Thermal Behaviors, Interfacial Microstructure and Molecular Orientation of Shape Memory Polyurethane/SiO<sub>2</sub> Based Sealant for Concrete Pavement

Expansion joint failure is one of the main causes that lead to the damages of concrete pavement. The silicon dioxide/shape memory polyurethane (SiO<sub>2</sub>/SMPU) is a new kind of sealant which can use its shape memory performance to adapt to the width of the expansion joint with the...
