合(肥)六(安)公路改建工程是一九七五年动工的。由于冬季施工,加上辗压机具不足。不少填方地段没有很好压实,造成路基松软、强度不足。在这样的路基上直接铺筑路面存在着较多的困难。我们在两年来的施工实践中、通过不断地摸索和试验,初步取得了一些处理这样路基的认识和体会,现介绍如下,供同志们商讨。
Hop (fat) six (Ann) highway reconstruction project was started in 1975. Due to winter construction, coupled with lack of rolling equipment. Many fill lots are not well compacted, resulting in soft subgrade, lack of strength. There are many difficulties in paving the road directly on such subgrade. In the past two years of construction practice, we have made some preliminary understandings and experiences in handling such roadbeds through constant exploration and trial. We will introduce them as follows for discussion by our comrades.
