Filling Technology and Disease Prevention Technology Research on Highway Rock Salt Embankment
2012
The engineering properties of rock salt in the salt lake region were studied by the geotechnical investigation, physical and mechanical tests and microstructural scanning. The results showed: the rock salt had many characteristics such as thicker layer, higher salt content, larger solubility, quicker leaching rate and easier dissolveing softening; natural rock salt close-grained microstructure and high limit compressive strength; rock salt did not soften and had smaller residual strain, which proved that rock salt was a suitable embankment packing in cyclic loading. Filling technology and disease prevention techniques of rock salt embankment are raised by combining new construction of the Qarham - Golmud highway and paving test road of rock salt embankment.
