Alameda Project Exceeds Expectations

This article describes the Alameda Corridor, a 26-mile super-cargo highway that connects the ports of Los Angeles and Long Beach and the Intermodal Railway Yard in downtown Los Angeles. This section of highway accommodates 50 to 75% heavy trucks. The authors describe the three potential asphalt problems that were addressed in this project: rutting, fatigue cracking, and low temperature cracking. Superpave mix was chosen for a portion of the project because of its performance characteristics. Project design engineers specified 20 inches of Superpave mix of four inches of aggregate for the Superpave section (which comprised two-thirds of the project; Caltrans 3/4-inch mix was used on the other third). The authors describe the construction issues, compaction, the use of night work for paving operations, maintenance considerations, and performance in the first 5 years of the project. The authors conclude that the Superpave portion is performing well, with no rutting or deformation.
