Geotechnical Behavior and Microstructural Analysis of Expansive Subgrade Soils Stabilized With Coffee Husk Ash

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
This study examines the enhancement of engineering properties in expansive subgrade soils through stabilization with coffee husk ash (CHA), an agricultural byproduct obtained from coffee husk combustion. CHA was incorporated at 5%, 10%, 15%, 20%, and 25% by dry soil weight, and the soil–CHA mixtures were cured for 7, 14, and 28 days.

Mechanical and Microstructural Properties of Clay Tile Waste Concrete Treated With Silica Fume

Advances in Materials Science and Engineering, Volume 2025, Issue 1, 2025.
The increasing generation of Ceramic Clay Tile Waste (CCTW) has prompted the construction industry to explore sustainable alternatives in concrete production. This study investigates the use of CCTW aggregates as a partial replacement for natural coarse aggregates in concrete and silica fume (SF) as a pozzolana, addressing sustainability challenges in ...

Predicting Resilient Modulus of Fine‐Grained Soils Using Support Vector Machine‐RBF and Random Forest

Advances in Materials Science and Engineering, Volume 2025, Issue 1, 2025.
The resilient modulus (Mr) of subgrade soils is an important element in road pavement structural design procedures. However, because of regional differences in soil parameters and the nature of test procedures, determining Mr in the laboratory has become cumbersome.

Field Sampling and Laboratory Preparation of Hot Mix Asphalt (HMA) With Admixture: Insights From Erbil Roads

Journal of Engineering, Volume 2025, Issue 1, 2025.
Asphalt cement, often referred to as asphalt or bitumen, is a fundamental material used in the production of hot mix asphalt (HMA) for road pavements. Historically, asphalt was combined directly with other materials to create conventional HMA without any form of modification.

Applications of δ‐Open Sets via Separation Axioms, Covering Properties, and Rough Set Models

Journal of Mathematics, Volume 2025, Issue 1, 2025.
In this article, we make use of δ‐open sets to establish some topological concepts related to separation axioms and covering properties and to propose novel topological rough set models. We first demonstrate that the classes of regular‐open and δ‐open subsets of a finite topological space are equivalent when this space has the property of ∂(A)∩∂(B)⊆∂(A
