Abstract: To develop a purely inorganic fire-retardant-modified asphalt, we selected highly fire-retardant materials that have low-carbon content, non-polluting properties, and are inexpensive as fire retarder of asphalt. The optimal ...

Abstract: An optimal design method for the main bearing of a tunnel boring machine is proposed. In this method, the fatigue life is used as the objective function. Structural parameters, including clearance, are considered as design ...
