Abstract (english)
The base layer of a multi-layered pavement structure is often a cement-bound material, which combines an aggregate with cement binder. This load-bearing layer is quite rigid, which improves pavement properties, including frost resistance, and extends the life cycle of the pavement. In geographic areas with low temperatures and significant ground water, the bearing capacity of pavement structures can be reduced by volume deformations from freezing and thawing. Cold winters and frost-susceptible soil are present in eastern Croatia and in the city of Osijek. Thus, in this paper we examine the frost susceptibility of cement-bound aggregates, made with materials commonly used in Croatia, in accordance with the current Croatian standard HRN U.B1.050 and a new European standard EN 13286-54. The test mixtures did not meet the conditions for frost-resistant materials. To meet these conditions, one must use a higher cement ratio or a cement with a higher strength class.
Abstract (croatian)
Cementom stabilizirani materijal je nosivi sloj višeslojne kolničke konstrukcije, koji je kombinacija agregata s cementom kao vezivom. Ovaj nosivi sloj ima znatnu čvrstoću, poboljšava određena svojstva kolnika kao što su osjetljivost na smrzavanje te produljenje vijeka trajanja kolnika. Formiranje leda, volumne deformacije te gubitak nosivosti prilikom odmrzavanja u proljeće česta su pojava u područjima s niskim temperaturama i visokim razinama podzemne vode. Stoga je prilikom projektiranja kolničke konstrukcije u obzir potrebno uzeti ne samo prometno opterećenje, već i oštre klimatske i okolišne čimbenike. Hladne zime i tlo osjetljivo na mraz prisutni su u istočnoj Hrvatskoj i gradu Osijeku. Stoga ovaj rad istražuje osjetljivost na smrzavanje cementom stabiliziranog agregata prema staroj hrvatskoj normi HRN U.B1.050 i novoj europskoj normi EN 13286-54. Radi usporedbe ove dvije norme korišteni su materijali koji se uobičajeno koriste u Republici Hrvatskoj za izradu ovih slojeva. Rezultati su pokazali kako niti jedna mješavina ne zadovoljava uvjete postavljene normama te da je potrebno koristiti cement veće klase ili povećani udio cementa kako bi se dobio materijal otporan na utjecaj smrzavanja i odmrzavanja.
