Research on Dry-Shrinkage Performance of Cement-Treated Base Materials
Shrinkage cracks are easy to occur in cement-treated macadam base when temperature and humidity change. In order to study the drying shrinkage and cracking performance of different cement-stabilized macadam base materials, dry-shrinkage performance tests were carried out by mixing the cement-stabilized macadam mixture with different gradations and cement dosages, ranging from 2% to 5%. Hence, a model for evaluating the dry-shrinkage performance of cement-stabilized macadam mixture was made on the basis of the mixture's dry-shrinkage performance's relationship with water loss rate, exposure time, cement dosage, gradation and other elements. The experiment shows that the mixture's dry-shrinkage performance is the best when mixed with fine gradations and the cement is added by 3% to 4%.
