Durability and performance of bituminous geomembranes

沥青土工膜是传统聚合物土工膜的重要替代品，用于垃圾填埋场和泻湖屏障、废物覆盖物、土坝的防水以及岩土工程中需要不可渗透屏障的各种其他用途。 与常规聚合物相比，关于BGM的相对耐久性的信息有限。 特别地，根据温度，通常认为抗穿刺性更高，但是缺乏可靠的测试数据。 该项目旨在作为生成可靠性能数据数据库的第一步，在该数据库中，各种BGM产品可以直接与广泛使用的传统聚合物产品进行比较。 这样做的目的是，有了这些可靠的数据，岩土工程师将有一个合理的基础上，考虑替代产品的具体项目的基础上，产生的好处方面的资本节省项目和改善废物遏制和保护环境。

Bituminous geomembranes represent an important alternative to conventional polymer geomembranes that are used for landfill and lagoon barriers, waste covers, waterproofing of earthfill dams and various other uses in geotechnical engineering where an impermeable barrier is required. Limited information exists regarding the relative durability of BGM compared with conventional polymers. In particular puncture resistance is often assumed to be higher, depending on the temperature, but there is a lack of reliable test data. This project is intended as a first step in generating a database of reliable performance data in which various BGM products can be compared directly with the conventional polymer products that are widely available. It is intended that with the availability of such reliable data, geotechnical engineers will have a rational basis on which to consider alternative products on a project-specific basis, with resulting benefits in terms of capital savings to a project and improved waste containment and preservation of the environment.
