Due to resonant effects, a lot of high-rise structures could be severely damaged under long-period seismic excitations. In this study, the seismic fragility method based on incremental dynamic analysis (IDA) is employed to quantitatively evaluate the damage levels of high-rise structures under long-period ground motions. Firstly, the frequency contents of special long-period ground motions are analyzed. Then, the finite element models of high-rise frame-core tube structures are established and verified. Lastly, the IDA curve clusters, quantile curves, probabilistic demand models, exceeding probability curve and seismic fragility matrix of the structure under multi-dimensional long-period ground motions are researched respectively. The analytical results show the amplitude contents of long-period ground motions are mainly distributed in the narrow low-frequencies band. Long-period earthquake is more likely to cause structural collapse than ordinary earthquake under large earthquake intensity, and the seismic fragility analysis based on a certain exceeding probability needs to consider the adverse effect of the increased horizontal translational components. The research conclusions will provide urgently needed theoretical basis for seismic design in areas with hidden long-period earthquake damage, and it also promote the development of seismic design methods and the improvement of seismic structural measures for high-rise structures.

To study dynamic changes in pavement skid resistance, this paper presents a new decay model. The new decay model is a grey model established based on three-dimensional (3D) texture using quadratic fitting, which just requires one small sample of data. The prediction accuracy of the proposed model is examined. Additionally, the model’s prediction effect and the influence of different factors on decay characteristics are further analysed. Results indicate that the new decay model can well describe the decay characteristics of the pavement skid resistance. In terms of macrotexture, the decay rate and the terminal value both change in a favorable direction as the abrasion resistance of aggregates increases. During the decay process, stone mastic asphalt (SMA) has a minimum decay rate and a relatively large terminal value. In terms of microtexture indicators, the decay characteristics are more complex. The reason may be that the microtexture is continuously regenerated under the abrasion action during the decay process. The decay rate of asphalt concrete (AC) is low, and the terminal values of the SMA and open-graded friction course (OGFC) are relatively high. The results of this study are helpful to deeply understand the decay characteristics of pavement skid resistance, which have a guiding significance for the establishment of a decay model of skid resistance using small samples.

To improve the precision of traditional binocular reconstruction technology and better serve the traffic safety, laser line constraint was firstly introduced. Then three different matching modes, namely the default color, enhanced target line and region segmentation, were established. Finally, the improved binocular reconstruction test system and the three-dimensional texture morphology measurement accuracy evaluation device were produced. The effect of matching modes on the test precision of three-dimensional texture morphology of asphalt pavement was further analyzed. The results show that the introduction of laser line constraint improves the precision for both overall measurement and single point measurement. The improved algorithm under the region segmentation matching mode has a good reconstruction effect. The average deviation of the overall measurement is 0.02 mm, and the maximum deviation of the single point measurement is 0.14 mm, which can meet the requirements of pavement texture detection in skid resistance evaluation.

Pavement skid resistance is an important guarantee for driving safety. However, it is very difficult to determine the exact friction in a field environment. In order to overcome the limitations of traditional evaluation methods, the effect mechanism of surface 3D (three-dimensional) texture on skid resistance was firstly analyzed. Then the surface 3D texture of pavement was acquired through an improved binocular reconstruction method. Additionally, the relationship between friction coefficient and 3D texture was also analyzed. Subsequently, under the concept of IFI (international friction index) used to harmonize different detection methods of skid resistance, the evaluation model of skid resistance based 3D texture was further established. The results showed that the multiple quadratic multinomial regression model can well describe the relationship between skid resistance and texture indicators. The establishment of an improved evaluation model is simple to operate and implement. It can directly evaluate the skid resistance on pavement surface once the aggregates’ type and 3D texture are known. This evaluation model not only overcomes the challenges of friction coefficient with a strong conditional restriction, but also provides a harmonious approach for different detection methods in the evaluation of pavement skid resistance.

In order to guarantee the service performance of recycling asphalt mixture with reclaimed asphalt pavement (RAP), asphalt rejuvenator shall be added. In the last five years, vegetable oil-based rejuvenators have received more and more attention due to their green and regenerative advantages. The object of this paper is to investigate the feasibility of rejuvenating aged asphalt by a kind of waste vegetable oil (W-oil). The effect of W-oil on the performance of aged asphalt is characterized by a safety property test, aging property test, and pavement performance tests; the pavement performance tests included traditional tests and a rheological test. The results show that both the safety property and aging property of rejuvenated asphalt with W-oil meet the specification requirements. According to the results of traditional performance indexes (i.e., penetration, soften point, and ductility), the pavement performance of rejuvenated asphalt can be recovered to the level of virgin asphalt. According to the results of performance indices obtained from the rheological test, the optimum dosage of W-oil is determined to be 13.4 wt %. Compared with virgin asphalt, the rutting property of rejuvenated asphalt is equivalent to that of virgin asphalt, and the workability is slightly poorer; however, the fatigue property and low temperature property have been significantly enhanced. W-oil cannot only improve the pavement performance of aged asphalt, it can also guarantee good safety property and aging property. Therefore, W-oil is of great potential to serve as an asphalt rejuvenator for rejuvenating aged asphalt.
