The primary objective of this research is to evaluate the feasibility of several WMA mixtures as potential asphalt paving mixtures for Nebraska pavements. To that end, three well-known WMA additives (i.e., Sasobit, Evotherm, and Advera synthetic zeolite) were evaluated. For a more realistic evaluation of the WMA approaches, trial pavement sections of the WMA mixtures and their HMA counterparts ...

In general, the physical and rheological properties of asphalt binder are directly affecting resistance mix to permanent deformation (rutting), water damage, thermal cracking. The degradation in these leads severe distresses that appear pavement and, consequently, make repair maintenance very expensive. Since modified-asphalt cement may help minimize such aforementioned distresses, this researc...

Pavement maintenance plays a significant role in megacities. Managing complaints and scheduling road reviews are the two concerns under intelligent pavement management system (PMS) plan. In contrast, if damages not treated immediately, they will increase over time. By leveraging accurate data from sensors, smart PMS improve capability, support sustainability, drive economic growth network. This...

This paper presents an overview of observed distresses on low slope roofing systems collected for the Building Envelope Life Cycle Asset Management (BELCAM) project. The data include over 14,000 visible distresses from 600 roofs from seven different climatic regions across Canada. The distresses encountered for built up roofs, modified bituminous roofs and a limited number of single-ply roofing...

One of the most common pavement distresses in flexible is rutting, which mainly caused by heavy wheel load and various other factors. The prediction rutting depth important for safe travel long-term performance pavements. Factors that are considered this paper rut Temperature, Equivalent Single Axle Load, Resilient modulus, Thickness hot mixed asphalt. input data all factors collected from Long...

Abstract Climate attributes such as precipitation, extreme temperature, and freeze-thaw cycles along with traffic loads cause pavement distresses. The maintenance need for pavements is decided based on the condition rating International Roughness Index (IRI). Generally, an IRI less than 2.68 m/km acceptable, a greater considered unacceptable classified “very poor” of pavement. It imperative to ...

Pavement distress data in a single section usually presents long-tailed distribution, with potholes, sealed cracks, and other distresses normally located at the tail. This distribution will seriously affect performance robustness of big data-driven deep learning detection models. Conventional augmentation algorithms only expand amount by image transformation fail to enlarge diversity. Due such ...

Scrap tire rubber and nylon fiber are waste materials that could potentially be recycled used to improve the mechanical properties of asphalt pavement. The objective this research was investigate scrap (R-F) modified warm mix mixture (WMA). high-temperature performance estimated by Hamburg wheel-tracking testing (HWTT) device. low-temperature cracking evaluated disk-shaped compact tension (DCT)...

Abstract Asphalt pavements have been extensively used in highway system. However, a great number of asphalt suffer from early distresses after servicing for about 2–3 years, which leads to frequent rehabilitation and increased maintenance cost. To understand the damage propagation principle correlated measure, progress pavement distress rehabilitation, structural performance, assessment has exp...
