Overbanding & Fill and Overband

Overband Overview and the Case For Sealing Cracks

  

As vehicle speeds increase, the water pressure in cracks rapidly exceeds the 10MPa strength of asphalt leading to rapid break-up of the road surface.  

At cracks up to 20mm deep, the highway will break up when vehicle speeds exceed 35 mph. Sealing cracks against water ingress protects the road from rapid break up and eventual pothole formation. Fill and Overband material is 100% flexible.
