Performance Evaluation of Soil, Fly Ash, and Recycled Concrete Aggregate Geopolymer Mixtures for Pavement Base and Subbase Applications

In regions where suitable natural aggregates are scarce or expensive, soils are often treated with cement to produce pavement base and subbase materials. This study evaluated soil–RCA geopolymer mixtures as a sustainable alternative for these applications. Response surface methodology (RSM) was used to prepare mixtures...
