Caltrans Hosting Open House on Precast Concrete

The California Department of Transportation (Caltrans) is breaking new ground in the use of precast concrete and is inviting government agency personnel, academia and consultants to an open house, workshop aand plant tour to hear about and see demonstrations of this latest approach to precast concrete pavements. The event is being held in conjunction with the Federal Highway Administration and will take place June 15. Registration is limited to the first 60 respondents, so if you are interested it would be wise to sign up immediately.

The San Francisco Bay Region of Caltrans has embarked on a major pavement rehabilitation project using a combination of jointed precast (JPPCP) and precast prestressed concrete pavement (PPCP) to replace sections of an existing jointed concrete pavement that needed rehabilitation. The project is at I-680 near Oakland and is currently in construction and will near completion this summer.

The project features a number of differences from previous precast pavement projects, including the use of two-way pretensioning (longitudinal and transverse directions), elimination of stressing pockets, reduction in the number of post-tensioning ducts, and utilization of longer panels ranging from 18-36 feet in length.

The open house will start in the morning with a visit to the steel strand and precast facility and will continue with a workshop in the afternoon. It will conclude with a site visit. Pre-registration is required to attend any of the activities.
