Abstract

This study describes the use of recycled concrete aggregate as an aggregate in rigid pavement. The objective of this study is to know the suitability of recycled aggregate as replacement material of normal 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, the result shows that, the recycled concrete has satisfied the requirement of concrete strength for grade 20 N/mm² at 28 days. However recycled concrete has achieved the maximum strength of 39 N/mm² at 28 days for concrete grade 40 N/mm². From the compression tests result, it is shows that, recycled aggregate has approach the limit of specification and can be used in concrete mixing for concrete pavement.
