Abstract

Prometno opterećenje ima značajan utjecaj na brzinu procesa degradacije kolničke konstrukcije. Zbog toga je prilikom dimenzioniranja kolničke konstrukcije, pored podataka o broju vozila, nužno poznavanje njihovih masa ili osovinskih opterećenja. Analizom prometnog opterećenja dolazi se do broja ekvivalentnih osovina kojima se izražava projektno prometno opterećenje. Postupak analize prometnog opterećenja za asfaltne kolnike u Republici Hrvatskoj provodi se prema normi HRN U.C4.010. Analiza utjecaja preopterećenja vozila na životni vijek kolničke konstrukcije je vrlo važna u pogledu osiguranja sigurnosti i trajnosti cesta. Preopterećenje vozila odnosi se na situaciju kada vozilo prelazi dopuštenu nosivost ceste, što može uzrokovati oštećenja na kolniku. Ključni faktori koji se moraju razmotriti u analizi utjecaja preopterećenja vozila na životni vijek kolničke konstrukcije su: nosivost kolnika, materijali od kojih je kolnik izgrađen, deformacije i pukotine, rutinsko održavanje, učestalost preopterećenja te pravila i propisi. Kako bi se smanjio utjecaj preopterećenja vozila na životni vijek kolničke konstrukcije, važno je sustavno pratiti stanje cesta, educirati vozače o važnosti poštivanja ograničenja nosivosti i ulagati u redovito održavanje i obnovu infrastrukture. To će doprinijeti povećanju sigurnosti prometa i produžiti životni vijek cestovnih površina.

Abstract (english)

Traffic load has a significant impact on the rate of pavement construction degradation. Therefore, when designing pavement construction, in addition to data on the number of vehicles, knowledge of their weights or axle loads is necessary. By analyzing the traffic load, the number of equivalent axes expressing the design traffic load is determined. The procedure for analyzing traffic load for asphalt pavements in the Republic of Croatia is conducted according to the standard HRN U.C4.010. Analyzing the impact of vehicle overloading on the lifespan of pavement construction is an important aspect of study to ensure the safety and durability of roads. Vehicle overloading refers to the situation when a vehicle exceeds the permissible road load capacity, which can cause damage to the pavement. Key factors to consider in the analysis of the impact of vehicle overloading on the lifespan of pavement construction include: pavement capacity, materials used in pavement construction, deformations and cracks, routine maintenance, frequency of overloading, and regulations. In order to reduce the impact of vehicle overloading on the lifespan of pavement construction, it is important to systematically monitor the condition of roads, educate drivers about the importance of adhering to load capacity limits, and invest in regular maintenance and infrastructure renewal. This will contribute to increasing traffic safety and extending the lifespan of road surfaces.
