Study on Interlayer Performance of Polyurethane Concrete Steel Bridge Deck Pavement
The mechanical properties and microstructure of polyurethane concrete were studied by experiments.The results showed that polyurethane concrete could form a strong bonding force with steel bridge deck,and the interlayer bonding strength was higher than the tensile strength of polyurethane concrete.The tensile strength of polyurethane concrete at 60℃ was less than 50%of that at 25℃ and less than 30%of that at-30℃.The failure form of the specimen was compressive failure when the compressive shear angle was 15°.When the shear angle was 45°,the failure mode of the specimen was shear failure,and the composite structure had good anti-fatigue cracking ability.This study provided an important reference for the design and application of polyurethane concrete steel bridge deck pavement.
