A hot bitumen emulsion is sprayed onto the road surface followed immediately with an application of high quality, washed and graded aggregate. These are then rolled to ensure proper embedment of the aggregate into the binder. This provides an economical and water impervious seal with the added benefit of a much-improved surface texture.
How is it applied?
Surface Dressing applications are made using bitumen emulsion sprayers and aggregate spreaders. It can be used to treat both lightly and heavily trafficked roads and the proper choice and rate of application of materials is essential to ensure adequate performance. Applications can be made in one or two layers and also in combination with other surface sealing techniques such as Road Seal to achieve the desired result. Aggregates resistant to polishing and polymer modified bitumen are preferred on high traffic roads or on stressed areas to improve skid resistance and chipping retention. Our road surface dressing equipment combines the spraying of hot bitumen and application of aggregate in one machine. This offers the best conditions for maximising performance of the binder aggregate combination. Our equipment applies the aggregate immediately to the hot sprayed bitumen. This gives an inter contact time of less than one second. Cost benefits The cost is substantially lower than for traditional asphalt surfacing. Dramatically rising costs of traditional asphalt surfacing methods make surface dressing a cost effective and high quality alternative. We will be pleased to provide a no-obligation quote..
