“…Repeated uniaxial compression tests were carried out on PFC-13 specimens under a nonseepage eld and a seepage eld. Based on (10), the damage factors were calculated, as shown in Figure 12. For the same number of repeated uniaxial compression cycles, namely, 2 million cycles, the damage factor was about 0.006 for the nonseepage eld, but the damage factor was about 0.025 for the seepage eld.…”

“…Kringosn et al [9] believed that water intruded into the gaps between the asphalt and aggregate and produced a pumping e ect under a load, resulting in water damage, and they established a uid-solid coupling model based on this. Si et al [10] established a viscoelastic constitutive equation of asphalt and a nite element model of asphalt pavement, deduced the stress seepage coupling equation of asphalt pavement, and veri ed the e ectiveness of the model. Ding and Wang [11] analyzed the mechanical response of saturated asphalt pavement under the coupling of a seepage eld and a stress eld.…”

In order to study the variations of the non-Darcy flow permeability coefficient and the porosity of permeable friction courses (PFCs), as well as the effects of the coupled seepage and stress fields on them, repeated uniaxial compression tests were carried out under the coupled action of water and a load. A set of water and load coupling tests were conducted, and a non-Darcy flow permeability coefficient tester was also made. After the PFC-13 specimen was carried out by the repeated uniaxial compression test under the water and load coupling, the total air void ratio and effective air void ratio were measured by the vacuum sealing method, and the non-Darcy flow permeability coefficients were obtained by a non-Darcy flow permeability coefficient tester. It was found that the coupled action of water and a load caused the total air void ratio, effective air void ratio, and permeability coefficient to sharply increase and reduced the number of repeated uniaxial compression cycles. These results are helpful for the design, construction, and maintenance of PFC mixtures.

“…In order to study the change law of pore water pressure in asphalt pavement, studies about numerical calculations and theoretical analyses have been carried out to calculate the pore water pressure [8][9][10][11][12][13]. For example, based on the porous media theory and Biot theory, Sun et al [14] built a hydromechanical coupling model to investigate the spatial distribution and the change law with time of pore water pressure in asphalt pavement.…”

To investigate the flow characteristics of pore water in asphalt pavement and the variation law of the pore water pressure under vehicle loading, a novel method based on BA network and quartet structure generation set method was proposed to reconstruct the three-dimensional (3D) pavement model with pores. The permeability coefficient and the gradation curve were adopted to evaluate the reliability and stability of the random growth pavement model. Then, the tire-fluid-pavement coupling model was established with FLUENT 3D based on the fluid Mie–Gruneisen state equation. According to the built fluid-solid coupling model, the pressure-velocity coupled finite volume algorithm was applied to study the distribution of the pore water pressure in asphalt pavement. Results show that the pore water pressure in asphalt pavement decays periodically with time under vehicle loading. For different types of asphalt pavement, the pore water pressure in open-graded friction course (OGFC) pavement is the smallest during the whole process. Moreover, the peak values of the pore water pressure decrease in the order of asphalt concrete (AC) pavement, stone mastic asphalt (SMA) pavement, and OGFC pavement. The maximum negative value of the pore water pressure is generally less than 0.3 times the maximum positive values. As for saturated pavement pores, the pore water pressure is hardly affected by the water film thickness. The positive peak value of the pore water pressure increases on an approximate parabolic curve as the vehicle speed improves gradually, while the negative one remains largely unchanged. The results are expected to help reduce tire hydroplaning risk and provide guidance for the selection of asphalt mixtures of drainage asphalt pavement.

“…The key factors which might affect damage of the pavement were simulated and analyzed (Xue et al, 2013). Si et al (2019) analyzed pore water pressure of a pavement structure under rainfall infiltration and determined thermal stress using the Abaqus software. The longitudinal stress, vertical stress, shear stress and transverse stress of different structural layers were calculated and analyzed under the multi-field condition.…”

The purpose of the study was to evaluate the effect of interlayer bonding conditions on the mechanical performance of a synthetic sports track with time. A two-dimensional finite element model of the synthetic sports track was developed in order to calculate the track temperature stress and strain in thermal environmental conditions. Thermal and structural responses of the multi-layer sports ground were simulated using a transient thermal and structural analysis in one day. Based on that, different physical parameters of the interlayer were considered to analyze the influence of the bonding layer status on the potential damage of the surface layer in the sports track. The results indicated that different bonding conditions would affect the strain difference between the top and bottom of the synthetic sports layer, which might cause a weak mechanical performance of the synthetic sports layer. Finally, 2D finite element analysis was regarded to be a proper tool to simulate the transient thermal and mechanical behavior of the synthetic sports track. The suggested simulation model can predict the influence of bonding conditions on damage of the synthetic sports track, which can provide some guidance for engineers and technicians working on constructions of synthetic sports tracks.
