A field compaction control test was conducted on a compacted lift. The mass of the material removed
Question:
A field compaction control test was conducted on a compacted lift. The mass of the material removed from the hole was 1820 g and the volume of the hole was found to be 955 cm3. A small sample of the soil lost 17 g in the drying test and the mass remaining after drying was 94 g. The laboratory control test results are shown in Fig. P5.16.
(a) If end-product specification requires 100% relative compaction and w = (optimum - 3%) to optimum + 1%), determine the acceptability of the field compaction and state why this is so.
(b) If it is not acceptable, what should be done to improve the compaction so that it will meet the specification?
