The reduction in the ability of bitumen to bond with aggregate surface due infiltration moisture has been recognised for years, and this deterioration phenomenon is called damage. In general, loss bonding between shortens service life top layer pavement. Many investigations have conducted understand mechanisms damage strength find ways improve strengthen mitigate effect moisture. This paper reviews extensive literature on bitumen-aggregate asphalt mixtures. general description theories that...
Any transportation infrastructure system is concerned with durability and performance issues. The proportioning uniformity control of concrete mixtures are critical factors that directly affect the longevity pavements. Currently, only means available to monitor mix proportions any batch track tickets created at plant. This does not take into account potential errors in loading materials storage silos, calibration errors, addition water after dispatch. Therefore, there a need for rapid,...
The cost of road construction consists design expenses, material extraction, equipment, maintenance and rehabilitation strategies, operations over the entire service life. An economic analysis process known as Life-Cycle Cost Analysis (LCCA) is used to evaluate cost-efficiency alternatives based on Net Present Value (NPV) concept. It essential above-mentioned aspects in order obtain optimum pavement life-cycle costs. However, managers are often unable consider each important element that may...
Various models have been developed over the past several decades to predict dynamic modulus ∣E*∣ of hot-mix asphalt (HMA) based on regression analysis laboratory measurements. The most widely used in community today are Witczak 1999 and 2006 predictive models. Although overall accuracies for these existing as reported by their developers quite high, generally tend overemphasize influence temperature understate other mixture characteristics. Model accuracy also tends fall off at low high...
Structural health monitoring of civil infrastructures is a difficult task, often impeded by the geometrical size monitored systems. Recent advances in conducting polymers enabled fabrication flexible sensors capable covering large areas, possible solution to challenge mesoscale The authors have previously proposed novel sensor consisting soft elastomeric capacitor (SEC) acting as strain gauge. Arranged network configuration, SECs potential cover very surfaces. In this paper, understanding...
Abstract This paper reports on a simple and versatile method for patterning transferring graphene‐based nanomaterials onto various types of tape to realize flexible microscale sensors. The involves drop‐casting graphene film prepatterned polydimethylsiloxane (PDMS) surface containing negative features by suspensions, applying Scotch remove the excess from nonpatterned areas PDMS surface, then patterned inside at target tape. feature size transferred patterns final is as small few...
This paper reports on the procedures of mix design preparation, production, placement, and performance evaluation first electrically conductive concrete (ECON) heated-pavement system (HPS) implemented at a U.S. airport. While ECON has drawn considerable attention as paving material for multi-functional pavements, including HPS, majority HPS applications studies have been limited to laboratory scale or include materials/methods that do not conform regulations enforced by airfield construction...
The authors have recently developed two novel solutions for strain sensing using nanocomposite materials. While they both aim at providing cost-effective the monitoring of local information on large-scale structures, technologies are different in their applications and physical principles. One sensor is made a cementitious material, which could make it suitable embedding within core concrete structures prior to casting, resistor, consisting carbon nanotube cement-based transducer. other can...
Millions of dollars are annually spent for ice or snow removal from the roadways and airport paved surfaces in cold regions. The presence on areas can cause traffic accidents financial loss because flight cancellations delays. For mitigating winter pavement maintenance issues, use superhydrophobic (super-water-repellent) coating techniques is gaining attention as a smart cost-effective alternative to traditional practices. This study focuses creating, characterizing, evaluating innovative...
Maintenance activities and pavement rehabilitation require the allocation of massive finances. Yet due to budget shortfalls, stakeholders decision-makers must prioritize projects in maintenance rehabilitation. This article addresses prioritization alternatives by integrating fuzzy analytic hierarchy process (AHP) with VIKOR method (which stands for 'VlseKriterijumska Optimizacija I Kompromisno Resenje,' meaning multi-criteria optimization compromise solution) decision analysis (MCDA)...
This paper reports on all-flexible strain sensors made of graphene, microfluidic liquid metal, and stretchable elastomer. These graphene feature a flexible wiring design, where metal is introduced into channels for inside the devices. design allows enhanced overall structural flexibility reduced risk stress-related mechanical failure sensors, at contact areas between sensing elements wires. A unidirectional sensor multidirectional rosette are developed, by encasing patterned with We...
