Comparing the mechanical properties of cold recycled mixture containing coal waste additive and ordinary Portland cement

摘要: Pavement cold recycling is considered as an efficient rehabilitation method, especially in severely distressed roads. Modifier additives have been used for improving the performance of recycled mixture (CRM), at initial days curing. In this study, coal waste taken from washing plant and its ash produced through incineration process were pozzolanic CRM with bitumen emulsion. To assess effects using these on mechanical properties CRM, Marshall stability, indirect tensile strength (ITS), resilient modulus, dynamic creep fatigue tests applied. Furthermore, effect moisture sensitivity was evaluated. Application powder improved but it could not exert a positive sensitivity. Thus, can be additive conditions that damage does significantly affect pavement performance. Unlike ...
