PRELIMINARY FRAMEWORK FOR A RATIONAL BITUMINOUS MIX DESIGN TO MITIGATE PAVEMENT FAILURES --14TH ARRB CONFERENCE, 28 AUGUST - 2 SEPTEMBER, 1988, CANBERRA, ACT, AUSTRALIA; PROC. PARTS 1 - 8

Bituminous mix design and field compaction continually emerge as the main factors in pavement life and performance. Therefore, an attempt has been made to modify and/or to combine the current empirical mix design methods and the mechanistic approach, or to develop a new analytic procedure with the mechanical properties of mixture as well as components within a reasonable design period to mitigate pavement failures. An analytic mix design computer program has been developed to determine an initial bitumen content. Then current Marshall or/and hveem method is used to find the optimum bitumen content (obc) for the short term design. Consideration has been given to characterize some laboratory specimens by testing first with the hveem stabilometer to obtain a measure of frictional resistance and then followed with the Marshall stability to obtain a measure of cohesion. For the long term evaluation of bituminous mixture, various mechanistic approaches are applied to determine the final obc depending on the specific mode of distress (a). For the covering record of the conference, see IRRD no 808936.
