There are two technologies for road construction, e.g. an asphalt one and a concrete one, that exist in the market of road infrastructure at the moment and they both have their advantages and disadvantages [prof Jan Deja of Krakow Mining Academy, Cathedral of Building Materials Technology].The advantage of concrete pavement consists of the fact that it doesn't require bigger financial expenditures within 10 -20 years of exploitation (provided that necessary pavement maintenance treatments are

It leads to the question: which of these technologies should be chosen, which is better? The work hereby carries on analyses concerning a comparison of the technologies for road constructions; the asphalt one and the concrete one. Based on the analyses carried out with the use of the Hellwig method it was found that the achieved values of synthetic meters for asphalt and concrete pavements are close to each other, which may indicate that both technologies are comparable within the sectors taken for analyses in relation to accepted technological-technical and usability features. Roads in Poland, as viewed by the law, are divided into public roads and internal roads A public road is a road included in one of the following categories: community road, district road, provincial road and state road. The length of public roads (at the end of 2016, as shown by Statistics Poland GUS [1, 4] ) is 420 236.10 km. Out of these, 400 848.0 km (i.e. 95,4%) are administered by territorial self-government units General Director for National Roads and Motorways, 28 920.40 km -by the provincial administration, 124 944.60 km -by the district administration and 264 983.0 by the community selfgovernment, i.e. chief officer (mayor). Within the borders of bigger towns (municipal district type units) all public roads, except motorways and express roads are administered by a town's mayor.
