Recently the Australian standard for soaked CBR determination has changed. The aim of the change to the standard is to make the results more repeatable and less susceptible to moisture variations within the laboratory. Curing times of samples have also been specified both prior to performing the Maximum Dry Density, and the remoulding of the […]
Last week, Lucas was again invited to speak at McKinnon Secondary College’s career afternoon. He presented predominantly on civil engineering to about 300 year 10 students who will be deciding their VCE subjects with a view to entering their desired course at university.

(118K) ABSTRACT: Vertical moisture barriers are used to minimise the seasonal movement of pavements on expansive soil subgrades. This paper discusses the performance of two types of barriers – geomembrane and L/FA grout curtain– at two test sites in Victoria, Australia.
(312K) ABSTRACT: This paper will present the findings of various research programs and laboratory tests on the effects of slow-setting cementitious stabilisation binders on marginal pavement materials. It will present the VicRoads evaluation of the slow-setting binder developed by Blue Circle Southern Cement, Alkali-Activated Slag (commercially known as “Roadment”). The information presented includes research work performed […]
