Low-Carbon Emission Demolition of an Existing Urban Bridge
Carbon emission is an important index to evaluate the green degree. To quantify carbon emissions, Life Cycle Assessment (LCA) is a widely used method. It divides the cycle into six stages: raw material acquisition, material processing, component production, construction, building operation and maintenance, and demolition. Especially for the bridge demolition stage, a decisive factor in the carbon emission quantity is the demolition method. A demolition scheme of "Self-propelled modular transporter (SPMT) technology + large segment cutting" is proposed with low carbon emission, high efficiency and safety.

Imaging Techniques for Bonding Zones of Asphalt Layers
The material behavior of asphalt depends on its composition of aggregate, bitumen, and air voids. Asphalt pavements consist of multiple layers, making the interaction of the materials at the layer boundary important so that any stresses that occur can be relieved. Image analysis is a widely used technique in materials science that allows to analyze the material behavior and their composition. With high-resolution computed tomography, a detailed view is possible to visualize the individual materials at the layer boundary in 3D.

Ultra-High-Performance Concrete (UHPC) Piles and Splicing Options
Conventional driven piles are made from steel, concrete, timber, or composite materials. These piling options have limitations with respect to corrosion, durability, driveablity, and performance. Ultra-High-Performance Concrete (UHPC) pile is a new alternative that has already been adopted by various state Departments of Transportation in the United States for addressing the limitations that exist with conventional piles. UHPC piles are made of a cementitious composite material mixture that possesses exceptional properties such as higher strength, low capillary porosity, and high resistance to corrosion, making them a suitable option for use as a deep foundation. For several reasons, it is necessary to cast piles with a shorter length and splice them at the site to reach the desired lengths.
