LOAD TRANSFER RESTORATION AT JOINTS. PROCEEDINGS, 4TH INTERNATIONAL CONFERENCE ON CONCRETE PAVEMENT DESIGN AND REHABILITATION, PURDUE UNIVERSITY, APRIL 18-20, 1989

For several years, French engineers have been developing devices for load transfer restoration at joints to reduce pavement pumping. This paper describes the repair system which consists of metal connectors. The connectors are in the form of steel cylinders in two half-shells linked together by a steel pin sliding in a horizontal plane. The connectors are sealed by gluing in holes drilled vertically astride the joint between slabs. Special equipment is being developed for a rapid restoration to reduce traffic interruption and repair costs. Measurements carried out in situ show that the connector carries loads from one slab to the other efficiently and with an excellent resistance to fatigue and corrosion. The relative displacement between the two adjacent slabs is substantially reduced, and pumping effects are stopped. With the equipment being developed it is expected that one kilometer of one lane of a highway will be repaired in a day.
