Secondary title:	Traffic loadings on pavement
Secondary abstract:	The measurement of realistic traffic loadings is essential to successfully manage roads. In the Republic of Slovenia, engineers have tried to get a real number of vehicles with counting data for over 30 years now. Specifications about axle thrust and vehicle weight we estimate with TSC 06.511. In recent years we have accumulated realistic traffic loadings with weigh in motion systems (WIM system). WIM systems give accurate information about vehicle weight, because they weigh all the vehicles in optional traffic stream. Main reasons for difference in equivalency factor between counting data and weigh-in-motion (WIM) systems are overloaded axles and increase of traffic. These differences have influence on design traffic loadings calculation that are important for design and assessment of pavement, bridges and traffic studies. In this degree, we tried to verify these differences in road section Benedikt 3 - 0315. First we compared data (number of vehicles, equivalency factor) that we got from measurements. After that we calculated design traffic loadings. On the basis of design traffic loadings, we read graph dimensions of new asphalt pavement layers and calculate the pavement thikness- index. The result has shown that the dimension of surfacing between counting data and eight- in-motion systems is 1,8 centimetres.

Abstract (ePrints):	Za uspešno upravljanje s cestami in objekti na njih moramo poznati realne prometne obremenitve. V Republiki Sloveniji že več kot 30 let pridobivamo podatke o številu vozil z avtomatskimi števci prometa. Podatke o skupnih masah in osnih potiskih vozil pri poznani strukturi prometa pa nato ocenimo po Tehnični specifikaciji za prometne obremenitve (TSC) 06.511. V zadnjem času točne podatke o prometnih obremenitvah in obremenitvah vozil pridobivamo s pomočjo sistemov za tehtanje vozil med vožnjo (WIM sistemov). WIM sistemi tehtajo vsa vozila v prostem prometnem toku in so edini tehtalni sistemi, ki zagotavljajo zanesljive, neizkrivljene podatke o težah vseh tovornih vozil. Razlike med faktorji ekvivalentnosti (FE) iz TSC 06.511 in faktorji dobljenimi s pomočjo tehtanj se pojavljajo zaradi povečanja prometa, zaradi vedno večje izkoriščenosti vozil in preobremenjenosti vozil. Razlike v faktorju ekvivalentnosti pa dodatno povečajo razliko v izračunu merodajne prometne obremenitve, ki je potrebna za dimenzioniranje novih in vrednotenje obstoječih cest. V diplomski nalogi smo te razlike preverili na konkretnem primeru odseka ceste Benedikt 3 – 0315. Primerjali smo podatke med števci in sistemi za tehtanje (število vozil, faktor ekvivalentnosti), ki smo jih dobili na podlagi 7 dnevnih meritev. Izračunali smo merodajno prometno obremenitev in na podlagi te določili (iz diagrama) dimenzije osnovnih plasti novih asfaltnih voziščnih konstrukcij ter izračunali debelinski indeks. Rezultat je pokazal, da se debelini krovnih plasti na podlagi podatkov števcev in sistemov za tehtanje razlikujeta za 1,8 cm.
