Abstract (en)
[origin: EP2690218A2] The method involves carrying out crack analysis in concrete sleepers (6). A crack (1) in the concrete sleepers is dammed such that confinement is applied along the crack in a strip form. A clearance surface is formed in an upper area of the concrete sleepers by removing the confinement along the crack. A filling substance is injected into the clearance surface on the crack by using an injection device and a low pressure pump until the crack is completely filled by the filling substance, so that the low-pressure pump is controlled by using a pressure drop sensor. The filling material is one-component, two-component or multi-component epoxy resin or polyurethane.
