“…Unsurfaced gravel roads constitute a significant portion of road networks in Brazil and other countries, necessitating substantial budget allocations for maintenance [20]. However, despite these investments, construction and maintenance efforts often fall short due to a lack of specialized technological knowledge among personnel.…”

This paper presents a novel system for the automated monitoring and maintenance of gravel runways in remote airports, particularly in Northern Canada, using Unmanned Aerial Vehicles (UAVs) and computer vision technologies. Due to the geographic isolation and harsh weather conditions, these airports face unique challenges in runway maintenance. Our approach integrates advanced deep learning algorithms and UAV technology to provide a cost-effective, efficient, and accurate means of detecting runway defects, such as water pooling, vegetation encroachment, and surface irregularities. We developed a hybrid approach combining the vision transformer model with image filtering and thresholding algorithms, applied on high-resolution UAV imagery. This system not only identifies various types of defects but also evaluates runway smoothness, contributing significantly to the safety and reliability of air transport in these areas. Our experiments, conducted across multiple remote airports, demonstrate the effectiveness of our approach in real-world scenarios, offering significant improvements over traditional manual inspection methods.

“…Brasil, que es un país que cuenta con la mayoría de sus vías de comunicación sin pavimentar, el mantener en buen estado estas vías muchas veces es muy costosa, y otras no se realizan de forma eficiente, pues el personal no maneja un buen trabajo técnico o aplicación de la tecnología adecuada. (Olivio Nervis & Peres Nuñez, 2019) Los objetivos de estos estudios son relacionar las dosificaciones de los estabilizantes tradicionales, mostrar las ventajas en el cambio de sus propiedades gracias al uso de estabilizadores, dar a conocer el ahorro de usar suelos estabilizados a comparación de otro material y generar tablas de comparación entre la literatura de revisión. El fin de estabilizar suelos es superar las condiciones (características, propiedades) de soporte ante determinadas cargas, entre las consecuencias de agregar aditivos obtenemos mayor durabilidad, resistencia, trabajabilidad del suelo, reducción de polvo, del espesor de pavimentos, impermeabilidad y control sobre el volumen de la masa.…”

El obtener un suelo mejorada ha sido por excelencia un producto en desarrollo constante, precisamente son los estabilizadores una alternativa de solución muchas veces indispensables para mejorar las características y propiedades de los suelos en obras viales. Es de conocimiento que en este tipo de obras se trabaja con material de préstamo o de canteras y muchas veces estos lugares están muy distantes del destino, lo cual incrementa los costos significativamente radicando acá el problema. Los objetivos de estudio giran en base al logro de relacionar las dosificaciones de los estabilizantes tradicionales, mostrar las ventajas de sus propiedades del suelo arcilloso mejorado después de ser estabilizados, mediante la comparación de dos casos de estudios ya realizados y dar a conocer el ahorro de usar estabilizadores de suelos. La investigación es de carácter descriptiva, pues se revisa y compara dos casos ya estudiados obteniendo la discusión y relación entre sus resultados.

“…Gravel roads play a critical role in agriculture, forestry, wildlife and tourism, fire control, search and rescue services, recreation, and cultural and historical heritage, and affect socioeconomic living conditions in rural areas ( 5 , 6 ), and therefore should be maintained at an acceptable level of service (LoS) ( 7 , 8 ). According to Apronti et al ( 9 ), around 69% of the road mileage in the U.S.A. consists of low-volume roads and taking traffic counts on such roads is not cost-effective.…”

Gravel roads form a significant share of the global road network, usually in sparsely populated rural areas. They are important, especially in agriculture, tourism, and forestry, connecting rural to urban areas. This systematic literature study comprises 105 reviewed publications on gravel road maintenance. Review articles on maintenance management practices, especially concerning objective condition assessment and data-driven methods (DDMs), are lacking. Therefore, this review provides a concise overview of current gravel road maintenance practices and ongoing research on objective condition assessment and DDMs for gravel road maintenance. It offers researchers in gravel road maintenance and other related fields a clear indication of where to focus their research efforts, as it suggests the direction for future research. Visual assessment methods are predominant for monitoring the condition of gravel roads, while objective methods and DDMs are not common. Research on gravel roads and their maintenance has increased in the last two decades, especially in North America and Northern Europe. Condition assessment is shifting from subjective to objective methods, utilizing knowledge from technological advancements in image processing, vibration and acoustics analysis, and so forth. There are some excellent research initiatives for objectively assessing the condition of gravel roads and DDMs, but the practical implementation is limited. Implementing objective assessment methods and DDMs generally improves the management of gravel roads with regard to decision-making, maintenance costs, safety, and the stability and comfort of the ride. Objective condition assessment and DDMs have the potential to enhance maintenance practices in the maintenance of gravel roads.
