在半刚性基层上加铺稀浆封层是一种成本相对较低,而实际防水效果又好的技术措施。采用稀浆封层作为封层,与其他材料封层相比较具有以下优点: 良好的防水性能。由于稀浆混合料采用细密级配,而沥青用量又比较高,混合料密实度高、空隙率小,能有效地阻止水的下渗。与基层良好的粘接性。稀浆摊铺时,只要基层表面清扫干净,并适当加以湿润,稀浆就能与基层形成良好的粘结。这 In the semi-rigid base paving slurry seal is a relatively low cost, and the actual waterproof effect and good technical measures. The use of slurry seal as a seal, compared with other seal material has the following advantages: good water resistance. As the slurry mixture with a fine grading, and the amount of asphalt is relatively high, the mixture of high density, porosity, can effectively prevent the infiltration of water. Good adhesion with the grassroots. Slurry paving, as long as the primary surface clean, and appropriate to be wet, the slurry can form a good bond with the grassroots. This
