Evaluación de la degradación por compactación de materiales granulares tipo subbase

Revista EIA, 2019
Los materiales granulares de subbase y base empleados en estructuras de pavimento son susceptibles a degradarse debido a múltiples factores inherentes a los procesos de producción, construcción y operación vial. El objetivo del presente artículo es cuantificar la degradación de materiales granulares por la incidencia de la recompactación, empleando ...

Development of Geocapillary Barrier System for Water Retention in Highway Landscaping

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
This study investigates the potential use of geosynthetic materials as capillary barriers to enhance water retention in landscaping soils. The soil was first classified using the Unified Soil Classification System (USCS); then, the Van Genuchten model was used to model and compare the unsaturated hydraulic characteristics of the soil and geosynthetic ...

Strength Improvement of Black Cotton Soil With Cement and Waste Glass Powder for Subgrade Stabilization

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Expansive soils cause volume changes because they swell and lose strength when wet and shrink when dried. Light buildings and pavements constructed over such soils will not last long due to settlement and cyclic volume changes. Therefore, the purpose of this study was to blend black cotton soil with cement and waste glass powder (WGP) in order to ...

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.
