“…Arooran S. et al (2018) [11] developed measures to minimiza the early-age fatigue damage of prematurely-opened cement-treated due to repective heavy traffic loading. Jianming [12] accelerated pavement testing and a finite element method were employed to investigate the effects of three influential factors: temperature, interface bonding, and load level. In the process of cement concrete pavement maintenance, a fatigue model suitable for cement concrete and polymer is proposed, and the failure test of the cyclically moving on the road slab is involved.…”

“…Kai Liu et al (2019) [5] researched that the rigid polyurethane grout materials with different densities show elastoplastic or atypical brittle characteristic, which will significantly affect their performance. Although the polyurethane material [6] has a significant repair effect on the voids beneath the cement concrete slabs, there is still no theoretical research on the timeliness of the overall performance recovery of the pavement after repairing, fatigue damage analysis and life recovery prediction. In this paper, for the cement concrete pavement with void under slab, the stress and strain mechanical response analysis of the slab before and after grouting is firstly carried out, and then the fatigue constitutive model of four materials: concrete, polyurethane foam [7][8], cementitious, steel, is respectively established [9], introduced into ABAQUS finite element simulation software by UMAT subroutine programming [10], calculate the size of the damage factor [9], analyze the performance improvement and life extension of the pavement before and after grouting repair.…”

After the appearing of voids beneath cement concrete slabs, the pavement loses a continuous and uniform lower support structure, and the stress state of the road panel is extremely unfavorable. The polymer grouting repair is timesaving, efficient and pollution-free. In order to verify the performance improvement and fatigue damage evolution of cement concrete pavement before and after grouting repair, a material damage constitutive model was established. The UMAT subprogram was introduced into the finite element software ABAQUS to analyze the structure under the action of moving cyclic loading, stress response and fatigue damage evolution process before and after regional grouting repair. The results show that the Mises stress and vertical displacement of the grouting repairing slab are very close to the normal state, which indicates that the grouting repair has a prominent influence on the bottom void of the slab. With the rise of loading time, the fatigue damage of the pavement structure is increasing, but the trend is gradually reduced, and the number of load times and the degree of fatigue damage are nonlinear. From the long-term cyclic loading and comprehensive analysis of the construction period, the polymer grouting repair is better than cementitious grout.

“…e interface bonding between Portland cement concrete (PCC) pavement and hot-mix asphalt (HMA) overlay is widely recognized as one of the most critical influence factors on mechanical responses of composite pavement as well as its long-term performance [1][2][3]. Several studies have revealed that a weak interface bonding strength will undoubtedly cause higher bending stress, shear stress, and deflection in the composite pavement, resulting in some unexpected pavement distresses [3,4]. In the worst case, the HMA overlay might encounter problems such as slippage cracking, delamination, or severe rutting [5][6][7][8][9][10].…”

The interface bonding between Portland cement concrete (PCC) pavement and hot-mix asphalt (HMA) overlay plays an important role in the performance of the composite pavement. This research conducted a series of comprehensive laboratory studies to investigate the influence factors of the interface bonding strength using a self-designed direct shear test apparatus that can simultaneously apply normal stress and shear stress on a specimen. Four kinds of commonly used tack coat materials were systematically tested and compared under various combinations of normal stress and temperature. Then, coupling effects of the normal stress and temperature on the interface bonding between PCC and HMA were analyzed. The test results show that temperature has a significant impact on the adhesion of the tack coat. Emulsified asphalt was considered the optimal tack coat material because of its simple construction method. In addition, it was found that a damaged interface could still provide considerable bonding strength. Normal stress generated by traffic loads was beneficial to the interface bonding strength, especially at lower temperatures. The temperature had a significant effect on interface bonding and played a leading role in the failure mode of interface bonding.

“…The finite elements method is the most widely used, as a result of its excellent computational accuracy. Many general-purpose finite element packages have attracted the attention of engineers, such as ABAQUS and ANSYS [ 18 , 19 , 20 , 21 , 22 ]. Besides this, a series of sub-processors were developed in order to satisfy special purpose, such as KENSLABS [ 23 ], EverFE [ 24 ] and ISLAB2000 [ 25 ].…”

Uneven support as result of voids beneath concrete slabs can lead to high tensile stresses at the corner of the slab and eventually cause many forms of damage, such as cracking or faulting. Three-dimensional (3D) finite element models of the concrete pavement with void are presented. Mesh convergence analysis was used to determine the element type and mesh size in the model. The accuracy of the model is verified by comparing with the calculation results of the code design standards in China. The reliability of the model is verified by field measurement. The analysis shows that the stresses are more affected at the corner of the slab than at the edge. Impact of void size and void depth at the slab corner on the slab stress are similar, which result in the change of the position of the maximum tensile stress. The maximum tensile stresses do not increase with the increase in the void size for relatively small void size. The maximum tensile stress increases rapidly with the enlargement in the void size when the size is ≥0.4 m. The increments of maximum tensile stress can reach 183.7% when the void size is 1.0 m. The increase in slab thickness can effectively reduce maximum tensile stress. A function is established to calculate the maximum tensile stress of the concrete slab. The function takes into account the void size, the slab thickness and the vehicle load. The reliability of the function was verified by comparing the error between the calculated and simulated results.
