| What is Thin Layer Overlay |
Thin layer overlay is a rehabilitation method of concrete pavements which are damaged only at the part of surface due to raveling and stripping, by laying and binding new concrete on existing pavements thus rehabilitating the function. Typically, overlays are done after milling surface part (about 5 cm). |  | |
For securing the binding of new and old concrete, shot blast treating is done. Treating by Hydro Milling which we are proud of, more strength of binding is secured.
In cases a few concrete slabs are damaged structurally or the under base course parts are damaged, partial reconstruction or Asphalt Injection Method which we WatanabeSato are proud of, are applied beforehand.  | |
