摘要：
This study focused on the current situation and application examples of the solar pavement technology across the globe. The development trend and application potential of this technology were analyzed systematically in terms of surface structure, load-bearing capacity, road performance, security and the integrated smart control function. The technological difficulties and research directions were then proposed. After that, the recommendations for further progress in the technology are provided, giving suggestions on the development of the solar pavement technology in China.

摘要：
The use of thin asphalt overlay is an effective way in preserving and maintaining the road surface. In this study, the virgin asphalt was mixed up with Superflex modifier at varied concentrations to get the modified asphalt overlay, and the optimum modifier content was 15% by weight of the total mix. Aggregate gradation of the overlay was acquired by means of volume method, and the optimal asphalt content was obtained through Marshall mix design. The performance of the modified overlay mixture evaluated in the laboratory included high-temperature stability, moisture susceptibility and skid resistance. In order to investigate the effects of different thickness levels and structure patterns, four thin overlay sections were paved on route G321 in Guangdong, China. Deflection, skid resistance, permeable performance and roughness were inspected four times in the following six years. The laboratory test results showed that all the testing indices satisfied the criteria specified in China. The field inspection data proved that the thin asphalt overlays evaluated in this study performed well in terms of skid resistance, permeable performance and roughness in every section, without sharp damage on the surface. It can be concluded that the Superflex modified asphalt mixture can be used as thin overlay and this technology is worth popularizing.

摘要：
Laboratory rutting tests for AC20 under the condition of different temperatures (30°C, 45°C and 60°C), wheel pressures and wheel running speeds were carried out with an improved wheel rutting tester whose wheel running speed can be adjusted. The test results show that (1) the rut index value of AC20 under the condition of 45°C, heavy loading and low speed can be inferior to that under the condition of 60°C, standard loading and standard speed; (2) it is difficult to induce rut for the AC20 at 30°C even under the condition of heavy loading and low speed. The analytic result indicates that not only the rutting due to variable high temperature but also the rutting due to medium temperature combined with heavy loading and low speed should be considered to study the rutting deformation of asphalt pavements in cold area. Therefore, it is suggested to improve the laboratory rutting test method for cold area by introducing the testing condition of heavy loading and low speed besides changing the testing temperature from 60°C to 45°C according to the traffic condition.

摘要：
First, the axle-load skid-resistance conversion formula of asphalt pavement was established in accordance with the equivalent principle of skid-resistance performance attenuation which is similar to the way of axle-load equivalent conversion for asphalt pavements structure design. The way to determine the axle number coefficient and wheel number coefficient was also proposed. Second, the prediction method of skid-resistance life of asphalt pavement was put forward on the basis of the axle-load skid-resistance equivalent conversion formula. Afterwards, the skid-resistance performance attenuation tests for asphalt mixture SMA16 were carried out on a selected expressway under various wheel pressures. Finally, by using the deduction of fatigue equation of asphalt mixture for reference, the skid-resistance fatigue equation for SMA16 based on BPN value was derived to predict the skid-resistance life of the expressway pavement. The results indicate that it is feasible to study skid-resistance performance of asphalt pavements with the skid-resistance performance of equivalent conversion method.
