Mechanical properties test of pavement base or subbase made of solid waste stabilized by acetylene sludge and fly ash

open access: yesAIP Advances, 2020
As a sustainable development requirement, rational utilization of solid waste has been paid more and more attention, such as acetylene sludge (AS), fly ash (FA), coal gangue, and construction waste used in civil engineering. The comprehensive utilization

On Covering Prosperities via Neutrosophic e‐Open Set in Neutrosophic Topological Space

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
This research presents and explores a novel category of compactness in neutrosophic topological spaces (NTSs), termed neutrosophic e‐compact and neutrosophic locally e‐compact. This category is positioned within the frameworks of neutrosophic δ‐semicompactness and neutrosophic δ‐precompactness, while also encompassing neutrosophic β‐compactness.

Intelligent Prediction of Pavement Structural Degradation Using a Multimodel Ensemble Learning Approach

open access: yesStructural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Accurate prediction of the long‐term structural response of pavement systems is critical for performance evaluation and intelligent maintenance within the context of structural health monitoring. This study proposes an automated machine learning framework to predict the time‐dependent evolution of pavement rutting and deflection using full‐scale ...

Three‐dimensional reconstruction of loose defects in semi‐rigid base layers using enhanced deep learning and point cloud from GPR images

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 31, Page 6475-6492, 29 December 2025.
Abstract Loose defects in semi‐rigid base layers can critically compromise the structural performance and long‐term serviceability of asphalt pavements. However, accurate identification and quantitative assessment of such defects remain challenging due to the lack of reliable ground‐penetrating radar (GPR) data sets and the limitations of existing ...

Stabilisation and bearing capacity improvement of granular platform [PDF]

open access: yesE3S Web of Conferences
Building roads or platforms on weak soil is a remaining challenge. The reduction of granular material required for the subbase is more and more crucial, for cost reasons but also for a much lower impact of the earthworks on the environment. Geosynthetics

Sustainable utilization of landfill mined soil like fraction in subbase layer for asphalt road applications

open access: yesCleaner Materials
The scarcity of natural resources, and energy demand/carbon footprints related to their processing and transportation, has led to the quest for alternate materials for road/pavement construction and other infrastructure development.

Subbase characterizations of compact topological spaces

open access: yesGeneral Topology and its Applications, 1979
Abstract In this paper we give characterizations of some classes of compact topological spaces, such as (products of) compact lattice, tree-like and orderable spaces, by means of the existence of a closed subbase of a special kind.

Dyadic Subbases and Representations of Topological Spaces

open access: yes, 2005
We explain topological properties of the embedding-based approach to computability on topological spaces. With this approach, he considered a special kind of embedding of a topological space into Plotkin's $T^\omega$, which is the set of infinite sequences of $T = \{0,1,\bot \}$. We show that such an embedding can also be characterized by a dyadic

Performance Evaluation of Cement-Stabilized Oil Shale Semicoke as Base or Subbase Course Construction Material

open access: yesAdvances in Materials Science and Engineering, 2018
Oil shale semicoke is a hazardous byproduct in oil shale retorting process. In Jilin province, China, abundant oil shale resources are mainly used for retorting shale oil accompanying with a large number of oil shale semicoke slags, which will generally ...
