This is a cost effective method to waterproof, provide a desired skid resistance and improve light surface deterioration on any class of road. The Surface Dressing season is between May – August.
All our surface dressings, both standard and premium, are carried out in accordance with the requirements of National Highways Sector Scheme 13, and clause 919 (Recipe Specification) & clause 922 (Design, Application and End Product Performance) of the Specification for Highway Works [& Series 900; clause 7.2 of the NRA Specification for Road Works]. Our compliance with the Scheme is independently assessed by the BSI (British Standards Institute).

PREMIUM SURFACE DRESSING
Northstone use both theTotal Bitumen proven EMULSIS® range, and the ICB Emulsion range. Regards non-modified K1-70 binder for standard dressings and polymer modified grade binders for Premium dressings.
The polymer modification binders are used in areas of high traffic stress i.e. high traffic volume/ junctions/ gradients, as well as in multiple layer dressings. Giving clear benefits in terms of durability; adhesion, flexibility and resistance to extremes of temperature. Less prone to `bleeding/fatting up’ in hot weather, nor `Fretting’ due to brittle failure in low temperatures.
- ICB (Cold Chon) Polymer 80; is a C70BPF1 designated emulsion, as defined by EN 13808:2005. A user-friendly Premium Grade binder, with an application temperature of 80 – 85°C.
- Emulsis Ultra; is a C69BP4 designated emulsion, as defined by EN 13808:2005. An intermediate quality binder designed to bridge the gap between conventional & higher performance binders. Able to develop strength and cope with stresses in the early life, even in unfavourable ambient conditions. (HAPAS Certificate 14/H215)
- Emulsis Satis; is a C71BP4 designated emulsion, class 5, as defined by EN 13808:2005. A Premium Grade binder, with intrinsic innovative technology to enable application at lower temperatures, yet maintain an even distribution of binder across the spraybar. Application temperature of 70 – 75°C. (HAPAS Certificate 14/H215)
- Emulsis Supreme; is a C70BP4 designated emulsion, class 6, as defined by EN 13808:2005. A tough, durable and elastic Super Premium Grade binder, also with 70 – 75°C lower temperature application.
Northstone offers a complete package for both conventional and premium dressings, covering design, aggregate supply, installation and aftercare. Single coat, racked-in, double or sandwich dressings are designed to meet performance criteria for individual Sites as appropriate.
