Characteristics Of Recycled Concrete

Characteristics Of Recycled Concrete

Use of recycled concrete aggregates RCA as a pavement material is one of the most sustainable engineering applications for the pavement industry. Investigation on the performance characteristics of RCA such as elastic and plastic deformations of RCA is therefore needed to assess RCAs application as an unbound pavement material. In this study repeated load tri-axial RLT tests were . For every production challenge, there is a solution - when you have the right partner. Whether you run a large quarry or a construction contracting business, we take your business personally. We offer the highest dependability for the entire life of your business.
