The AccelPG system is developed for post-tensioned concrete girders. The girder PT pulls double duty, using the horizontal component to compress the deck while reserving the vertical component of the PT to increase the girder capacity. AccelPG can result in up to 33% savings in girder lines required, comparing with the typical internal deck PT with prestressing girder solution.
AccelPG was developed for use with multi-span precast concrete girder bridges.
