Abstract
The paper deals with the problem of cracking of cement-stabilized macadam base course,coming forth easily under the condition of moisture changing in the south area of Suzhou.One and two cycles experiments of dry shrinkage were done.Dry shrinkage deformation properties of cement-stabilized macadam and influencing factors were analyzed.Test result offers foundation for improving the gradation composition of cement-stabilized macadam,improving its shrinkage properties.
