China Harbor Engineering Company has been accepted by Sri Lanka Port Authority (SLPA) as the Design and Built Contractor. During the Conceptual Study Stage the specified pavement type for the container yard have no difference between the container pedestal and the area in-between the pedestals. However, the cost of the initial design exceeded the contractor's budget. To solve this problem, our design team is looking for the optimal pavement structure, which minimizes the cost while meeting all the engineering constraints. This paper describes the optimum design for the loaded container stack and RTG runway foundation. Traffic demand on truck and passing lanes was evaluated based on estimated throughput including the effects of container type, size, block size and dwell time. The design followed the 2007 Structural Design of Heavy duty pavements for ports and other industries (4th edition). Finite element modeling was used to determine design chart specified in the guideline. The final solution should further consider the construction cost, construction period, maintenance, Performance and Durability as well as operation management.

Introduction In 2011, the government of Sri Lanka (GOSL) has embarked on a $375.1-million expansion program at the Port of Colombo, Sri Lanka to cater to the increasing demand of services in the international shipping industry. The main features of the project, known as the "Colombo South Container Terminal Project," were the design and construction of a 1200m 1...
