Construction of the first Malaysia’s hybrid concrete pavement using jointed plain concrete pavement (JPCP) and roller compacted concrete (RCC)

Abstract

Lafarge Infrastructure Team had constructed Malaysia’s first hybrid concrete pavement using Jointed Plain Concrete Pavement (JPCP) and Roller Compacted Concrete (RCC) at Lafarge’s Kanthan Cement Plant, Ipoh, Malaysia. The main purpose of the project is to showcase and study construction challenges in combining JPCP and RCC hybrid product for road solutions. The progress and pavement performance were monitored recorded and detailed through tests and site observation reports. JPCP pavement was constructed using two (2) type of construction methods; slip form and fixed form, while RCC pavement was laid and constructed using an asphalt paver set. The Quality Assurance & Control (QA/QC) monitored comprises of concrete design mix, concrete slump, concrete delivery, joints insertion, concrete curing, compaction, profile levels, saw cut and sequence of construction activities. Throughout the study, we have managed to table out the “Challenges and Best Practices” on the construction methods which mainly involves labours, machinery and material. All the information has been taken into consideration, to prepare a comprehensive report for the project. The study will enhance the knowledge and understanding for road owners, concrete suppliers, consultants and contractors in understanding the right application of JPCP and RCC in the future. We able to share and propose few best practices based on the challenges that we had face.
