Filling Technology and Disease Prevention Technology Research on Highway Rock Salt Embankment

Abstract:

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.
