The use of brick as a paving material has a long history. Over the past few years brick has again been specified in vehicular areas. Engineers are now requesting information on the skid resistance properties of brick. A research project was undertaken to determine brick's skid resistance, as well as to compare brick's frictional characteristics with those of other paving materials. It was also desired to determine if skid resistance correlated with other physical properties of brick.
Tests using the British Pendulum Tester confirmed that these brick have excellent frictional characteristics. It was also determined that skid resistance does not correlate with brick's compressive strength, abrasion index nor cold water absorption.
