What Does Resealing Mean?
The procedure of resealing involves the precise application of bituminous liquid, creating an even, uniform coating on the road surface.
This treated surface is overlaid with aggregates, which are compacted to ensure a robust bond between the binder and the aggregate. The choice of bitumen application can range from hot-sprayed bitumen to cold-sprayed bituminous emulsion.
This versatile process enables the integration of innovative elements such as rubber compounds to bridge and reinforce cracks in the pavement, as well as petroleum-based additives that delay the curing process. By applying multiple layers of bitumen and aggregate, we can extend the surface's life, refine its texture for increased smoothness, and mitigate the noise generated by road traffic.
When Do We Opt For Resealing?
To further enhance structural integrity and crack-spanning capabilities, a fabric can be seamlessly incorporated into the process. The overall longevity of this surface treatment is contingent upon various factors, including the thickness of the binder and the intensity of road traffic.
Arterial roads, bearing heavy traffic loads, may achieve a service life of five to fifteen years, while low-speed, low-traffic streets, such as cul-de-sacs, can experience an impressive lifespan of up to 25 years.
