Abstract

This paper present the suitability of ceramic waste aggregate (CWA) as partial replacement for coarse aggregate in asphaltic concrete. In order to achieve this consistency testssuch as sieve analysis, aggregate crushing and impact value, water absorption, particle shape (flakiness and elongation) and specific gravity were conducted for coarse aggregate and ceramic waste aggregate. Asphalt briquette,
using 100% conventional coarse aggregate (control) and variations of ceramic waste aggregate from 10%to 50%were prepared. From the test results, it was observed that the stability value of conventional coarse aggregate (control) gave 4kN and that of CWA of 50% and 20% gave 3.59kN and 4kN respectively as against 3.5kN as minimum value specified in Nigerian General Specification for
Roads and Bridges (NGSRB). The corresponding flow, voids in total mix and voids filled with bitumen for sample containing 0% CWA, the values are: 2.88mm, 4.2% and 71.93% respectively, samples containing 20% CWA had flow, voids in total mix and voids filled with bitumen values as 2.77mm, 4.8% and 73.93% respectively and the sample containing 50% CWA had flow, voids in total mix and voids filled with bitumen values as 2.58mm, 10.80% and 85.52% respectively.
