Road Stabilisation

What is Stabilisation?
Road Stabilisation is the process of incorporating small percentages of cement into in-situ or imported materials thereby turning these un-suitable or marginal soils into useful construction materials which can be easily placed and compacted to form part of the temporary or permanent works. The basic process dates back thousands of years but with it’s cost savings and environmental advantages it’s acceptance and use in the UK and throughout the rest of the World has grown dramatically over recent years. The following describes the process involved in stabilising a particular surface.

CRUSHING

The crushing stage takes out potholes, track grooves and loosens existing materials in preparation for the addition of the stabilising products. Any area can be stabilised as the crushing drum has a crushing depth of 0-300 mm and is capable of crushing hardcore, granite and tarmac. This is the preparation required before either cement is added.

SPREADING

The existing unbound surface has cement powder applied to the surface which is then mixed into the crushed material several times with the crusher to ensure an even spread.

LEVELLING (grading)                                                                                

The area is then graded to help with drainage using one of are graders.

COMPACTING (vibrating)

With the use of vibrating plates or a vibrating roller we compact the area which will then form a hardwearing surface with increased longevity due to the stabilisation methods used. It will set to provide a hard-bound surface capable of taking heavy traffic.

WHY SHOULD I USE CEMENT?

Cement is mixed with the crushed road surface. It is applied using a hopper which spreads the cement on the crushed area. The cement is then mixed in to the area with the crusher. Cement is suitable for agricultural areas and areas that take large amounts of heavy traffic.

SoilBind comes in a liquid form, it is diluted and then sprayed directly onto the road surface. It is an environmentally safe, non-hazardous and non-corrosive product. SoilBind is more suitable for areas that specifically require an environmentally friendly product, dust control and more domestic areas.
