Experimental Evaluation of Abrasion Resistance in Hydraulic Structures Using Recycled Cement-Asphalt Materials

Concrete production has grown significantly, initially driven by urban development, followed by advances in construction techniques and the widespread adoption of on-site manufacturing.This increased production has led to a substantial amount of concrete waste, with some regions reporting waste volumes equivalent to up to 80% of the original concrete produced.To address the environmental impact, sustainable approaches have been developed to reduce concrete waste through recycling.Extensive research has been conducted on the effects of various methods on the properties of concrete, including recycling and mixing it with other construction materials.This study focuses on small hydraulic structures constructed from recycled asphalt concrete.A mixture was formulated based on experimental and laboratory data to attain a strength of 30 MPa at 28 days of age.Samples of recycled asphalt concrete and conventional concrete, measuring 20205 mm, were produced to assess corrosion levels using the water jet method.The results indicated that the recycled asphalt concrete exhibited a lower corrosion rate than conventional concrete after both 7 and 28 days, particularly at water jet angles of 45 and 90.These findings suggest that hydraulic structures made from recycled asphalt concrete may have a longer service life due to enhanced corrosion resistance, contributing to more sustainable and environmentally responsible construction practices.
