冷再生混合料力学性能试验研究

在对冷再生混合料的配比和力学性能(抗压强度、抗压回弹模量和劈裂强度)室内试验的基础上，探讨了冷再生混合料力学性能的变化规律以及其影响因素．结果表明：旧的沥青混合料中掺入一定量的添加剂和适量的水之后，其物理化学性质得到了改善，抗压强度和劈裂强度有明显提高；再生混合料的力学性能主要取决于添加剂的种类、剂量和集料的级配．研究结果为有效控制和检验冷再生技术的实际应用提供了依据．

Experimental Study of Mechanical Properties of Cold In-place Recycling Mixture

A series of indoor experiments have been done to study compressive strength, compression modulus of resilience and cleavage strength. The experiments results are: 1) The old recycled asphalt mixture property will be improved when mixed with additive and proper water; 2) The compressive strength, compression modulus of resilience and cleavage strength will be improved; 3) The cold recycling in-place mixture property will be depened on what type of additive, how many of it and what type of aggregate gradation. The result can be used for checking and controlling the effect of repairing asphalt pavement with cold in-place recycling method.
