BR-040 HIGHWAY – BELO HORIZONTE (MG)

CHALLENGE The DNIT inspection detected marked erosion at the base of construction and crushing of the structural bearings, and recommended immediate replacement; a risk of collapse was evident. The very poor condition of the pavement placed the safety of the users at risk.
SOLUTION It was essential to ensure the safety of the users during the works, with the least impact on traffic. The first step was to contain erosion with an anchored retaining wall. The work included the installation of an efficient drainage system, block and pillar recuperation and replacement of the bearings with hydraulic jacks for the 115m span, and new paving. Everything was executed without interrupting traffic.
