Road Film Complex Type Bridge-decks Pavement Surface Waterproof

Conctruction Method Overview

It is complex type waterproof construction method to form waterproof layer with coating of road film waterproof material which is manufactured with high molecular forming asphalt and melted using heated melting method, and to install aramid grid which is protecting material for waterproof layer. It has excellent suppression ability for crack and is a new construction mathod of bridge waterproof to enhance durability of pavement

Construction Method Characteristic

- It has an excellent waterprrof ability and does not occur slip phenomenon by high tension and shearing adhesivity.
- It is able to construct irrelevant to concrete strengh and has crack suppression effect by aramid grid.
- It is able to continuous construction without joint portion and install irrelevant to floor shape (Concavo-Convex)
- It has an excellent adhesion with asphalt and is able to unify with waterproof layer, secures long term public service.
- There is no worry of waterproof crush by equipments (Finisher, Dump, etc) in case of ascon deposition.
- - Corrosion does not occur due to chemical durability.

Problem of Conventional Bridge-decks Surface Waterproof

When rain water is percolated into crack of concrete upper plate. crack is expanded gradually by freezing expansion, it generates corrossion of steel bar ans cracl of concrete.
