“…Based on the stress ratio S which is the ratio between the maximum load applied and the bending-tensile strength of beams, the test used three stress ratios which are 0.70, 0.75, and 0.80. 16,22 Further, the stress ratio R, which is the ratio between the minimum load and the maximum load applied has been set at 0.1. For ordinary concrete beams, three fatigue specimens have been used for each loading.…”

“…They have not explored the mechanical properties of the prestressed concrete materials and the design parameters of prestressed pavements. Based on the results of an indoor test using beam specimens to simulate pavement surface, they showed that it is relatively economical and effective to use the beam‐simulated pavement to conduct the structural test . Thus, in this study, the 150 mm × 150 mm × 550 mm beam specimens have been used to simulate airport assembling‐type prestressed concrete pavement slabs.…”

To prevent airport pavements from suffering fatigue failure before the end of designed life and to construct high‐grade airport concrete pavements quickly, this study has developed a method which applies the prestressed concrete to airport pavements. A three‐point bending loading scheme has been designed to conduct the bending, flexural strength, and fatigue tests on 96 concrete beams. The results showed that, compared with ordinary concrete beams, the resistance of prestressed concrete beam to bending deformation was greatly enhanced. For the beams subjected to the vertical load with increasing prestressing force, however, the deflection of the beams was decreased by a minor degree while both of their tensile stress and tensile stress area showed a sharp decrease. Moreover, the flexural strength of the concrete showed an evident increased with verified degrees while both the numbers and the width of cracks generated at the bottom of specimens decreased significantly. The average fatigue life of the prestressed concrete beams was extended 3 to 6 times longer than that of the ordinary concrete beams depending on the increasing levels of prestressing force. In general, the bending fatigue life of the prestressed concrete beams follows the two‐parameter Weibull distribution with a correlation coefficient greater than 0.96. Based on this Weibull distribution, a double‐logarithmic fatigue equation among three parameters, that is, the survival rate P, the stress level S, and the fatigue life N has been developed.

“…These two types of pavement methods generally have opposite characteristics and are selectively applied according to environmental conditions such as external load and soil profiles. On the other hand, semirigid pavement, which can complement the advantages and disadvantages of asphalt and concrete pavement, has been studied [7][8][9] by a number of researchers since it was first applied to airport pavement in France [10]. In Korea, semirigid pavement has been studied since 2001 and various studies [11,12] have been conducted to improve its performance.…”

Mechanical tests were carried out to evaluate the influence and effects of fluidity and compressive strength of cement grout on semirigid asphalt pavement. An open graded asphalt skeleton was designed in order to achieve target porosity in the range of 18∼22%. In addition, four types of cement grout mixtures were produced with varying mix proportions with ultrarapid hardening cement and chemical admixtures, that is, accelerating and retarding agents. For the semirigid pavement specimens, mechanical experiments to measure properties such as porosity, flexural strength, Marshall stability, and wheel tracking resistance were carried out. The test results demonstrated that the flow time (fluidity) of cement grout is the most significant factor that determines the mechanical properties of semirigid asphalt specimens under constant condition of the open graded asphalt skeleton. For the semirigid pavement mixing proportion in the current study, it is recommended that the porosity of the open graded asphalt skeleton and flow time of cement grout should be 20% and within 12 seconds, respectively.
