R34类材料在填方中应用的可行性,目前并未获得一致公认,许多国家有泥灰岩材料的使用经验,但也出现了许多失败的案例。阿尔及利亚东西高速公路的承包商们为此进行了许多的分析和试验。以M5标段为例,从地质条件、试验室试验结果、GTR要求、试验路段成果等方面,对泥灰岩挖方类材料的再利用的可能性进行了分析和研究,最终确定废弃R34类挖方材料。 The feasibility of using R34 materials in fillings has not been universally acknowledged. Many countries have experience in the use of marl materials, but many failed cases have also emerged. Contractors of the Algerian motorway east-west carried out a great deal of analysis and experimentation. Taking the section M5 as an example, the possibility of recycling the marl material is analyzed and analyzed from the aspects of geological conditions, laboratory test results, GTR requirements and test road results. Finally, the waste R34 excavation material.
