Test method: Determine degree of saturation in accordance with Queensland Department of Main Roads test method Q111D. Perform test within a period of 6 hours prior to the placement of the next pavement layer or surfacing.
Moisture content limits: Limit the maximum degrees of saturation to 65% for Class 1 material, and 70% for Class 2 and Class 3 materials. Where the moisture content limits are exceeded during construction, dry back pavement prior to covering with the next layer of pavement or surfacing.
