Shrinkage cracks in cement-stabilized macadam base are seriously influences performance of asphalt surface. Setting about cracking mechanism for transverse shrinkage crack for cement-stabilized macadam base, combined with theoretic analysis and outdoor test method, we shall study for the method for reduction of base crack. Samples with different dosage of cement were selected from test road, as well as select out corresponding parameter to make calculation. Analysis for finite element and outdoor test result indicated that suitable reduction for cement dosage and improvement for construction workmanship shall effectively reduce in crack creation for cement-stabilized macadam base.
