1.1 本规程为测试经处理或整个废轮胎的物理特性、设计考虑、施工实践和渗滤液生成潜力提供了指导，以代替传统土木工程材料，如石头、砾石、土壤、沙子、轻骨料或其他填充材料。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本规程旨在使用废轮胎，包括:由废轮胎碎片、TDA/土壤混合物、轮胎侧壁和土木工程应用中的整个废轮胎组成的轮胎衍生骨料（TDA）。这包括使用TDA和TDA/土壤混合物作为轻质路堤填料；轻质挡土墙回填；道路、垃圾填埋场和其他应用的排水层；隔热以限制道路下方的霜冻渗透；隔热回填，以限制建筑物的热损失；轨道线路的减振层；以及在其他填充应用中替换土壤或岩石。使用整个废轮胎和轮胎侧壁包括建造挡土墙、排水涵洞、道路基层加固和侵蚀防护，以及在整个轮胎压缩成捆时用作填充物。 设计工程师有责任确定在特定应用中使用废轮胎的适当性，并选择适用的测试和规范，以促进施工和环境保护。本规程旨在鼓励在土木工程应用中更广泛地使用废轮胎。 4.2 厚度超过7 m的三种TDA填充物经历了严重的加热反应。然而，已经建造了100多个厚度小于3 m的填充物，没有证据表明存在有害的加热反应 ( 1. ) . 7. 已制定指南，以尽量减少TDA填充物的内部加热 ( 2. ) 如中所述 6.11 . 本指南适用于厚度小于3 m的填料。因此，该做法仅适用于厚度小于3 m的TDA填土。

1.1 This practice provides guidance for testing the physical properties, design considerations, construction practices, and leachate generation potential of processed or whole scrap tires in lieu of conventional civil engineering materials, such as stone, gravel, soil, sand, lightweight aggregate, or other fill materials. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 This practice is intended for use of scrap tires including: tire-derived aggregate (TDA) comprised of pieces of scrap tires, TDA/soil mixtures, tire sidewalls, and whole scrap tires in civil engineering applications. This includes use of TDA and TDA/soil mixtures as lightweight embankment fill; lightweight retaining wall backfill; drainage layers for roads, landfills, and other applications; thermal insulation to limit frost penetration beneath roads; insulating backfill to limit heat loss from buildings; vibration damping layers for rail lines; and replacement for soil or rock in other fill applications. Use of whole scrap tires and tire sidewalls includes construction of retaining walls, drainage culverts, road-base reinforcement, and erosion protection, as well as use as fill when whole tires have been compressed into bales. It is the responsibility of the design engineer to determine the appropriateness of using scrap tires in a particular application and to select applicable tests and specifications to facilitate construction and environmental protection. This practice is intended to encourage wider utilization of scrap tires in civil engineering applications. 4.2 Three TDA fills with thicknesses in excess of 7 m have experienced a serious heating reaction. However, more than 100 fills with a thickness less than 3 m have been constructed with no evidence of a deleterious heating reaction ( 1 ) . 7 Guidelines have been developed to minimize internal heating of TDA fills ( 2 ) as discussed in 6.11 . The guidelines are applicable to fills less than 3 m thick. Thus, this practice should be applied only to TDA fills less than 3 m thick.
