COMPARISON OF STRUCTURAL DESIGN PROCEDURES OF RCC PAVEMENTS DUE TO HEAVY LOADED APRONS (CONTAINER TERMINALS)

Roller-compacted concrete (RCC) or cement bound granular mixtures (CBGM or CBM) is an ultra-tough, zero-slump concrete pavements. It is placed with asphalt pavers to form a nonreinforced, concrete pavement. RCC successfully and economically combines strength and durability with ease of construction especially in heavyduty industrial pavements (e.g. ports and multimodal terminals). Ports and heavy industrial facilities are large, open areas with few obstructions that may delay the construction process, making them ideal candidates for RCC. Pavements for port and other heavy industrial facilities must be strong and durable because container handling equipment can have wheel loads of 14 to 28 tonsor more per tire with traffic speeds typically less than 48 km/hr which are uncommon. The selection of the pavement course materials and thicknesses is a major part of the pavement design process There are already several manuals providing guidance on this aspect of container terminal pavement design such as BPA, OCDI, USACE and RCC-PAVE computer program that are the most common pavement design methods used for this application [1-7]. This paper compares the pavements designed by each manual in view of technicaland construction procedures and reveals the differences in each procedure.
