摘　　要：石灰土是道路工程施工中最常用的材料,它是用生石灰(含钙量>70%)、粘土或亚粘土,按重量比,经洒水、搅拌、闷料、碾压后结成板体而形成的材料。初期石灰土对土路基能起到稳定作用,后期随着龄期增长可增大强度板体性和水稳性。简要介绍了道路用石灰土强度形成机理,施工中石灰、水、土的质量及配比要求,碾压、养生等过程对石灰土强度的影响。The lime soil is the most in common use material in road engineering, is adopt a calcium oxide （contain amount of calciumS70%） with glue soil or second glue soil, press the weight ratio, after sprinkling water, mixing blend, stuffily anticipate, Nian press become a plank body. Canned have stability function to the soil roadbed in the early years, expected to expect to increase and can enlarge the strength plank body and water steady along with the age behind. This text simply introduced road to use the mechanism of the lime soil strength formation, the quality of under construction lime, water, soil and go together with to compare to request, the Nian press, health etc. , the influence of the process upon the lime soil strength.
