“…According to several studies, when meeting the minimum thickness requirement of 20 cm, the thickness of prestressed concrete pavements can be reduced to 40–60% of the ordinary concrete pavements while their life span expand five times longer. So, this technique can effectively enhance the fatigue resistance of concrete pavements …”

“…effectively enhance the fatigue resistance of concrete pavements. [5][6][7][8] Besides being used for the construction of high-grade concrete pavements, the prestressing technique can also be combined with the assembling-type pavement technique for both the quick repair of local pavements and the quick overall construction of emergency airport pavements. The emergency airport pavements are of particular practical significance for the transport of humanitarian relief goods after a disaster, the construction of frontline airfields in a war, and the building of permanent airfields under other unfavorable conditions.…”

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.

“…According to the literature on rapid damage repair, expeditious repairs are associated with shorter pavement life. However, a promising expeditious rehabilitation of pavement strategy is the effective usage of modular pavement technologies, principally precast concrete pavement system (Tayabji et al 2013). Precast concrete panels are systems that require little or no field curing time to achieve strength before opening to traffic since they are fabricated off the site, transported to the site, and installed on a prepared foundation (Federal Highway Administration 2010).…”

Utilization of the precast concrete slabs can potentially provide expeditious solutions for repairs of damaged rigid pavements. The work presented in this paper was performed mainly to analyze the influence of temperature variation during one day in the performance of three installation techniques using two different leveling materials. The synergistic influence of material properties and construction techniques on the performance of the repaired sections were evaluated by comparing three identical repaired patches installed differently with no traffic prior to testing. The repaired patches were subjected to Heavy Weight Deflectometer (HWD) for back-calculations of the layer moduli and the orthogonal load transfer efficiencies at the two sides of joints for all permutations of the experiment design. Analysis of load transfer efficiencies between the repaired sections and the pre-existing slabs at different temperatures provided valuable insight on the temperature sensitivity and load transfer devices importance in the performance of the repaired sections.

“…Several syntheses (Olidis et al, 2009;Priddy et al, 2013a;Tayabji et al, 2013) are available in the literature. The main advantage of precast concrete is that elements can be constructed and cured prior to placement, alleviating the need for long closure periods to allow for curing of cast-in-place materials.…”

“…The main advantage of precast concrete is that elements can be constructed and cured prior to placement, alleviating the need for long closure periods to allow for curing of cast-in-place materials. The place and use advantage has led to the widespread use of precast technology by the transportation community for bridges and other applications; however, only recently has the US highway sector begun to accept and use this technology for pavement applications (Tayabji et al, 2013). While few precast pavement applications for airfields are reported in the literature, successful implementation by the highway industry and results of recent airfield investigations (Bly et al, 2013;Olidis et al, 2009;Priddy and Tingle, 2014) indicate that this technology is also suitable for airfield repairs.…”

This paper examines the mechanical response of precast panel pavement repair joints under static aircraft loadings using the finite-element method. Three-dimensional finite-element models were developed using the Abaqus software code, and their results were compared to and validated against results of full-scale field tests and theoretical calculations. Unlike previous pavement repair modelling efforts for precast panels and dowel retrofitting studies, all parts of the repair joint were modelled, including the dowels, dowel slot material, parent concrete, precast panel and pavement sublayers. Results show that high stress concentrations occur in the dowel slot material and that the current panel design is likely to be improved by modifying the dowel diameter.
