Abstract :
During the process of asphalt foaming, the control of spraying synchronism and fluid ratio of asphalt and water is the key to the quality of foamed asphalt. Newtonian fluid and nonNewtonian fluid´s pipeline dynamic characteristics are studied by utilizing the sectional concentrated parameters modeling which including the dynamic friction item. To spraying water and asphalt in different pipes, the time cost is different. The asphalt viscosity also affects the flow in pipeline. These factors can provide theoretical instruction for developing asphalt foaming system. They can also guide the accurate measurement and control of asphalt and water. A new method of flow matching between varied viscosity fluids is also presented.
