Use of recycled concrete aggregate for pavement

01/01/2020· The use of recycled concrete aggregate (RCA) for the production of concrete is limited to low strength concrete due to the difficulty in quality control and poor strength. RCA is, therefore, primarily used in pavement base and subbase courses as a substitute to natural crushed rocks. Recycling of waste concrete in pavement construction not only decreases materials going into landfill, but also

The Use Of Recycled Concrete Aggregate As an Aggregate in

aggregate in rigid pavement. Recycled aggregate and normal aggregate are two different types of aggregate to be used in this study. There are several tests implemented in this study; Compressive Strength, Water Absorption, Los Angeles Abrasion Value and etc. The test are conducted by using several samples where it is used to test the strength of concrete at 7 days and 28 days. After the test

Potential of Natural and Recycled Concrete Aggregate

This study investigates the feasibility of using recycled concrete aggregate (RCA) as a partial substitution of natural aggregate in pavement engineering. Despite RCA’s good properties, such as polishing value and freeze-thaw resistance, its use is limited by low resistance to fragmentation and high-water absorption. This paper parent the experimental results of mineralogical-petrographic

Sustainability Assessment of Using Recycled Aggregates in

For a better understanding of the benefits of using recycled aggregates in a pavement sub-base, a comparison was performed against a specific virgin aggregate use (with elastic modulus 250 MPa, which is the most common value, Figure 11). Virgin aggregate is considered as the basis of comparison since it has no net benefits. In addition, social acceptance was considered to be consistent

Recycled Aggregate Concrete: Applications, Advantages

Recycled aggregate concrete (RAC) is produced in three major steps: Evaluation of Source concrete: The first step in production of RAC is to determine the quality of the source concrete. Properties and records of source concrete like strength, durability and composition are looked into for deciding the proper source concrete. Crushing of demolished concrete: The simple process involves
