“…Coverages can be defined as the number of repetitions of the maximum strain before failure. The number of coverages to rutting failure is defined in FAARFIELD 1.41 by a bilinear model (Equation 6) (15) and fatigue failure is defined based on the ratio of dissipated energy change (RDEC) model (Equation 7) (16). Since the number of coverages can differ from the number of passes because of aircraft wander, a C/P ratio needs to be computed.…”

Changes in climatic conditions can directly affect pavement performance. However, accounting for environmental factors in airport pavement design remains a challenge since design methods such as FAA rigid and flexible iterative elastic layered design (FAARFIELD) do not consider moisture and temperature variation as input. Therefore, to address this research gap and improve the resilience of airport pavements, this research proposes a new methodology for the structural design of flexible airport pavements. The proposed methodology in this research was applied to a case study of an international airport in Canada, using actual field data. Five scenarios were evaluated including the current climate, temperature increase, lower matric suction, and two flooding events. The results of the proposed design method showed that the traditional FAARFIELD analysis can possibly overestimate fatigue damage, and underestimate rutting damage. The outcomes showed that climate change can increase pavement damage and shorten the service life from 7 to 14 years in the scenarios evaluated. It was also concluded that the lowering of the matric suction can result in the highest damage levels. Considering the implications of climate change on transportation infrastructure, the proposed methodology can contribute to designing more resilient airport pavements in the future, since it accounts for climate variations, temperature, and moisture changes, as well as extreme events such as flooding over the design life of flexible airport pavements.

“…An illustration of the survey scheme is given in Figure 8. The FWD load was set to 100 kN, which was selected according to previous experience [8,14] in order to ensure that the concrete pavement will exhibit appropriate responses under the FWD loading. The utilized FWD sensor array is given in Table 1.…”

“…The Falling Weight Deflectometer (FWD) [6] is the most indicative NDT system for pavement evaluation. Following its efficiency for highway pavement assessment [6,7], the use of FWD is a well-structured method and constitutes the standard practice approach in airfields too [8][9][10][11][12][13][14]. Deflectometric tests are usually taken at various locations across a concrete slab, including its center, edges and corners.…”

Structural Performance Assessment of Airfield Concrete Pavements Based on Field and Laboratory Data

Maintenance interventions and rehabilitation actions in airfield pavements are time-consuming and adversely affect pavements’ serviceability (i.e., airport closures), with a profound impact on the airport economics. Once a pavement is constructed, a robust asset management prerequisites systematic and accurate knowledge of pavement condition throughout its service life. Evaluating a pavement’s structural capacity in the field involves the integration of multiple Non-Destructive Testing (NDT) systems, with the Falling Weight Deflectometer (FWD) being the most indicative NDT system for pavement evaluation. The purpose of the present study is to develop a methodology for the assessment of airfield concrete pavements. A new and non-trafficked Jointed Plain Concrete Pavement (JPCP), facing early-life cracks shortly after a runway’s expansion activities, was utilized for the investigation. Multiple types of data collected in the field, including deflections, load transfer efficiency at joints and cracks, concrete thickness through coring as well as data retrieved in the laboratory (concrete’s flexural strength), helped to define the pavement’s performance and assess its damage potential. Overall, the integration of such data can provide the related airport authorities the necessary information in order to make a rational asset management and enhance the efficiency of airfield infrastructures. The methodology is applicable for both new and in-service pavements.
