Abstract

Korištenje željezničkog prometa pruža nam sigurnost, brzinu i udobnost vožnje govoreći o putničkom prometu, ali isto tako i odličan izbor teretnog prijevoza velikih količina tereta uz niske troškove. Za sve to treba osigurati kvalitetan gornji ustroj koji preuzima prometna opterećenja, a željeznički pragovi imaju važnu ulogu u tome. Armirano betonski pragovi su jedna od glavnih vrsta željezničkih pragova s rastućom primjenom u budućnosti, ponajviše zbog svoje velike čvrstoće, otpornosti na vanjske utjecaje i dugim vijekom trajanja zbog čega prednjače drugim vrstama pragova. Analizirane su osnovne karakteristike željezničkih pragova s naglaskom na armirano betonske i njihova usporedba s ostalim vrstama pragova. Također, prikazan je pregled armirano betonskih pragova kod suvremenih kolosiječnih konstrukcija na čvrstim podlogama, njihova moguća primjena na željeznici s velikim brzinama te način i mjesta njihove ugradnje.

Abstract (english)

The use of rail transport gives us safety, speed and comfort of driving when talking abou passenger traffic, but also an excellent choice of freight transport of large quantities of cargo at low cost. For all this, a quality track that takes on traffic loads needs to be ensured, and railway sleepers play an important role in this. Reinforced concrete sleepers are one of the main types of railway sleepers with increasing application in the future, mainly due to their high strength, resistance to external influences and long service life, which is why they are ahead of other types of sleepers. The basic characteristics of railway sleepers with an emphasis on reinforced concrete and their comparison with other types of sleepers are analyzed. Also, an overview of reinforced concrete sleepers as modern track structures on solid bases, their possible application on high-speed railways and the method and place of their installation are presented.
