As to the pavement test, with the slip-based control method, a new pavement mobile type of measuring device was designed to obtain the continuous friction coefficient parameters in this paper. The operation principles and the concrete completion methods of slip ratio control were introduced in detail. 89C52 was adopted as the center chip to achieve the system design of hardware and software. After the pavement tests, the prototype is of high reliability, low cost, and simple operation, meanwhile, meets the requirements of pavement skid resistance.

Significant Factors

This study investigates the relationship between the density and temperature of newly placed hot-mix asphalt pavement, and attempts, using both field and laboratory-based data, to validate the theory that as asphalt cools it becomes denser. Hence, if a nuclear gauge is used to measure asphalt density, it should record a higher reading after the asphalt has been allowed to cool overnight than when the asphalt density was first measured just after cold rolling the previous day. This research investigation has found a model that does not reinforce this theory. Research has shown that testing a road for density the morning after paving, as opposed to the same day, does not result in a significant increase in density. In addition, this study found significant factors that impact pavement density, and developed an explanatory model to estimate pavement density.

Resistance Performance

The British pendulum tester (BPT) and the dynamic friction tester (DFT) are commonly used to evaluate the polishing effect of traffic on pavement skid resistance. The present study was conducted to answer two questions: (i) whether the directional moving traffic action results in significant directional differences in skid resistance of the pavement, and (ii) if so, whether BPT and DFT are effective tools for evaluating the skid resistance performance of polished pavements with significant directional skid resistance characteristics. Five in-service pavement sections with different degrees of polishing were examined in this study. The following findings were obtained from the study: (a) There were statistically significant differences between the longitudinal and transverse skid resistance of the polished pavements tested; (b) there were no statistically significant differences between the longitudinal and transverse skid resistance of the newly paved unpolished pavement tested; (c) BPT was able to differentiate the directional skid resistance differences of the polished pavements tested; and (d) DFT was unable to differentiate the directional skid resistance differences of the polished pavements tested. DFT produces one skid resistance value for a circular path at each test point. The test results found that DFT over-estimated the traffic-direction skid resistance of in-service pavements. The over-estimation errors ranged from 0.001 to 0.023 DFT units, and the corresponding percent errors were from 0.4% to 11.1%. This finding suggests that the over-estimation effect of skid resistance directionality of polished pavements on DFT measurements should be recognized in pavement skid resistance evaluation and pavement safety studies.

Abstract. Poisson’s ratio is one of the important parameters that can be used to reflect the deformation characteristics of solid materials. To further understand the mechanical behaviors of materials and improve the accuracy of the finite element simulation results, the Poisson’s ratio must be defined accurately. In this paper, DIC technology is employed to investigate the Poisson’s ratios of asphalt mixtures under the different gradation and different compaction conditions. It is found that the Poisson’s ratios of different asphalt mixture are quite different and the number of compaction had a greater influence on Poisson’s ratio. It also showed that Poisson’s ratio of asphalt mixture was not a constant under the 25°C temperature condition, but varied with load. The experiment data suggested that the curve of the load - Poisson’s ratio could be divided into three sections through the observation of the graph and it also could be used to investigate the properties of asphalt mixtures deformation resistance. General-purpose finite element software is used to simulate the different contact pressure and Poisson’s ratio under dynamic loading condition, in order to find the response of asphalt pavement structure based on the relationship between load and Poisson’s ratio. It was found that the relationship of load - Poisson’s ratio significantly affected the response of asphalt pavement. It meant that the relationship of load - Poisson’s ratio should be considered when designing the asphalt pavement to improve the asphalt pavement service life.
