MS-2型微表处工艺是国内外路面预防性养护重要的新技术,通过对1cm厚和1.2cm厚MS-2型微表处的工艺特点和补充定额的研究,以实测法和计时法等为基础进行定额测算。结果表明,北京地区微表处的工作内容有着明显的特点,施工工艺逐渐统一,人工、材料、机械台班的消耗比较相近,确定了定额的13项构成内容。并且经定额基价测算,符合实际情况,研究成果可为微表处施工造价确定提供参考和借鉴。
The MS-2 micro-surfacing technology is an important new technology for preventive maintenance of pavement both at home and abroad. Through the research on the process characteristics and quotas of MS-2 micro-surfacing 1cm thick and 1.2cm thick, As the basis for quantitative estimates. The results show that the work content of micro-surfacing in Beijing has obvious characteristics, and the construction technology is gradually unified. The consumption of labor, materials and mechanical work-sets are relatively similar, and the 13 components of fixed quotas are determined. According to the actual situation, the research result can provide reference and reference for the construction cost of micro-surfacing.
