Budapest Közút is developing ROad Data Information System based on mobile laser scanning since 2013. All public roads (cca. 5000 km) are surveyed by MLS (Riegl VMX450) in survey grade accuracy and all visible road assets has been digitized and loaded to a complex 3D GIS environment. Since the first full coverage had been done in 2014 the whole city has also been updated - being one of the few l...

Road building on geologically vulnerable slopes can trigger erosion, mass wasting and sedimentation. Disturbance of the natural drainage systems and making deep cuts and fills across already fragile slopes are the main causes. This often leads to excessive land degradation of land areas adjacent to the road. These effects have a direct bearing on the livelihoods of people who survive by subsist...

Today, during the life of an open pit mine, million tons of materials, including waste and ore, are displacing by truck fleets. In the case of a shallow ore deposit, which is located up to 300 meters to the ground surface, depending on preliminary equipment size and capacity, it will take three to five years to remove overburden and waste rocks to expose the ore body. In that period, the main w...

below the surface through scarifier teeth. Emulsions and medium-curing and slow-curing asphalts were used. The travelling plant-mix was not entirely satisfactory because of conditions existing on this project. It is necessary to have the windrow of material quite wet in order to get it through the travelling pug-mill mixer. The project was built late in the fall, and the water did not evaporate...

Extended abstract 1- Introduction     Forest is a sustainable ecosystem with a high balance, and is characterized by non-eroded soils and sediment-free water. Forest roads serve as the largest construction activities and a component added to the forests which are required for the accessibility to forests and forest resources, logging, transportation, conservation, tourism, etc. However, these...
