As professional surface contractors, we know that the surface or sub-surface layers of the road become deteriorated with the passage of time, so these layers need to be replaced. The existing layer is removed so as to lay the new surface. Generally resurfacing is very costly but it may last for at least ten years.
Roads are surface dressed while treating the road surface in order to stop it from getting worse. Such treatments are generally cheaper as compared to the expensive rebuilding work hence more roads can be maintained with the same budget.
GTG groundworks defines surface dressing as a cost-effective way of restoring the road surface and sealing it in one process. The surface dressing also improves skidding resistance making the roads safer, it helps to make the road waterproof, and it protects the roads against frost and water damage.
The road is sprayed with bitumen binder which is followed by a layer of stone chippings. A roller is used to press these chippings into the road surface. More chippings are applied to the surface that is actually required in order to complete the dressing process. This ensures the uniform coating of the emulsion. Ninety percent of excess chippings are swept away by our expert team of road surface dressing contractors before the road is opened to traffic.
Bitumen surface dressing is applicable from the month of April to September because in this process there is a requirement of warm dry weather which allows the dressing to become more established.
As experienced road surfacing contractors, we use a mixture of stone silicate aggregate debris and polymer modified bitumen binders are used to make the surface dressing. Emulsified asphalt as well as aggregate is used while constructing a successful chip seal. In fact selection of right material is very important in this process. In order to install abrasion sealing layers, surface treatments of various kinds are brought into use which is possible through the use of various hot and cold processes.
GTG Groundworks makes use of high viscosity asphalt because the success of the chip seal improves if the aggregate is embedded in the asphalt layer.
Bitumen surface dressing treatments offered by GTG groundworks represent a low-cost option for the rehabilitation of low-volume roads, but such treatments are not ideal for each and every project. These surface treatments have become an attractive alternative throughout the world where thin maintenance along with rehabilitation budgets is stretched over large roadway networks.
