Description

[0002] With the acceleration of urbanization and growing transportation demands, highway widening projects have become a crucial component of urban transportation development. However, highway widening presents numerous challenges, particularly in soft soil and complex terrain. Traditional embankment filling materials and technologies often fail to meet deadlines, quality, and environmental requirements. Therefore, exploring new embankment filling materials and technologies is crucial for improving the efficiency and quality of highway widening projects.

[0003] Furthermore, foamed concrete, a new lightweight filling material, has been widely used in highway widening projects due to its lightweight, high-strength, thermal and sound insulation, and environmentally friendly properties. Foamed concrete contains a large number of independently closed colloidal bubbles, which allows its construction density to be kept low, effectively reducing the bearing pressure on the foundation. Furthermore, foamed concrete exhibits high fluidity, self-supporting properties, and low elasticity and shock absorption, which contribute to the stability and safety of embankments. However, in practical applications, foamed concrete still suffers from issues such as easy settlement and difficulty in anchoring to existing structures.
