Design a No-Fine Concrete Using Epoxy in Pavement

No-fines concrete is an advanced pavement material known for its strong drainage capabilities, making it a widely used rigid road surface. With growing demand for reduced cement content due to industrial advancements, researchers have explored epoxy resin as a partial or total cement replacement. This study examines the mechanical properties of no-fines concrete with varying epoxy replacement levels and applies KENSLAB analysis for pavement thickness design. Seven concrete mixes were prepared with epoxy replacing cement at ۱۰۰%, ۹۵%, ۷۵%, ۵۵%, ۳۵%, and ۱۵%. Mechanical tests, including compressive strength, flexural strength, modulus of elasticity, bulk density, water absorption, and durability (wet-dry), were conducted after ۷ and ۲۸ days of curing. Additionally, the PerviousPave system was used to optimize pavement integrity by adjusting slab thickness, subbase layer thickness, and stormwater management. Results showed that the ۵۵% and ۱۰۰% epoxy replacement mixes performed best. Compressive strength increased by ۲.۴۴% and ۳۳.۴۴%, respectively, at ۲۸ days compared to the reference mix. Flexural strength reached ۵.۹۹ MPa for ۱۰۰% epoxy and ۴.۶۹ MPa for ۵۵% epoxy at ۲۸ days. Structural analysis demonstrated that increased slab and subgrade stiffness reduced tensile stresses, improving pavement durability and extending service life. These findings highlight the potential of epoxy-modified no-fines concrete for enhanced pavement performance in traffic and environmental conditions. Doi: ۱۰.۲۸۹۹۱/CEJ-۲۰۲۵-۰۱۱-۰۵-۰۲۱ Full Text: PDF
