Rigid pavement structures are one of the costly components of the infrastructure development process. It consumes a huge quantity of ingredients necessary for concrete development. Hence, a newly introduced concept of circular economy in combination with waste management was introduced to solve this problem. In this study, three waste products (rice husk ash (RHA), wood sawdust (WSD), and processes waste tea (PWT)) was utilized to develop the concrete for rigid pavement structures by replacing the sand, i.e., a filler material at different percentages. During the testing procedure of compressive (CS), tensile (TS), and flexural strength (FS) properties, RHA and WSD at 5% replacement were found to be a good replacement of sand to develop required concrete. This study will help in the production of eco-friendly rigid pavement structures and a pathway of life cycle assessment in the future.

路面绿色混凝土的性能评估：生命周期评估前提前决策方法的应用

刚性路面结构是基础设施开发过程中昂贵的组成部分之一。它消耗了大量混凝土开发所需的成分。因此，引入了新引入的循环经济与废物管理相结合的概念来解决该问题。在这项研究中，利用三种废品（稻壳灰（RHA），木屑（WSD）和加工废茶（PWT））通过替换沙子（即，一种填充材料）来开发用于刚性路面结构的混凝土。不同的百分比。在抗压（CS），拉伸（TS）和抗弯强度（FS）特性的测试过程中，发现以5％的比例代替RHA和WSD可很好地替代沙子，从而开发出所需的混凝土。
