Abstract: Inadequate skid resistance of pavement surface is a substantial reason for traffic accidents. There is a close relationship between sliding resistance and characteristics of texture morphology, demanding high precision and ...

Abstract: Due to variations in freight traffic arising in daily operations, railways need to develop a distribution plan to determine the actual movements of empty cars every day. This paper investigates the daily empty car distribution ...

Abstract: Theory of operations research is applied in this paper. The minimum total cost of steel reinforcement work was used as the objective function, and a three-step mathematical model to optimize the rebar cutting-stock was ...

Abstract: In order to study the influence of aggregate types on the long-term skid resistance of asphalt pavement, six different types of aggregates such as arkose, red sandstone, limestone, basalt, diabase, and granite were selected. ...

Abstract: 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 ...

Abstract: The soil microbial community is highly sensitive to the soil environment and can reflect changes in soil quality and soil ecosystem health. To clarify the differences in microbial structure and the effect of environmental ...
