Road transportation significantly contributes to urban NOx pollution, with concentrations reaching 100–1000 ppb near high-traffic areas. This study provided a comparative assessment of TiO2 incorporation methods (mixing and surface coating) in asphalt pavement, while examining the effects of environmental factors on NOx and NO degradation. While as...

Physical hardening (PH) significantly affects bitumen's low-temperature performance. This paper investigates the effect of oxidative aging and wax structure on PH using 4-mm dynamic shear rheometer (4-mm DSR) and differential scanning calorimetry (DSC) tests. The results show that the wax chain length has a pronounced effect on the PH. Short-chain...

The resilience of pavements depends not only on asphalt mixture performance and structural design but also on the bonding between two adjacent pavement layers and interlayer performance as well as on traffic and environmental conditions. This paper thus aims to assess the impacts of several parameters on the interface shear resistance. Accordingly,...

Resilience in general captures the goals of maintaining the continuity of performance and recovery to the desired function during an infrastructure designated service life. Nevertheless, pavement infrastructure is particularly vulnerable to the impacts of climate change due to being continuously exposed to outdoor conditions. Constructing a pavemen...

Latex as an asphalt modifier has gained popularity in the asphalt industry as it improves the durability of asphalt pavement. However, the elastomeric properties of latex stiffen the asphalt binders, resulting in additional energy consumption during the production of asphalt mixtures, which may cause a higher emission of greenhouse gases. This is u...

The demand for durability and resilience in asphalt pavements has led to the progressive implementation of performance-enhancing technologies like bitumen modification using polymers or fibers. This is particularly important in a port environment, where roads are subjected to heavy traffic. The main objective of this study is to contribute to the c...

Numerous factors may disrupt pavement construction including human errors and unforeseen changes in the environmental conditions. These incidents can shorten pavement life span. New technologies recently came to the aid of contractors and road agencies to detect and possibly mitigate undesirable impacts of unpredictable incidents during the asphalt...

It is known that pollutants and their irreparable influence can considerably jeopardize the environment and human health. Such disastrous, growing, hazardous particles urged researchers to find effective ways and diminish their destructive impacts and preserve our planet. This study evaluates the potential of incorporating Titanium Dioxide (TiO2) s...

This paper evaluates the performance of fiber-reinforced mixtures subjected to moisture damage. Response Surface Method was used to design an experimental matrix based on the central composite design. The amounts of fibers, number of freeze and thaw cycles, and testing temperatures were considered as factors, while maximum load, stiffness, indirect...

Hot mix asphalt (HMA) is a common material that has been largely used in the road construction industries. The main constituents of HMA are asphalt binder, mineral aggregate, and filler. The asphalt binder bounds aggregate and filler particles together and also waterproofs the mixture. The aggregate acts as a stone skeleton to impart strength and t...

The increasing expectations on industries to contribute to the circular economy has also encouraged the interest in finding solutions for reducing and re-using secondary materials. This interest is driven by environmental, technical, or economical considerations. As for any development, performance, durability, and all other aspects of sustainabili...

In this study, an innovative methodology is proposed to characterize the short-term aging of asphalt binders using matrix analysis method. The rotational viscosity and complex shear modulus of asphalt binders were chosen as target rheological properties for the analysis of aging. A set of square matrices was developed based on test temperatures and...

The impact of aging on asphalt binder depends on multiple factors including binder type and environmental conditions. In a previous study, Shalaby proposed two empirical equations to investigate the effects of extended short-term aging on the shear modulus and phase angle of asphalt binders. The objective of this study was to use a robust mathemati...
