WESSEX ACCELERATED POLISHING MACHINE 
 

Wessex first manufactured an Accelerated Polishing Machine over 30 years ago, and were involved both in the development in the machine and the test procedures based on it.  
 
More than 1000 of these machines have been supplied globally to Materials Laboratories, Consulting Engineers and Research Institutions. 

APPLICATION 

In 1950 increased traffic flows and higher speeds, together with concerns about road safety led to research into the relationship between road materials and skid-resistance. Research at the UK Road Research Laboratory showed a significant relationship between polishing of aggregates used in road surfaces and skid resistance. 
 
Tests were devised using an Accelerated Polishing Machine and a friction measuring device, a Skid-Tester (otherwise known as the Pendulum, also manufactured and supplied by Wessex), to determine a Polished Stone Value. 
 
These developments have resulted in a simple and inexpensive procedure to determine skid resistance in advance of a road being built. Use of the PSV tests in road construction has had a major influence in the reduction of accidents.
