Prediction of compressive strength based on durability parameters of roller-compacted concrete using recycled pavement materials
Year: 2026
Type: article
Abstract: This study examines the mechanical and durability performance of roller-compacted concrete pavement (RCCP) incorporating recycled asphalt pavement (RAP) as a partial or full replacement of natural aggregates (NA) (0–100%). The replacement levels considered were 0%, 25%, 50%, 75%, and 100%. Concrete specimens were exposed to acidic and sulfate solutions (1% HCl, 3% H2SO4, 5% Na2SO4, and 5% MgSO4) to simulate long-term environmental stress. Results showed RAP enhanced resistance to chemical attacks up to 50% substitution, while higher contents reduced compressive strength (CS) but maintained acceptable durability. An empirical model predicting CS as a function of exposure type and curing time showed a strong correlation with test results. This research confirms RAP as a sustainable alternative to natural aggregates, supporting resource conservation, waste reduction, and cost efficiency in pavement construction.
