A 36-foot-long precast/prestressed concrete pavement (PPCP) panel is installed on the I-680 project in California. Caltrans used the panels for spot reconstruction of northbound and southbound lanes
In Delaware, contractors worked overnight to reconstruct Route 896 with precast/prestressed concrete panels. Each night, they removed existing 12-inch concrete pavement, placed a 4-inch pervious concrete base, installed 8-inch precast panels, and post-tensioned them together so the road could be opened to traffic the next day.
Precast/prestressed concrete pavement (PPCP) panels were used to reconstruct a section of Interstate 66 in Northern Virginia that carries more than 180,000 vehicles a day. Construction was limited to 9 p.m. to 5 a.m. each night to keep the road open to daytime traffic.
I-680 in California is open to traffic after precast/prestressed concrete pavement (PPCP) panels were installed the previous night.
Jointed precast pavement systems (JPPS) panels are interconnected similarly to cast-in-place pavement using dowels. The panels are typically heavily reinforced or pretensioned.
