Trials for Klaruw's K190 road surface retexturing

Northern Ireland's Department for Regional Development (DRD) Roads Service has completed trials of the Klaruwtex190 bush hammering process on sections of the A5 south of Londonderry.

Roads Service engineers are evaluating the all-weather, environmentally friendly process as an option for restoring wet weather skid resistance to complement surface dressing treatments currently used.

Klaruw RMS, the subsidiary that carries out direct contracting of the Klaruwtex190 (K190) process, has treated a total of 17,500m2 of road surface comprising HRA (hot rolled asphalt) at two trial sites.

The K190 process provides controllable retexturing of any sound, natural aggregate surface course to restore micro-texture, and hence the surface friction that contributes to skid resistance.

Able to operate in wet weather and with minimal traffic management, the treatment does not use any materials or hot processes and generates a minimum of arisings.

This results in a low carbon footprint and negligible waste disposal costs.

The Roads Service will be evaluating friction measurements for the K190 treated sites following its annual road condition surveys.

Klaruw has completed the first UK trials of its latest retexturing innovation, the Macrotex (MAT) wet application shot-blasting plant which restores macro-texture to reduce surface water aqua-planing.

A prototype of the machine has been put through its paces by HA Area 10 Managing Agent Contractor, A-one+, and North Wales Trunk Road Agency (NWRTA), on sections of the M56 and A55 in North Wales.
