<p>This case study aims to investigate the effects of compaction methods on the mechanical behavior of roller compacted concrete pavement (RCCP) mixtures, which consist of the replacement of different cement by 0%, 5%, and 10% limestone by volume fraction and which were compacted by two compaction methods. These methods are commonly discussed in the literature and were developed to simulate the site conditions in the laboratory. A modified Proctor test was adopted in the mix’s proportional process to optimize the aggregate’s percentage content of RCCP. The experimental series consisted of compression and split tensile performance tests to investigate the development of compaction performances at 28 days. The results showed that, where 10% of the cement was substituted by limestone, the RCC gives important flexural strength values compared to the quantity of the cement substitute. Qualitatively, the reduction in the strength of the concrete using the modified Proctor compaction method led to the weakness of the bond between the layers.</p>
