Low‐Carbon Recycling of Engineering Muck Through Phosphogypsum: Modeling, Optimization, and Durability Performance Investigation

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
With the rapid development of urban infrastructure in China, engineering muck has emerged as a potential urban risk. The improper disposal of engineering muck not only results in the inefficient occupation of land resources but also poses serious threats to ecological systems and geotechnical stability.

Evaluation of the Performance of a Composite Material Made From Lateritic Soil, Crushed Granite, and Cement for Use as the Base Layer of Road Pavement

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
The base layer is important for the road pavement structural performance. This study aims to monitor the performance of various local composite materials as road construction materials. To do this, an experimental study treated the improvement of geotechnical properties of a lateritic gravel, initially nonadopted as a base layer, by using three ...
