LECTURE NOTES ON CONSTRUCTION PROJECT

2011-10-15  1.1 The Need for Project Management The construction industry is the largest industry in the world. It is more of a service than a manufacturing industry. Growth in this industry in fact is an indicator of the economic conditions of a country. This is because the construction industry consumes a wide employment circle of labor.

2021-6-5  From my experience it depends a lot on how is the compaction done. If you are compacting road crush with a vibratory plate you will get about 10 to 15% compaction. (This is based on you having a stable compacted base first. If you are putting the road crush on top of top soil you will lose more to compaction.)
