Micro-Surfacing Troubleshooting Details/微表处问题解决方法的具体内容
• Materials/材料 – Emulsion (save for last)/乳化沥青(最后解释) – Aggregate/石料 • Changed aggregate source – mineralogy change reacts differently with a given emulsion/mineral filler system resulting in lack of work time or slow curing (micro emulsions are not “one size fits all”)/变换料源 – 石料岩性变 化使和特定乳化沥青/矿料及矿粉系统反应发生变化,进而导致 缺乏拌合时间以及养护时间变长(微表乳化沥青不是“一个乳 化沥青适合所有系统”)

Micro-Surfacing Troubleshooting Motivation/解决微表处问题的动力
When EVERYONE cooperates in finding the cause of the problem, the amount of down time is minimized/当我们每个人齐心 协力合作找出问题的原因时,停机的时间将 被减到最小。

Micro-surfacing Troubleshooting Method/微表处问题解决的方法
• The big question is “What changed?”/关键问 题……“有改变的地方吗?” – “Weபைடு நூலகம்have been laying this stuff for 3 years, we haven’t changed anything, but suddenly it is not working”/“我们已经利用现在的材料进行微表处 施工3年了,没有改变过任何东西,为什么突然不行 了呢?”
