recycled aggregates are technically viable to build granular pavement layers (sub-base and base) from low traffic flow, in spite of the variability of the CBR results to recycled aggregates and flakes PET mixtures. The NBR 15115/04 standard [10] provides the use of recycled concrete aggregates for base and sub-base of low-traffic volume roads.

Environmental Suitability of Recycled Concrete Aggregates ...

A battery of laboratory geotechnical tests was conducted on graded aggregate base (GAB) course material, recycled concrete aggregates (RCAs) as well as mixtures of GAB-RCA to determine the mechanical performance of these materials. California bearing ratio (CBR), resilient modulus, and permanent deformation tests were conducted to investigate the

Jun 01, 2011  Research highlights 16,000 tons of solid wastes from civil construction are produced daily in São Paulo. Lab tests show similar behavior of RCDW aggregate and a standard granular material. Proper compaction energy increases the breakage of RCDW aggregate and its resistance. Permanent deformation is one of the main problems of the RCDW aggregate. RCDW aggregate may be utilized

Apr 18, 2019  Recycled Concrete Aggregate (RCA) is considered to be a potential substitute for natural aggregates in asphalt mixtures. Despite some contradictory results achieved by researchers, it is believed that RCA treatment can improve quality of recycled asphalt mixes considerably. In this research, a two-stage treatment was applied on coarse RCA materials in order to improve their

Recycled Concrete Road Base Compaction - Soil testing ...

Dec 05, 2006  For materials contain cement, it is important to take the density test immediately after compaction. When taken later after some hydration has occurred, the density values tend to go down. I've seen this in soil-cement, crushed recycled concrete, and cement-treated base materials. This is particularly true when a nuclear density gage is used.
