Pavement Friction

To overcome the limitations of pavement skid resistance prediction using the friction coefficient, a Genetic-Algorithm-Improved Neural Network (GAI-NN) was developed in this study. First, three-dimensional (3D) point-cloud data of an asphalt pavement surface were obtained using a smart sensor (Gocator 3110). The friction coefficient of the pavement was then obtained using a pendulum friction tester. The 3D point-cloud dataset was then analyzed to recover missing data and perform denoising. In particular, these data were filled using cubic-spline interpolation. Parameters for texture characterization were defined, and methods for computing the parameters were developed. Finally, the GAI-NN model was developed via modification of the weights and thresholds. The test results indicated that using pavement surface texture 3D data, the GAI-NN was capable of predicting the pavement friction coefficient with sufficient accuracy, with an error of 12.1%.

Pavement Surface

With China's rapid economic development, transport markets are booming. High way, especially expressway plays a very important role in economic development of today. Asphalt pavement surface is widely used. And with the development of expressway, more and more recycled asphalt concrete will be produced. So how to deal with these waste materials becomes a focus problem among researchers. In this paper, aging rules of asphalt according to the engineering practice and test data was talked about. The aging can be divided into: aging during transport, storage, and heating, aging during hot-mixing and paving, aging during the operation of the pavement. At the same time, the general knowledge about the regenerated asphalt was discussed. In addition, the possible damage of RAP technique to environment was also discussed.
