These tests have shown that the current FAA rigid pavement design procedure has difficulty in predicting performance when corner breaks occur. This limitation stems from the fact that the FAA design procedure involves the computation of stress at the bottom of the Portland Cement Concrete (PCC) layer, whereas corner breaks initiate from the top. Further research highlighted the complexity of stress distribution on the PCC surface, where the critical stress location does not align with the gear loading point. This discrepancy underscored the need for a revised design approach to address corner breaks. So, in this study, researchers proposed a rigid pavement design framework that integrates a new corner break design procedure with the existing FAA procedure. The new corner break design procedure leverages machine learning for mechanistic analysis and fatigue modeling to assess damage. A novel approach was developed to calculate damage along joint “nodes” (intersections of longitudinal and transverse joints). Additionally, the concept of the pass-to-coverage ratio was removed for corner break design, and a new statistical procedure was introduced to allocate departures to distinct pavement locations. This enhanced framework was then combined with a modified version of the existing FAA design procedure. Parametric analyses demonstrated that the updated approach could potentially reduce PCC thickness by up to 1.5 inches for large-hub airports, offering a more efficient and reliable design solution.</div></div>","PeriodicalId":101261,"journal":{"name":"Transportation Research Procedia","volume":"99 ","pages":"Pages 362-369"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148806914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike conventional trucks, ATs are characterized by advanced lane-keeping capabilities, reduced lateral wander, and the potential for longer operating hours due to reduced reliance on human drivers. While these features offer promising gains in traffic efficiency and safety, they may also result in concentrated, repetitive loading along narrow wheel paths—posing challenges for traditional pavement designs. This paper presents a narrative literature review exploring the potential implications of autonomous truck (AT) operations on pavement bearing capacity and performance, synthesizing findings from experimental studies, mechanistic–empirical analyses, and emerging modeling frameworks. The discussion addresses the limitations of existing pavement design and maintenance methodologies in capturing these emerging loading scenarios and highlights the need for updated modeling approaches that reflect the unique characteristics of autonomous vehicle behavior. Additionally, the study outlines critical areas for future research, including performance monitoring, infrastructure adaptability, and integration with intelligent transportation systems.

On the one hand, Non-Destructive Testing (NDT) offers the potential for non-invasive and quick inspections. On the other hand, the peculiarities and brittleness of concrete material might additionally require destructive testing, i.e., coring to retrieve material properties in the laboratory. On these grounds, the present study aimed to demonstrate an optimization framework for the condition assessment of concrete pavements at toll stations. The framework first included non-invasive deflectometric testing with the most popular deflectometric method, that of the Falling Weight Deflectometer (FWD). Based on the condition mapping provided by the FWD, a second approach followed with selective locations for coring to determine concrete thickness and strength.

This study examined Bane NOR SF track inspectors’ visual assessment practice to evaluate consistency, identify subjective biases, and suggest improvements. During the winter of 2025, the inspectors participated in semi-structured interviews to share their experiences with visual inspections. To assess consistency, each inspector described and rated ballast defects in a series of images. Results revealed significant variability in how inspectors assess ballast conditions and determine maintenance urgency. While severe mud pumping and missing ballast shoulders were consistently rated as requiring immediate action, evaluations of other defects varied widely. This inconsistency highlights the uncertainty inherent in visual inspections, introducing bias into maintenance planning and associated costs. Notably, the results show that recommended maintenance deadlines are often influenced by practical constraints (available resources or local feasibility), further increasing variation that must be accounted for when comparing defects across time and regions. To improve reliability and efficiency, this study suggests improved standardization and training, and integration of supplementary objective technologies to enhance ballast bed evaluations.</div></div>","PeriodicalId":101261,"journal":{"name":"Transportation Research Procedia","volume":"99 ","pages":"Pages 623-630"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148807008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two sections of an experimental road, each measuring 40 m in length, were built with a 30 cm cement-stabilised CDWA subbase, with each section using a different cement type.

Samples cured for 7 and 28 days were also tested in the laboratory to measure their compressive strength and resilient modulus values. Field measurements showed statistically equivalent surface moduli between the two cement-stabilised materials. The laboratory test results confirmed that the two mixtures had comparable strength and stiffness values. Life cycle analysis revealed that using CEM-IV/B instead of CEM-II/B for CDWA stabilisation resulted in a 16% reduction in its climate change impact.

This paper reviews heavy vehicle loading characteristics in Europe, highlighting differences between national and international haulage, regulatory frameworks, and the prevalence and causes of vehicle overloading. The role of traffic loading measurement technologies is examined, with emphasis on static weighing, pavement-based Weigh-In-Motion (WIM), and Bridge Weigh-In-Motion (B-WIM) systems, including their accuracy, applicability, and limitations. The application of WIM data in pavement engineering is discussed, focusing on axle-load spectra, equivalent axle-load concepts, and mechanistic-empirical design approaches that enable realistic fatigue and rutting predictions. For bridges, advanced traffic load modelling, dynamic amplification assessment, and soft load testing using B-WIM are presented as effective tools for evaluating ageing and deteriorated structures under real traffic conditions.
