“…The influence of water on road structure over an annual cycle is always substantial and is multivariate in nature. Paper [2] proposed an analytical solution to determine the amount of water removed by the drainage layer of a road base. The authors gave recommendations on the use of materials in drainage layers depending on their filtration properties.…”

“…The dynamic load acting on the pavement structure has two components: (1) changes in the location where the force is applied and (2) changes in the magnitude of the force. The dynamic load acting on the pavement structure is often classified into the following three classes: the moving load, the impact load, and the random load [20]. The random load is the closest to the true load situation on the pavement, but it is relatively difficult to simulate.…”

This paper establishes the equivalent relationships between the half-sinusoidal load, triangular load, vertical stepwise load, and moving traffic load. The governing equation was established for analyzing the dynamic responses of pavement, and half-sinusoidal load, triangular load, and vertical stepwise load functions were transformed into Fourier series expressions. The partial differential governing equations were simplified as ordinary differential equations and the analytical solutions were obtained. Further, the solutions were validated through comparing the theoretical results with numerical simulated results. Calculation results revealed that, for unchanged load periods, increasing the amplitudes of the three loads by 1.06, 1.31, and 1.35 times can better simulate the moving traffic loads. For unchanged load function amplitudes, increasing the function periods by 1.07, 2.23, and 2.1 times (for half-sinusoidal, triangular, and vertical stepwise loads, resp.) can improve the simulation performance. The fatigue life of asphalt pavements under the moving traffic load agrees with that of the three load simulations, indicating that the fatigue life of asphalt pavements is only associated with the load amplitude but not the load patterns.

“…The performance of asphalt mixture-paved bridges is affected by the asphalt compaction quality. Poorly compacted asphalt pavements may suffer defects such as cracks, ruts, and water damage [6][7][8]. Such defects may compromise express highway performance and are a major cause of traffic accidents [9].…”

Vibratory compaction of bridge deck pavement impacts the structural integrity of bridges to certain degrees. In this study, we analyzed the dynamic response of different types of concrete-beam bridges (continuous beam and simply supported beam) with different cross-sectional designs (T-beam and hollow-slab beam) under vibratory compaction of bridge deck asphalt pavement. The dynamic response patterns of the dynamic deformation and acceleration of bridges under pavement compaction were obtained by performing a series of field experiments and a three-dimensional finite element simulation. Based on the finite element model, the dynamic responses of bridge structures with different spans and cross-sectional designs under different working conditions of vibratory compaction were analyzed. The use of different vibration parameters for different bridge structures was proposed to safeguard their structural safety and reliability.
