Extends the service life of spray seal pavements The HUESKER chipseal grid consists of a highly resistant composite engineered for spray seal applications. The combination of a paving geotextile with an added reinforcing grid provides both a waterproofing and reinforcement function, resulting in a more durable and cost-effective rehabilitation than conventional methods. The geotextile component comprises a nonwoven with optimum bitumen retention capacity. When impregnated with bitumen it acts as a barrier to the ingress of water, protecting the pavement structure. The integrated biaxial reinforcing grid made of high tenacity polyester yarns strengthens and supports the sealed surface by improving the rupture behaviour of the geotextile. Additionally, it contributes to a significant delay in crack propagation. The optimised design also assists with reduction of bitumen migration (bleeding) while enhancing aggregate retention on the surface. HUESKER chipseal grid‘s flexibility and strength permits its installation on existing as well as milled surfaces and provides a strong bond to the underlying surface.
