I-10 Pavement Rehabilitation between I-5 and I-605

I-10 Pavement Rehabilitation improves 13 miles of the I-10 freeway, stretching between I-605 in Los Angeles and I-5 in Baldwin Park. The project involved the replacement of the existing asphalt in the HOV and auxiliary lanes, as well as the existing asphalt buffer lane and outside shoulders. Furthermore, 5,000 mainline panels were replaced to enhance the roadway's condition. Additionally, the rehabilitation covered 18 miles of shoulder lane pavement, necessitating new drainage, electrical, and communications systems. During the project, a series of long-term closures were executed, including 30-day and 42-day closures, leading to the reconstruction of 18 on/off-ramps and the replacement of existing barriers, along with bridge deck resurfacing. To mitigate disruptions on this heavily traveled roadway, construction activities were primarily conducted during nighttime hours and weekends. 

The successful execution of this project relied on the utilization of volumetric trucks, complemented by meticulous calibration and refined mix designs. The construction process was marked by expert sequencing and scheduling across the four stages of construction. Additionally, retrofitting the existing four-lane roadway bridge, which spanned the Metrolink right of way and both directions of I-10, involved the demolition and replacement of concrete barriers and bridge deck overhangs. This work necessitated railroad training and qualification to ensure safety and coordination with train schedules and shutdown periods. Adequate rail line protection was established by deploying engineered timber mats.
