Project completed in Jul 2021 using ceEntek's ce200SF-G UHPC
The I-90 over Fuller Road project was a rehabilitation of an existing bridge. The steel girders in the previous bridge were susceptible to water leaking off the bridge deck, which caused major deterioration. The new design will prevent the corrosion of steel beams and girders.
Casting was scheduled for four weekends in June, and the bridge was split up into four different sections of 2-lanes that were replaced each weekend. Traffic was open on three sections while work was being done on the fourth. High early strength was necessary to open the bridge to traffic in less than 24 hours after the placement of UHPC. Accelerated strength gain to 10,000 psi (~70 MPa) of ceEntek’s UHPC 2.0 allowed stripping of formwork 8-10 hours after placement.
The new structure was Precast Modular Units (PMU) with UHPC closure pours and UHPC link slabs using ceEntek’s ce200SF-G. The deck was grounded and grooved leaving a smooth surface and UHPC exposed.
