The structure lifetime depends on preservation of the physical integrity of gross structure element. Therefore, an adequate inspection, maintenance and repair procedure for the entire structure are indispensable. The existing road structures have various damage patterns. The integrated evaluation process of damage based on the damage inspection result of various patterns is very complex.The research results are next items.1.Surveying system of damage factors effected structure lifetime was complete.2.Spectral analysis system of working stress of damaged structural elements based on Traffic Load Auto Measuring data system was assembled.3.Statical and dynamical motion simulation system of renewal structures consist of repaired elements and parts of road structures, reinforced concrete, steel and composited strucures was completed.By above results, Caring System of Damaged Structures was more useful.
