Repairs with high-performance concrete
Modeling and computational verification of efficacy
To eliminate deformation damage, e.g.thin (TWT: 10-20 cm) or ultra-thin (UTW: 5-10 cm) concrete cover layers (whitetopping) can be built on old asphalt and concrete tracks. High-performance concrete (HPC) or ultra-high-performance concrete (UHPC) is used for the realization of ultra-thin surfaces. Such concretes have long been successfully used in constructional engineering where extreme compressive strengths and lean structures are required.
