The area of failed tests were dried and retested and met required minimum 90% <br />of Maximum Dry Density. Accurate moisture contents for each sample were measured in the laboratory. <br />The two new Moisture -Density curves (15-0115 and 15-0130) submitted with the first quarter 2015 report <br />were included with the report.
