摘要：

为了推进废旧轮胎在土木工程中的应用，选择废旧轮胎片体(tire derived aggregates, TDA)与分布广且价格低的风化料混合形成混合料，并用TDA在混合料中以0~60%的掺量，通过大尺寸击实设备开展重型击实试验，研究废旧轮胎片体-风化料混合物的压实特性。试验结果表明，混合料的击实曲线与纯风化料的击实曲线有明显差异，增加废旧轮胎片体的掺量能够有效减小混合料的最大干密度，能减小混合料的最优含水率，废旧轮胎片体-风化料混合物是一种性能优良的轻质填料。根据室内试验结果，TDA掺量为20%时，混合料的最大干密度和最优含水率分别为1.865 g/cm3和6.25%；TDA掺量为40%时，混合料的最大干密度和最优含水率分别为1.600 g/cm3和4.90%，给出了不同掺量混合料击实指标建议值供设计参考。

Abstract:

To promote the usage of scrap tires in civil engineering, the 0~60%content of tire derived aggregates by weight were mixed with widely distributed and low price weathered rock materials, and the compaction properties of tire derived aggregate-weathered rock material mixtures were studied based on heavy compaction tests performed by the large size compaction equipment. The experimental results showed that the compaction curves of mixtures were obviously different from that of pure weathered rock materials. As the content of tire derived aggregates increased, the maximum dry density of mixtures effectively decreased and the optimum water content of mixtures reduced. Tire derived aggregate-weathered rock material mixtures could be used as the lightweight backfill with good properties. According to the results of laboratory tests, the maximum dry density and optimum moisture content of mixtures were 1.865 g/cm3 and 6.25% when the TDA content was 20%, and the maximum dry density and the optimum moisture content of mixtures were 1.600 g/cm3 and 4.90% when the TDA content was 40%. Compaction parameters of mixtures could be proposed for design based on laboratory test results.

Key words: tire derived aggregates, weathered rock materials, compaction properties
