Asphalt pavement surfaces contribute significantly to the urban heat island effect. Their relatively high temperature, caused by absorption of solar energy, results in emission of heat to the surrounding air, leading to a rise in its temperature, deterioration of its quality, and an increase in energy consumption of the surrounding buildings. The proposed concept is that the heat from the pavem...

This study integrates ground spectrometry, imaging spectrometry, and in-situ pavement condition surveys for asphalt road assessment. There is strong spectral evidence for asphalt aging and deterioration processes, hence field spectra showed that asphalt aging and deterioration produce measurable changes in spectra as these surfaces undergo a transition from hydrocarbon dominated new roads to mi...

Each of pavements’ life cycle phases such as material extraction, transportation, construction, operation, rehabilitation, and end-of-life emits greenhouse gases. Such emissions can be influenced by climate change via changes in the rates of pavement deterioration and thus intensity and frequency of maintenance and rehabilitation. However, climate change has not been given full considerations i...

Pavements are important assets to the safety and serviceability of road networks. Due to their fast deterioration and stringent municipal budgets, allocating the limited rehabilitation funds becomes a complex task. In this paper, an efficient heuristic approach for fund allocation has been introduced. After prioritizing pavements based on different criteria, such as AADT, pavement IRI, and road...

This paper presents a mathematical programming model for optimal pavement rehabilitation planning. The model maximized the rehabilitation area through a newly developed permutation algorithm, based on the procedures outlined in the harmony search (HS) algorithm. Additionally, the proposed algorithm was based on an optimal solution method for the problem of multilocation rehabilitation activitie...

Infrastructure systems in the US are in an urgent need of maintenance and rehabilitation. According to the most recent factsheet published by the American Society of Civil Engineers, one of the top five infrastructure concerns of today in the US is transportation systems. The major challenge facing maintenance managers in state Departments of Transportation (DOTs) today is to preserve the road ...

The determination of pavement layer stiffness is an essential step in evaluating the performance of existing road pavements and in conducting pavement design and analysis using mechanistic approaches. Over the years, several methodologies involving static, dynamic, and adaptive processes have been developed and proposed for obtaining in-situ pavement layer moduli from Falling Weight Deflectomet...
