With the increased knowledge of sustainable pavement construction, recycled materials more and more are being used in roadwork applications, especially as base materials. Among various recycled materials, recycled glass aggregate is of the special attraction in the present study. The main goal of this investigation is evaluating the behavior of base course containing recycled glass using resilient modulus (Mr) from laboratory testing. In this regard, recycled glass (RG) is replaced the same range size of the local base course material (MG20) based on volumetric method. The studied RG aggregate was in the range size of 0-5 mm. The results revealed that as RG content increased, Mr values of blends decreased. Furthermore, the shear strength of blends followed the similar trend as it decreases by RG contents. Finally, based on the experimental observation a model was proposed to interpret the effects of RG on the resilient modulus values of blends. Conclusively, using RG up to 25% of MG20 may change the growing trend of environmental problems, in a green way, without significant effects on the mechanical behavior. [ABSTRACT FROM AUTHOR] |
