This outstanding contribution to road safety is the result of over 10 years' intensive development by the Transport Road Research Laboratory (TRRL) of the Department of Scientific and Industrial Research - a British Government organization concerned with studying problems that arise in designing, building, maintaining and using public highways.

The New Model ' S885' version of the instrument has been specially strengthened to meet the demands of countries like Germany, who prefer a more rugged design. Model ' S885¡± also includes an additional scale for use in the laboratory at no extra cost.

The instrument which is direct reading, gives a measure of the friction between a skidding tyre and wet road surface. It provides the Highway Engineer with a practical means of obtaining reliable scientific evidence on which to take the appropriate measures to reduce skidding.

To ensure consistency and maintenance of standard all instruments are submitted to the British Standards Institute for calibration and approval before supply to customers.

ROADSTONE POLISHING

Studies of accident sites have revealed that the polishing of roadstone is a major factor in skidding. An important application of the Skid Tester is in the laboratory determination of the resistance of roadstone to polishing.

Scale for roadstone polishing is built into the machine. 6 special small rubber sliders can be supplied for this test: S886/5

Base Plate for laboratory use of skid tester with specimen mounting block S885/9

RUBBER SLIDERS

As the nature of the rubber used for sliders has a critical bearing on the performance for the Tester, and as no rubber properties can be guaranteed for longer than two years, the date of issue is marked on each slider.

Spare mounted rubber sliders for use with Main Tester: S886/6

Spare mounted rubber sliders for Stone Polishing Tests S886/5

The resistance of wet road surfaces to skidding can be checked by means of a Portable Skid-resistance Tester (Portable Pendulum Tester). This apparatus is used to measure the frictional resistance between a rubber slider (mounted on the end of a pendulum arm) and the road surface. This method provide a measure of frictional property, microtexture of surfaces, either in the field or in the laboratory

 

The quantity measured with the portable tester has been termed "Skid-resistance" and this correlates with the performance of a vehicle with patterned tyres braking with locked wheels on a wet road at 50 km/h.
