The application of in-place recycling techniques has emerged as a practical and effective way to enhance the sustainability agency pavement management decisions for asphalt-surfaced pavements. However, potential environmental benefits resulting from applying have not been fully documented in literature. This paper presents comprehensive life cycle assessment (LCA) model that extends typical LCA's system boundaries include impacts usage phase production energy sources. results LCA specific...

The pavement maintenance and rehabilitation (M&R) strategy selection problem is an exceedingly hard to solve optimally. In this paper, a novel Adaptive Hybrid Genetic Algorithm (AHGA) proposed which incorporates Local Search (LS) techniques into Algorithms (GA) improve the overall efficiency effectiveness of search. Specifically, it contains two dynamic learning mechanisms guide combine exploration exploitation search processes adaptively. first mechanism aims assess worthiness conducting LS...

Road transportation has always been inherent in developing societies, impacting between 10–20% of Gross Domestic Product (GDP). It is responsible for personal mobility (access to services, goods, and leisure), that why world economies rely upon the efficient safe functioning facilities. maintenance vital since need increases as road infrastructure ages based on sustainability, meaning spending money now saves much more future. Furthermore, plays a significant role safety. However, pavement...

Different techniques for measuring pavement surface macrotexture and their application in management are discussed. The main applications of to measure the frictional properties detect hot-mix asphalt (HMA) construction segregation or nonuniformity. Since macro-texture can be measured quite efficiently using noncontact technologies provides important information regarding safety HMA quality, this parameter may included quality assurance control procedures. Correlations between different...

The potential risk of climate change raises interest in how it may affect the deterioration rates flexible pavements and pavement service lives would be altered as a consequence. Previous studies demonstrated that temperature is most influential environmental factor for Mechanistic–Empirical Pavement Design Guide. In this study, factors, both increase average annual seasonal variation temperature, are examined through sensitivity analysis. performance to well other factors such...

AbstractDespite the general consensus among stakeholders on how useful life cycle assessment (LCA) methodology can be in helping to reduce environmental burdens of a road pavement, very few pavement LCA models have considered entire cycle. This paper presents development highly customisable tool that provides an integrated, project-level approach includes all six phases. The developed encompasses main modules, including extraction raw materials and production; construction, maintenance...

Tire–pavement friction is a factor that can affect the rate of vehicle crashes. Several studies have suggested reduced during wet weather conditions, due to water on pavement surface reducing contact area between tire and pavement, increases This study evaluates effect both wet- dry-condition The data for were provided by New Jersey Department Transportation. Regression analysis was performed verify crashes various types urban roads. It found not only associated with wet-condition crashes,...

Addressing the multidimensional challenges involved in advancing sustainability of pavement systems requires development optimisation-based decision support system (DSS) for management with capability to identify optimally sustainable maintenance and rehabilitations (M&R) strategies. The main objective this research work is develop a multi-objective optimisation framework that hosts comprehensive integrated life cycle costs–life assessment model covers pavement's whole cycle, from extraction...

Infrastructure management decisions, such as condition assessment, performance prediction, needs analysis, prioritization, and optimization are often based on data that is uncertain, ambiguous, incomplete incorporate engineering judgment expert opinion. Soft computing techniques particularly appropriate to support these types of decisions because very efficient at handling imprecise, incomplete, subjective data. This paper presents a review the application soft in infrastructure management....

Pavement preservation programming often involves multiple objective considerations. Traditional single-objective optimization frameworks consider one single while imposing competing objectives as constraints in the formulation. This paper proposes an approach for pavement that uses multiobjective and chance constraints. can handle incommensurable conflicting considering probabilistic related to available budget over planning horizon. The implementation of a case study with two of: (1)...

Characterisation of pavement surface texture has significant effects on ride comfort and road safety. Pavement is typically reported as a single attribute, such mean profile depth, root square roughness or hydraulic radius, which limits the usefulness information extracted from measurements. Therefore, advanced methods that characterise in three dimensions are needed. This paper reviews recent advances development two imaging-based evaluation methods. The main objective these to recover 3D...

Optimization-based tools have been included in many engineering management systems for individual infrastructure asset classes such as pavement (PMS) and bridge (BMS). These typically include single-objective optimization analyses. However, real-world decisions concerning preservation renewal often involve more than one objective reflecting the various goals of agency need to evaluate possible alternatives according multiple criteria. Traditional approaches handling situations optimize a...

Researchers have studied the vulnerability of roadway systems to disasters, such as terrorist attacks or natural disasters. However, literature has not explicitly addressed other factors, infrastructure condition, that can significantly affect systems. In this study, authors developed an algorithmic framework address how condition a network affects its disruptions. The was computed with respect two measures: efficiency and vehicle miles travel. results show average roadways in network,...

Abstract Continuous deflection devices (CDDs) can safely measure pavement (or other related properties) while traveling at highway speed, which reduces traffic disruption. CDD measurements are contaminated with relatively high noise levels compared to stop‐and‐go such as the Falling Weight Deflectometer. In this article, we use wavelet transform denoising remove and estimate true slope obtained from Traffic Speed Results show that failure denoise lead calculated Effective Structural Number...
