TESTS ON BITUMINOUS MIXTURES USED FOR SEALING JOINTS IN CONCRETE SURFACINGS

ENSAYOS DE MEZCLAS ASFASTICAS PARA EL ELLADO DE JUNTAS EN PAVIMENTOS DE HORMIGON

For the hot sealing of joints in concrete surfacings, Bituminous mixtures should fulfill the following requirements: (1) easy and even filling of cracks approximately 10mm wide, at temperatures compatible with real working conditions; (2) complete sealing preventing water seepage; (3) deformability allowing the surfacing A certain amount of play without formation of cracks of unglueing of the concrete; (4) impact strength at low temperatures (0 degrees c); (5) weak reaction to temperature changes; (6) no tendency towards sedimentation, if inert materials are used. Various tests for assessing the properties mentioned above are examined. Results are given of tests on siliceous sand/asfasol h mixtures, limestone filler/asfasol h mixtures, industrial talc/asfasol H mixtures, asbestos/asfasol h mixtures, vulcanized rubber/ asfasolh mixtures, and rubber/oil/asfasol h mixtures. The number of the covering abstract of the annual meeting is 100980. /TRRL/
