Abstract: With the development of deep learning and information technologies, intelligent welding systems have been further developed, which achieve satisfactory identification of defective welds. However, the lack of labeled samples ...

Abstract: Recent years have seen a growing trend of Chinese companies making significant inroads into the international construction market. However, comparing to their fast development, only few studies have been reported to introduce ...

Abstract: A generic crack bridging model for short fiber-reinforced cementitious composites is developed aiming to analytically account for fiber tensile rupture at the pullout stage and two-way fiber pullout induced by both the ...

Abstract: Polyurethane (PU) asphalt binders have been proved to be a promising class of paving materials for steel bridge deck or highway road. This study further evaluated the performance of a thermosetting-PU (TS-PU) asphalt mixture ...

Abstract: Polyurethane (PU) is a synthetic material available for researchers to be designed in terms of their demands. This study prepared a novel polyurethane thermoplastic elastomer (PUTE) as an asphalt modifier through the ...

Abstract: This study investigated the modification mechanism of polyurethane (PU) on the high- and low-temperature properties of asphalt based on experimental and molecular dynamics (MD) simulations. PU-modified asphalt was prepared ...

Abstract: Considering the defects of insufficient low-temperature flexibility and high cost of epoxy asphalt binder, low-cost polypropylene glycol (PPG) and toluene diisocyanate (TDI) were used to synthesize two polyurethane (PU) ...

Abstract: This paper presents the experimental and numerical investigations of two types of bonded posttensioned concrete bridge beams under hydrocarbon fire, including the box and tee beams. The factors considered included the load ...
