EVALUATION OF THE PHYSICAL AND MECHANICAL PROPERTIES OF ASPHALTIC MIXTURES BY MEANS OF TRIAXIAL TESTS

EVALUATION DE LAS CARACTERISTICAS FISICO-MECANICAS DE MEZCLAS ASFALTICAS MEDIANTE ENSAYOS TRIAXIALES

An analysis is made of different methods of compacting asphaltic mixtures for sample production in a height-to- diameter 2:1 ratio, with a view to comparing results and analyzing density uniformity among the samples. Hveem type dyanmic compaction with kneading is adopted. The experimental device constructed for triaxial testing is described; it features a heat stabilized chamber to test samples up to 15 cm in diameter using lateral pressures up to 28 kg/sq. cm. The properties of high quality asphaltic mixtures are determined, for four combinations of coarse and fine aggregates, of the all-round or the all-crushed type (crushed coarse, crushed fine; crushed coarse, round fine; round coarse, round fine; round coarse, crushed fine).
