건설방식에 따른 고무차륜 AGT 주행로의 현장압축강도 평가

The rubber tired AGT runway have been built in the cast-in-place method. It has occurred several problems resulted from maintenance and durability because of limitation of the quality control. It is being developed in pre-casted runway in order to improve these problems and others. In this paper, the field compressive strength tests are performed to compare material properties for each construction method. Elastic waves and Schmidt hammer test was used as field test methods considering the site characteristics. As a result, it was found that the section of cast-in-place does not reach the criteria in accordance with the quality level. However, the section of pre-casted is secured in sufficient quality level.
