Morelia-Lazaro Cardenas highway
Project description
The highway connecting the cities of Morelia and Lázaro Cárdenas in Michoacán state in southern Mexico was subjected to significant maintenance works in 2013 – 2014, with many bridge structures along its length being renovated. A number of the bridges required new expansion joints at each end of their decks, to provide a suitable driving surface for traffic while protecting the deck ends and preventing the passage of water through the deck’s movement gap.
mageba scope
mageba supplied 70 expansion joints for a large number of bridge structures on the highway: 36 TENSA-GRIP Type RS-B single gap joints (accommodating 110 mm of movement) and 34 TENSA-RSFD cantilever finger joints (allowing 160 mm of movement). The cantilever finger joints, in addition to facilitating greater movements, also minimize noise from traffic crossing the movement gap by providing continuous support to a vehicle’s wheels and thus avoiding the impacts that can result in noise.
