Abstract: In order to reduce costs and time associated with road quality assessment, a Pavement Management System (PMS) must embrace survey methods that expedite processes and minimize the demand for expensive procedures. With the widespread use of smartphones, numerous studies leverage these tools to simplify measurement processes. Additionally, the integration of computer vision (CV) with...
Abstract. This study explores the efficient identification of geogrids in road pavements through ground-penetrating radar (GPR) and comprehensive laboratory experiments. Geogrids are crucial in enhancing pavement strength and durability, making their effective detection vital for mainte-nance and longevity. GPR, based on electromagnetic principles, offers a non-destructive and insightful...
Abstract. The work presents the setup of a full-scale trial site to summa-rize a case study realised within the University of Palermo. A full-scale area has been designed and constructed to test, on a large scale, a pave-ment structure equipped with sensors for continuous and in real-time monitoring and of various, crucial parameters, i.e., deformation, tempera-ture, and pressure, which are...
Abstract. The International Civil Aviation Organization (ICAO) recently developed the ACR-PCR method for reporting the bearing capacity of airport pavements. From November 2024 all paved runways, taxiways, and aprons will have to be assed according to the new ACR-PCR method. The ACR-PCR will replace the ACN-PCN method, that has been worldwide used over the last four decades and is a critical...
Abstract. In the present study, the effects of adding crumb rubber modifier from end of life tires on the mechanical, functional, acoustical and environmental properties of asphalt mixtures were investigated in situ. Four different dense mixtures, characterized by similar gradation curve and optimally designed in laboratory using the volumetric method, were laid on a real test field in...
