关键筛孔及施工温度下的沥青路面施工控制分析

Key sieve hole and construction temperature of asphalt pavement construction control analysis

以省道马走线马市口至瓦窑口改建工程路段为例,分析了沥青路面施工受自然气候和地理条件的影响,在施工中存在较大的难度,其中主要包括施工温度不稳定,优质集料比较缺乏,拌和料的运输距离比较远,分别从关键筛孔和热老化时间以及温度三方面对沥青路面施工质量造成的影响进行剖析,并提出了相关策略。

To go to the mouth of the line tawma Wayao Mashikou road reconstruction project as an example,analyzes the influence of asphalt pavement construction by natural climate and geographical conditions,there is a big difficulty in construction,including construction temperature instability,lack of high-quality aggregate,mixing the transport distance,respectively from the key sieve and thermal aging effect analysis of asphalt pavement construction quality caused by the time and temperature of the three aspects,and puts forward relevant strategies.
