Data for: Influence of Dosage, Curing and Ash Production on the Cyclic Performance of Rice Husk Ash-Stabilized Pavement Subgrades

Description

This dataset accompanies the critical review "Influence of Dosage, Curing and Ash Production on the Cyclic Performance of Rice Husk Ash-Stabilized Pavement Subgrades." It corresponds to the data extracted from 98 primary studies, selected from 440 records systematically identified in Scopus following PRISMA guidelines (complemented by a targeted Google Scholar search), on the use of rice husk ash (RHA) for stabilization of pavement subgrade soils. For each study, the extracted variables include: optimum RHA dosage, activation mechanism (pozzolanic, cementitious, alkaline/geopolymer, or RHA alone), reported ash combustion temperature, curing age/duration, and type of cyclic or durability evidence (if any). The full extraction table (Table S1) is presented in the Supplementary Material submitted together with the manuscript

Steps to reproduce

Data were obtained through a systematic literature search in Scopus (title-abstract-keywords) following PRISMA guidelines, covering studies on rice husk ash (RHA) for soil and pavement subgrade stabilization. From 440 records initially identified, 98 studies were selected for detailed data extraction after screening by title/abstract and full text against predefined inclusion and exclusion criteria. For each selected study, data were manually extracted and classified for optimum RHA dosage, activation mechanism, ash combustion temperature, curing age/duration, and type of cyclic or durability evidence, as detailed in Table S1 of the Supplementary Material accompanying the manuscript.
