Port of Long Beach, Pier C, Berth 60 Pavement Evaluation Services
PROJECT BACKGROUND
As the Port of Long Beach continues to become the nation’s top busiest container port, Pier C Berth 60 Terminal C60 is a Matson Navigation-dedicated facility providing services to the Hawaiian Islands, Guam and three ports in China – Ningbo, Shanghai, and Xiamen. SS Marine handles approximately 104 vessel calls per year for Mason Navigation.

PROJECT SCOPE
G3 Quality’s pavement engineers were requested to perform a pavement materials and geotechnical investigation for evaluating the cause of major pavement surface rutting observed primarily in the north east-west loading lane of the top-pick (TP) storage area at SSA Terminal C60. G3 Quality was contracted to perform a forensic pavement evaluation to determine the cause of rutting in the least heavily used container storage lane as compared to minimal pavement rutting in the container loading lane that was most heavily used. Two prior investigations were performed by others without conclusive findings as to causation nor recommendations for remedial steps.
OUR ROLE
Based on the review of the previous reports and discussions with the client’s representatives, G3 Quality focused on gaining a better understanding of the past conditions to develop the most appropriate investigation scope. This consisted of Heavy Weight Deflectometer (HWD) testing to relate pavement structural strength differences between the various areas. Cone Penetration Tests (CPTs) were utilized to evaluate deeper supporting soil strength at select locations. Shallow test pits were also excavated through the pavement structural section to locate the specific material rutting that was either confined to the asphalt concrete surface material, cement-treated base material, and / or the underlying supporting soil.
OUR ADDED VALUE
G3 Quality reviewed and analyzed all collected field and prior reported data and presented a thorough report and formal presentation to the client, including a description of the project and purpose of the evaluation; detailed description of the technologies, test procedures and testing conducted to evaluate pavement, cement treated base layer and underlying subgrade soils; summary of data; probable cause of pavement failure; and reconstruction recommendations. Through our investigation and conclusive cause of pavement failure, our client was able to move forward with a long-term remediation plan to restore the facility to a 25-year pavement life.
