The primary objective of this report is to quantify the aggregate base properties required for concrete pavement foundations in accordance with currently established layer thickness requirements. The effects of properties of different base layers on concrete pavement performance were evaluated, based on an the mechanical and hydraulic
aggregate types, and air contents of the concrete. Various fresh and hardened concrete tests were conducted on each of the mixes, and the results were used to determine the influence of the structural fibers on the fresh and hardened concrete properties. The study recommended the allowable range of the SAM number and provided

Mechanical Properties Since aggregates make up a large volume of the concrete, the type of aggregate has a major impact on the mechanical properties of the concrete [3, 8, 9]. Aggregates largely control the stiffness and creep of a concrete mixture. However, these properties are more dependent on the aggregate type and volume

This research investigated the effects of incorporating recycled concrete aggregate (RCA) at low replacement levels on the properties of concrete. Four different RCA sources were used, each with different aggregate properties. For each source, replacement levels of 5, 10, and 15% were tested and compared to a control group, which had no RCA.
