Abstract
An otherwise compliant and typical Australian airport crushed rock base course material was separated into fractions and recombined to produce samples of non-fines contents. Samples were compacted at optimum moisture content and then allowed to dry back to 60% of optimum, prior to repeated load triaxial testing in both drained and undrained condition. The repeated load triaxial modulus and cumulative deformation were compared for samples prepared with fines contents ranging from 6-14%. Over this range, increasing fines content had no detrimental effect on either the modulus or deformation of the crushed rock material. Although the results are limited in terms of materials and test conditions, it was concluded that the repeated load triaxial test has potential for a more performance-based specification of airport crushed rock sources. Further research is recommended to extend these findings to other materials and to harsher test conditions.
