不易风化的块石碴料(下称碴料)是填筑路堤的良好填料,已为越来越多的工程技术人员所接受。但是由于这种碴料只能在石山开采时获得,所以在道路工程中不便普遍采用。只有当这些填料成为其它工程的弃料时,才得以运用。另外目前现行的路基设计、施工规范对这种填料的规定不够详尽,尤其对施工过程中的质量控制标准尚无明确规定。也是这种填料用得不多的原因。作者通过深圳机场立交工程采用碴料填筑高路堤的实例,提供参考
Not easy to weathering block ballast material (hereinafter referred to as ballast material) is to fill a good embankment filler has been accepted by more and more engineering and technical personnel. However, this kind of ballast can not be commonly used in road construction because it can only be obtained at the time of mining. It is only when these fillers are used as rejects for other projects. In addition, the current subgrade design and construction regulations do not provide sufficient detailed rules for such packing materials. In particular, there is no clear stipulation on the quality control standards in the construction process. This filler is also used for a small reason.
