Opis:
Local roads (district and municipal) play an important role in the road network, especially in rural areas. In recent years, these roads have been largely repaired, which was often associated with the construction of new infrastructure. One of the basic conditions of maintaining the quality of road works is the proper construction or renewal of drainage devices. Errors in this area result in lower durability of the road pavement. It is equally important to maintain these devices later in a good technical condition, which requires spending appropriate funds from local government budgets. The aim of the study presented in the article was to determine the current technical condition of drainage of local roads in the Czestochowa region and to identify the most frequent design and implementation errors, resulting in a rapid loss of functionality of drainage devices. They were based mainly on in situ studies carried out in the area of an exemplary rural municipality. Errors resulting in the lack of continuity of drainage, or the danger of a rapid loss of its functionality are shown with real examples. It was found that despite the shortcomings described, in recent years the technical condition of drainage of local roads has improved, which is related to the systematic overhaul of local roads (including the construction of sidewalks) and the local government's perception of the importance of road drainage problem.

Opis:
Making transportation possible in forest areas is essential for forest management to ensure the protection of tree stands (fire access roads, forest monitoring) and use (in situ sales of wood), as well as for tourism and educational purposes. The units of the State Forests National Forest Holding optimize the spatial and quantitative network of roads, but as the manager of the National Treasury's assets, they must ensure that forest roads are in adequate condition. An attempt was made to analyze the technical condition of forest roads based on data from the Information System of the State Forests and to determine their repair and investment needs. Over 50% of all forest roads in the areas managed by the State Forests are still natural, unpaved roads, and 25% of them are considered to be in bad condition. The general technical condition of transportation routes is better, as roads providing unlimited traffic in good and satisfactory condition amount to 43,348 km (41% of all roads). 48% of main roads connected with public roads, which are the primary communication system of forest districts, are in good and satisfactory condition. The analysis shows that 24% (13,000 km) of main roads generally have a dirt surface or improved dirt surface, whereas 5,500 km of roads serving as fire access roads are in bad condition, requiring repair or reconstruction. The use of unpaved surfaces requires maintenance and repair work to ensure the ability to sustain load capacities and parameters enabling use by high−tonnage vehicles for timber hauling and extinguishing fires. It is estimated that on average 5.4% of roads need main− tenance work per year, which is equivalent to almost 5,760 km. The quantitative optimization of roads contributed to an increase in the importance and load of the current forest road network, where main roads represent 52% and fire access roads 47%, connected with the need to ensure appropriate technical parameters through the reconstruction of sections of roads.
