Abstract

Abstract: This paper presents the possibilities of reusing recycled materials in road pavement constructions. Waste materials came from old and damaged pavement layers. The reclaimed asphalt pavement (RAP) was used to create new layers of road surfaces - the base layers. The base layers were made of mineral-cement-emulsion mixtures (MCE). The main issue was to assess the impact of the RAP in MCE mixes on the physical, mechanical and rheological properties of the recycled base layer. The use of reclaimed asphalt in MCE mixes reduces road construction costs and allows for the ecological coexistence of the investment with the environment. The research results were developed as part of the project entitled "The innovative technology used the binding agent optimization that provides the long service life of the recycled base layer" (TECHMATSTRATEG1/349326/9/NCBR/2017) within the scientific undertaking of Strategic Research and Development Program entitled "Modern Materials Technology" (TECHMATSTRATEG I), which is financed by the National Center for Research and Development (Polish NCBiR). Keywords: MCE mixture; Road pavement recycling; Reclaimed asphalt pavement (RAP); Cement dusty by-products

再生沥青在再生路面中的应用

摘要：本文介绍了再生材料在道路路面施工中再利用的可能性。废弃材料来自旧的和损坏的路面层。再生沥青路面（RAP）用于创建新的路面层——基层。基层由矿物水泥乳液混合物（MCE）制成。主要问题是评估MCE混合物中RAP对再生基层的物理、机械和流变性能的影响。在MCE混合料中使用再生沥青降低了道路建设成本，并允许投资与环境的生态共存。该研究成果是在题为“现代材料技术”的战略研究与发展计划（技术战略I）的科学事业范围内，作为题为“使用粘合剂优化的创新技术，可延长再生基层的使用寿命”的项目（技术战略1/3349326/9/NCBR/2017）的一部分而开发的，该项目由国家研究与发展中心资助。关键词：MCE混合物；路面回收；再生沥青路面（RAP）；水泥粉尘副产品
