Abstract. The evaluation of the structural condition of a pavement is of great importance, since pavements are important transportation infrastruc-tures that should have an adequate bearing capacity. For this reason, the use of Non-Destructive Testing (NDT) systems has gained worldwide ac-ceptance as an effective tool for determining pavement condition. Various indices from deflection...
Abstract: Longitudinal cracks can influence the spread of stress in pavement structure, thereby affecting the pavement deflections. The effects of longitudinal cracks on the falling weight deflectometer (FWD) deflections of pavements with granular base (GB) were investigated and evaluated in this study. The finite element method (FEM) was used to simulate the intact and longitudinal-cracked...
Abstract. This study conducted in Kitchener, Ontario, presents a comprehensive analysis of monitoring the environmental and structural behaviour for two years in an instrumented pavement test section. Focusing on pressure, strain, moisture, and temperature measurements throughout the pavement structural layers, the re-search uncovers nuanced patterns. Temperature fluctuations exhibit distinct...
Abstract. Pavement-integrated dynamic wireless power transfer (DWPT) can deliver electrical power to electric vehicles (EVs) as they transverse the roadway. However, a thorough investigation is needed to assess the mechanical behavior of pavement structures containing DWPT components. For the work reported herein, a flexible pavement with embedded DWPT components was constructed in an...
Abstract. Performance monitoring of highway infrastructure is vital for the integrity of the transport network and the safety of the users. The satellite remote sensing technology can task itself to further enhance the standards and monitoring capabilities of Non-Destructive Testing (NDT) methods, in terms of allowing full network-level coverage and a regular revisit of the infrastructure....
Abstract. Integrating new technologies in civil engineering has gained more space, particularly in pavement engineering. By overcoming some gaps that older strategies present, such as purely visual inspection, and by transforming the roads into a structure connected to network managers that permanently transmits data, it is possible to get a better knowledge and understanding of how pavements...
