| 1. | When the cement concrete pavement is opened to the traffic up to 3 ~ 5 years , especially when the wear resistance of the coarse aggregate is not good and the strength of the concrete pavement is not adequate , the wear in the original road surface will be more distinct in these cases . the phenomena of stripping , pit slot , surface pit , incompact and polish , filler damage and etc . usually happen in the cement concrete pavement . it will influence the traffic quality once the diseases appear in the cement concrete pavement 本论文结合东北高速黑龙江分公司项目《水泥混凝土路面白色薄层罩面技术的研究》展开工作,通过大量的试验研究,从以往国内的修复材料,国外的同类材料中,参考道路修复材料的技术标准,路面养护维修手册和混凝土路面修补技术要求,吸取已有材料的长处和特点,研制开发了kg水性修补材料和kg油性修补材料,通过反复测试并做正交试验,研制出最优配方。 |
