Experimental Research on Engineering Properties of Natural Coarse Saline Soil as the Subgrade Filler

Abstract

Bases on the project of typical natural coarse saline soil area ,Startis from the saline soil salt expansion characteristics of seven cycles of freeze-thaw cycling test and saline soil subgrade model test ,concluses not only the oil can make roadbed fillers for highway and first-class highway directily , but provides experiences for saline land area of natural coarse particles of high highway designs and construction engineering. Meanwhile, this paper also provides reference experiences for the design and construction of high level road engineering at natural coarse saline soil regions.
