INFILTRATION OF FUELS AND WATER THROUGH PAVER JOINTS

This paper reports some investigations to determine the amount of fluid which can be expected to infiltrate through a paver surface. It also proposes a field test, which can be used to assess the amount of leakage of an existing pavement. Some results of previous researches are first outlined. In the laboratory tests, four one metre square areas of rectangular pavers were prepared, two using 80mm-thick concrete blocks, and two using 65mm-thick clay pavers. One area of each type of paving was sealed by ACM Pavseal, a proprietary liquid pre-polymer. Infiltration rates from water, aviation fuel, petrol, and diesel were carefully measured. Skid resistance tests were also conducted using a portable pendulum friction tester. Recent in-situ tests confirmed the laboratory infiltration tests. Sealing of paver joints with pavers was found to reduce fuel penetration to negligible levels. Sealing of concrete pavers with a liquid pre-polymer reduced infiltrations of water and the tested fuels. The skid resistance and slip resistance of concrete pavers was found satisfactory after sealing; for clay pavers, their values were improved after sealing with the pre-polymer. The laboratory equipment was found suitable for field measurements.
