Compactability Analysis of Soil-Rock Mixture Linping Yu1, a and Zhiyun Wang*2, b 1College of Ocean and Civil Engineering, Dalian Ocean University, Dalian, Liaoning 116023, China 2College of Ocean and Civil Engineering, Dalian Ocean University, Dalian, Liaoning 116023, China aylp@dlou.edu.cn, bdlutwzhy@163.com Keywords: soil-rock mixture, compactability, compactability influenced factor Abstract.
As a common soil type in mountainous and hilly areas, SRM is characterized by the mixture of soil grains with different grain sizes, and its use becomes increasingly wide in civil engineering [1, 2], such as dam embankment, soil-rock dam, and other water conservancy engineering; road embankment, road bed, and other highway engineering.
Such earth and rock engineering are inseparable from the soil compaction, and compaction is an important step to ensure project quality of soil-rock filling engineering.

Actually, discarded tires can be used in soil improvement, such as flood prevention of hydraulic engineering and reinforcement of civil engineering.
Based upon previous successful utilization of tires for erosion control structures, the Department of Agricultural and Biosystems Engineering at the University of Arizona with the Department of Civil Engineering at the Technological Institute of Nogales led to designs for “retaining walls” and stair-stepped “tire mats” for slope stabilization using waste tires.
