Hydro-Québec is a Quebec Crown corporation managing the generation, transmission and distribution of electricity in Quebec. In addition to all hydraulic structures, generation and transmission facilities, more than 3,000 km of roads are under its responsibility, and are considered an asset for the company. These roads are spread throughout Quebec but are mostly located north of the 50th parallel. [...]

Residual soil and weathered rock slopes are typically found in mountainous and hilly terrains in most tropical regions like Thailand and ASEAN countries. These earth slopes are often in the unsaturated condition with negative pore-water pressure or matric suction. When the rainfall infiltrates into slope, the pore-water pressure increases, the matric suction decreases, and thus reducing the slope [...]

British Columbia, like much of Canada, has numerous rural highways serving local communities, First Nations, industry, and tourism. Many of these highways were initially constructed as temporary roads to access natural resources, resulting in minimal effort in constructing the road base, drainage, and geometric alignment. Consequently, the underlying roadbed often contains organic material like logs [...]

Abstract Management and maintenance of rural roads in the Pradhan Mantri Gram Sadak Yojna (“PMGSY”) has always been a challenge due to its vast PAN-India spread, absence of evidence-based objective monitoring mechanisms, and lack of financial resources with states.. This paper discusses the development and implementation of concept of Performance Assessment of roads during maintenance instead [...]

Rural roads, important to ensuring a well connected network for the rural population, are increasingly vulnerable to the impacts of climate change. The lower quality of infrastructure surface layers, mostly unpaved, and the lack of resilience to extreme weather conditions can significantly impact community access to main transport infrastructures, public facilities, like schools, hospitals, and markets, [...]

Abstract: Rural roads are essential for economic growth, social connectivity, and access to critical services. However, they are increasingly vulnerable to climate change impacts, including extreme weather events such as heavy rainfall, floods, droughts, and rising temperatures. These challenges result in soil erosion, pavement degradation, and infrastructure failures, particularly in developing [...]

On Japanese expressways, road surface damage frequently occurs due to the effects of climate change. During the summer, air temperatures can exceed 40°C, leading to issues such as rutting and blistering in asphalt pavements. On aging expressways, rainfall and heavy traffic accelerate pavement deterioration, resulting in the frequent occurrence of potholes. In winter, water infiltrates the pavement [...]

Slope erosion is a growing problem on mountain roads in Savoie. Climate change, with more frequent intense rainfall and freeze/thaw cycles at higher altitudes, is contributing to the acceleration of these phenomena. The impact on roads is significant, whether in terms of user safety, the structural durability of the infrastructure or the operating constraints generated. The Savoie department is working [...]

The Eastern Cape region faces challenges in constructing roads as a result of inadequate funding, a shortage of skilled labour, and environmental concerns. The purpose of this article is to make the case for the use of gravel roads in the Eastern Cape, bearing in mind the effects of climate change and the increasing demands of local communities for improved service. The objective is to examine the [...]

Road markings belong to roadway elements positively influencing road safety through delineating travel paths. For proper function, they must remain visible to road users. From materials perspective, road markings are systems comprising a paint layer and a glass beads layer, which protects the paint layer from abrasion and provides the key functional parameter of retroreflectivity. During wear and [...]
