I-10 | El Monte, California

Precast prestressed concrete pavement was used on a section of I-10 near El Monte, California as a part of widening the interstate. 27 feet of traffic lanes and 10 feet of shoulder were added to the existing pavement. Construction was limited to the hours of 11 pm – 5 am for installation of the panels.

A change in cross-slope was required from the mainlanes to the shoulder. This was accomplished by casting panels with a flat bottom and variable thickness to achieve the desired cross slope transition. The panels were installed over a lean concrete base. Plain dowelled expansion joints were used for the joint panels and central stressing was utilized for longitudinal post-tensioning.
