LockChip Sealed Surface Dressing

LockChip is the innovative sealed surface dressing system from BituChem. Achieving the excellent results follows several stages. The first sees the laying of conventional surface dressing. This can be done in any design at a depth of 6mm or 10mm and is either single or double racked. Once the newly dressed road has received two sweeps, BituChem’s contracting team applies the LockChip bitumen coating to fully seal the highway. The innovative binder sits within the macro-texture of the chips in the new surface.

The Benefits of LockChip Sealed Surface Dressing

This application significantly improves the early life retention of the chips in all areas of the dressing. Providing waterproofing and increased durability to prevent defects, cracks, and potholes. LockChip binder also enhances the appearance of the new surface to a deep, uniform black which is comparative to a new asphalt surface. Another major benefit of this sealed surface dressing for repairs is that the coating cures in 20 minutes, enabling the carriageway to be reopened quickly. On busy road networks with high levels of traffic this helps to minimise disruption to the public.
