Abstract
Recently, the domestic constructions have continuously promoted in Taiwan, especially in transportation constructions. During each engineering construction process, selecting an efficient and suitable testing method to maintain construction quality is essential and also provides positive assistance to the construction progress. Therefore, finding a way to speed up the test process and to achieve the project within the time schedule has become an important research topic as well as the aim of this study.
For instance, after the base grade has been backfilled and the plat load test has immediately carried out, the testing success rate is low. Herein, the DCP test is employed prior to the plate loading test. The statistic results revealed that the success rate has been drastically improved. Hence, with the DCP test prior to plate load test, the testing process of embankment filling of road construction will speed up and lead to time efficient and cost benefit.
This study aimed at the analysis of the time spend and cost saving for DCP test and Plate loading test. The study results reveal that the DCP test is cheaper and less testing time than the plate load test. Also, combining the DCP and plate load test may increase the testing success rate from 20% to 90%. Finally, it suggests accepting the engineering construction standard to include the DCP test as one of the embankment filling test methods.
