아스팔트 콘크리트 변형강도 시험에서의 적정 하중재하속도 선정 연구 = Determination of Proper Loading Speed for Deformation Strength Test of Asphalt Concretes

다국어 초록 (Multilingual Abstract)

This study was carried out to select proper loading speed for deformation strength (SD) of asphalt mixtures. Kim test using loading
head of diameter(40mm) with radius(10mm) was conducted to measure SD in different loading speed (10mm/min, 30mm/min, 50mm/min,
70mm/min) and wheel tracking test was also conducted. The regression analyses between the SD values and WT results were carried out
by loading speeds. Higher SD was observed as increasing loading speed. This means that loading speed is a high influencing factor on
SD. The loading speed of 30mm/min was found as an optimum for better correlation with WT results than any other speeds from the
regression analysis between SD and wheel tracking test results. SD value measured at other loading speed than 30mm/min has to apply
the conversion coefficients.
