ECO Polyurethane Pavement Type I
Scope of Applications
Steel and concrete bridges、Airport runways
Large-span, flexible-stiffness steel bridge decks in heavy-traffic areas
-
≥40MPaCompressive strength
-
≥25MPaFlexural strength
-
≥6MPaTensile strength
-
≥9MPaShear strength
-
(no cracking after 10 million cycles)Fatigue resistance
Features
Structural Composition:
Upper Layer: ECO Modified Polyurethane Waterproof Bonding Layer;
Lower Layer (in contact with steel deck): ECO Modified Polyurethane Mixture (binder + aggregates);
Advantages:Leverages superior mechanical properties to enhance deck stiffness, addressing traditional shortcomings such as;
Insufficient mechanical performance, low rigidity, poor high/low-temperature stability and typical distresses (rutting, water damage, fatigue cracking)
