Abstract:

Four transverse joint designs for prestressed concrete pavements are presented. Items considered in developing the designs include slab length, tendon force, tendon size, tendon spacing, desired midslab prestress, allowable joint movement, and use of one or two active joints between adjacent main slabs. Proper attention must be given to joint hardware design because a large number of items such as anchors, strands, load-transfer devices, infiltration-prevention devices, reinforcement, and positioning bars are located within a few inches of the joint. Therefore, detailing of joint hardware is a critical element of design. Designs I, II, and III are for an 8-in-thick pavement with main slab lengths of 350 ft. A short prestressed gap slab and a single active joint are used between the main slabs. Design IV is for a 7-in-thick pavement with main slab lengths of 250 ft. A tied concrete shoulder is used. Gap slabs are 10 in. thick, conventionally reinforced, with an active joint at each end. (Author)
