Abstract

[Abstract]: This Dissertation addresses the design, development and construction of an automated soil compactor for the preparation of California Bearing Ratio (CBR) and Proctor samples. The necessity for this machine is primarily due to an ever increasing number of workers compensation claims within the soil testing and certification industry. The technicians that are currently preparing substrate samples by means of a manual compaction hammer are subjected to extended periods of use of this apparatus, causing Repetitive Strain Injury and Occupational Overuse Syndrome in the shoulders, neck and elbows. Therefore, a mechanization of the manual compaction methods was required. In addition to addressing the physical strain issues, the machine was also designed to fully comply with current Australian Standards. Multiple automatic machines are available on the market; however none achieve full compliance to the methods set out in AS1289. The design was therefore developed into a machine that mimics the manual compaction method exactly while eliminating the inherent human error of the manual method. The prototype Compaction Machine has successfully passed product testing as a viable, accurate and efficient tool for use within the Civil Testing Industry while fully complying with the relevant Australian Standards. The machine’s capabilities allow the unit to be used in researching more efficient compaction techniques; a very useful, promising future is ahead.
