| Abstract |
Current removing process is labor intensive and time consuming, employing a conventional grinding type manual machine.From a social and economic point of views, these kinds of manual tasks bring about social inconvenience and economic lossincluding traffic jam and high labor costs. The objective of the study was to develop and evaluate a road stripe removalequipment using water jet technology. The following shows the results. First, It was analyzed that the obtainable productivityfrom the equipment developed in the study is 280% compared to the current equipment. In this study, it was also calculated theBenefit/Cost Ratio and the result showed that the ratio is 3.28, so it is expected that the equipment can produce great benefits forthe relevant companies. Second, an analysis was also conducted on the traffic congestion cost, and the equipment could saveabout 2,550 million per day compared to the conventional equipment. Therefore, it is analyzed that the economic viability ofthe equipment is sufficient. |
