Paving Fabric in a Chip Seal Programme

The case for putting paving fabric under a chip seal, using Mirafi MPV500CS, including the claim that it doubles the life of the seal and removes the need for future crack filling.

What it covers

  • Pavement preservation, and moving from worst-first to right-treatment-right-time
  • How fabric under a chip seal bridges cracks in the surface below
  • Doubling chip seal life
  • Reducing the effects of thermal expansion and contraction
  • Removing the need for future crack filling
  • A continuous moisture barrier over the pavement

Notes from us

This is a budget argument dressed as a product brochure, and it is aimed at whoever plans your preservation programme rather than whoever runs the crew.

The claim that matters: fabric under the seal is still bridging the cracks underneath after fifteen years, so the sections do not come back onto the crack-sealing list. If you are resealing the same roads on a short cycle, the cost comparison is not fabric against no fabric, it is one long cycle against two short ones plus the crack sealing in between.

The framing about moving from worst-first to right-treatment-right-time is the part to take to a council meeting. Fabric-reinforced chip seal is an optimum-timing treatment: it works on a pavement that is cracked but sound, and it is wasted on one that is already failing structurally.

Road Fabrics installs chip seal with fabric. It is a sequencing job, with the fabric going into hot binder and the chip spreader right behind. Tell us about the programme, and the installation guide has the field procedure.
