SKID-RESISTANCE MEASUREMENTS MADE ON SEVERAL SEGMENTAL BLOCK PAVEMENTS

Since little work has been done to date to determine the skid resistance of segmental block pavements, seven sites were chosen to represent as wide a cross section of pavemetns as possible. Sites chosen for evaluation included the 20 year old pavements in Chatsworth Natal and some newer pavements in the Capt and the Transvall. The pendulum tester and the SCRIM apparatus were used. This report details the skid-resistance results obtained and compares them with rating scales developed for other South African pavements. The results have shown that the block pavements tested were satisfactory for use by high speed vehicles when angular aggregates were used in the manufacture. Changes to manufacturing procedures are recommended for the use of blocks for pavements with speeds in excess of 50 km/h. (Author/TRRL)
