The road subgrade and surface in collapsible loess area are prone to many engineering diseases such as uneven settlement, insufficient bearing capacity of soaked foundation, collapse instability side slope due the special properties loess. As an environment-friendly, low-cost soil modifier with good adhesion chelation properties, lignin has been considered be used highway construction. In order...

The role that the pattern of vessel wall growth plays in determining pressure-lumen area (P-A) and pressure-compliance curves was examined. A P-A vessel model was developed that encompasses the complete range of pressure, including negative values, and accounts for size given the fixed length, nonlinear elastic wall properties, constant wall area, and collapse. Data were obtained from excised c...

In the last five decades, rise of plastic industry led to increase in waste environment, therefore scientists were thinking reduce by recycling plastic. On other hand, there is a problem collapse gypseous collapsible soil upon wetting. this paper, one methods adopted improve mixing with 1% fiber shear strength and collapsibility at state saturation or The used classified as SW-SM, gypsum conten...
