt fatigue and rutting, extensive patching over fractured slabs, potholes, numerous service trenches, movement due to tree roots and some potential subgrade driven failures.

Tensar Solution

To mitigate the effects of the reflective cracking in the new asphalt surface layers, Tensar proposed Glasstex composite asphalt interlayer as a stress absorbing membrane interlayer (SAMI) to help dissipate the stress from potential movement in the unstable concrete foundation and as such, potentially halve the road maintenance requirements.
