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...

Recently, the reduction of environmental burdens related to highway infrastructures has been in spotlight. Within this context, use recycled materials bituminous mixtures for road pavement construction and maintenance potential mitigate excessive non-renewable resources. Nevertheless, material consumption is only one aspects that affects sustainability an infrastructure. Other relevant issues should be considered. The objective work evaluate impacts asphalt containing crumb rubber (CR)...

In this study a comparative life cycle assessment (LCA) was conducted according to 'cradle-to-laid' approach evaluate the potential environmental impacts related use of recycled concrete aggregates (RCAs) as partial replacement coarse natural in production Hot Mix Asphalt (HMA). Specifically, three percentages RCA replacements were analyzed: 15, 30 and 45%. Primary data collected mainly through surveys performed Colombian contractors from region Barranquila used model foreground system. The...

While temperature rises in urbanized area there is a growing concern among key decision-makers and urban planners to actively incorporate Urban Heat Island (UHI)-related considerations their development/design. However, given that the existing models (mainly physics-based) are too complex use, need for an easy-to-use decision support tool provides explicit understanding of contributions different planning decision-making parameters on UHI. To this end, research uses publicly available data...

Cement Treated Base (CTB) is a mixture of aggregates, Portland cement and water that hardens through curing to create strong durable material widely used as base course in road pavement construction. This layer can be either flexible or rigid pavements, the range possible materials CTB has been recently expanded include Reclaimed Asphalt Pavement (RAP). Despite considerable use there only limited information regarding its environmental performance, especially when RAP added. paper presents...

Data-driven models serve as valuable tools for understanding and tackling the UHI phenomenon that can provide user-friendly platforms urban planners incorporating considerations in their decisions. This study aims to assess generalizability of data-driven at street-level resolution, particularly considering various similarity degrees contexts between training testing cities. Five cities from three countries were selected encompass a diverse range similarities this comparative study. Random...

Abstract Despite the fact that it considers a design period of 20 years for flexible pavements, Portuguese manual pavement structures states importance making life-cycle cost analysis (LCCA) no less than 40 years, called project period, in order to compare different solutions terms global costs final choice structure national road or highway. The problem is until now this has never been done Portugal. This paper presents new LCCA system based on an optimisation model considering performance,...

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...

Sustainability is becoming a key factor in the decision-making process of infrastructure projects throughout their lifecycles. In particular, Environmental Impact Assessment (EIA) design phase matter significant importance, for both public and private sectors, given long-term impacts decisions on environmental performance projects. Traditionally, EIA performed by sustainability expert at end cycle, which time modification costly time-consuming. recent years, Building Information Modelling...

Abstract Pavement design and management practices must be adapted in response to future climate change. While many studies have attempted identify different methods adapt pavements conditions, the potential economic impacts of adaptations still remain largely unquantified.
