USES AND POSSIBILITIES OF THE GYRATORY SHEAR PRESS

UTILISATIONS ET POSSIBILITES DE LA PRESSE A CISAILLEMENT GIRATOIRE

The author describes the press and test procedure, and gives data on compactibility and shear force. The test is applied to a gravel-bitumen mixture, and the following conclusions are drawn: (1) the addition of widely graded rounded sand does not alter the final compaction but markedly improves laying and compactibility; (2) an average 2/6 discontinuity results in an increase in final compaction (2 to 3%) for the same compaction energy; (3) the proportion of bitumen has a preponderant influence in relation to that of fines. Mention is made of studies undertaken to develop bituminous mixtures for maintenance, and it is shown how compaction curves can be used to forecast sensitivity to tracking. /TRRL/
