A versatile and economic solution for road strengthening, Stabilised Wet Mix has mechanical characteristics equivalent to hot mixes and is suitable for reshaping and reinforcing flexible road surfaces. The material is manufactured by adding 5% bitumen emulsion to a tried and tested grading clause 810 wet mix macadam.

Stabilised wet mix has been laid on national, regional and county roads carrying large volumes of heavy goods vehicles. It is particularly useful over bog ramparts where reduced thicknesses with equivalent strengths are required.

Stabilised Wet Mix consists of a mortar in which the fines are fully coated, leaving a dry stone to stone contact. This contact ensures that the mix is Stabilised against water ingress, which helps to prevent rutting and makes it a superior material to conventional hot mix macadams

Ordinary unbound wet mix has excellent dry strength but very poor wet strength. Failure occurs when this type of material becomes saturated, usually as a result of the seal breaking or water penetrating from the sides.

Test Results

Assessment of stabilised wet mix carried out by the University of Ulster and the National Road Authority (N.R.A.) confirm the outstanding qualities of this material.

The University of Ulster carried out a series of wheel tracking tests to determine the rutting resistance of a variety of the road materials. The result (illustration in Graph 1) show that both initially and over time, Stabilised Wet Mix macadam shows substantially less evidence of rutting in comparison to conventional dense basecourse macadam.

The National Roads Authority carried out tests to determine a wet/dry strength ratio for Stabilised Wet Mix. A target Duriez strength of 30Kn and a wet/dry strength ratio of 0.55 was proposed for Stabilised Wet Mix.

The actual test result indicated a 30Kn Duriez strength and a wet/dry strength ratio of 0.6. These test results indicate the substantial strength of this material under both dry and wet conditions.
