Esolution Receives ministry of transportation Approval in Saudi Arabia

Esolution construction and Engineering receives ministry of transportation approval for design, supply and installation of posttension concrete work for bridges based on submitted documents for CE marked European Approved materials that are being used currently in bridges in Saudi Arabia.

Esolution submitted all test reports for multistrands anchorages being tested according to ETAG013 and superseded by EAD 160004-00-0301 and EAD 160027-00-0301, whereas the posttension kit are tested according to European standards and effectively succeeded into testing according to AASHTO specification for bridges

European Approvals have raised the bar to provide construction markets with higher capacity and more durable PT Systems. ETAG013 approval is given to select companies which can demonstrate that they possess the knowledge and experices of design, manufacture and installation of Pt systems

Approvals of a PT system under the ETAG013 Guidelines may only achibved by carrying out strignet load testing of the anchorage components included in the posttension system, having comprehensive quality management system in place to check the manufacturing process of all supplied components in their posttension system

Tests

  • Resistance to static load: Posttension system are able to develop a specified percentage of the tensile element ultimate strength with a minimum elongation, without premature failure of the anchorage
  • Resistance to Fatigue of the tensile element, anchorage, coupling assembly, PT systems shall be able to withstand specified fatigue loads ( dynamic strength) without exceeding a specified percentage loss of tensile element cross section
  • Load transfer to the structure ( mechanical and bond anchorages) : PT System shall be able to transfer a specified percentage of the tensile element ultimate strength from the anchorage into the concrete structure, of a defined concrete strength without undue cracking of the structure and at deformation which stabilize within a given time frame
