Določitev gospodarnih omejitev osnih obremenitev na državnem cestnem omrežjuJamnik, Julijana ...Nosilnost in sposobnost voziščne konstrukcije kot celote, da prevzame prometno obremenitev. Kot merilo nosilnosti voziščne konstrukcije se je uveljavila podajnost (defleksija), ki mora ostati v ... določenih mejah. Nosilnost zagotovimo z izbiro materialov in debelinami plasti, tako da je zagotovljen tolikšen raznos obremenitev, da je podajanje vozne površine v čim večji meri elastično. Pričetek pojavljanja plastičnih posedkov je znak, da voziščna konstrukcija nastopajočih obremenitev ni v stanju prevzemati: bodisi, da se je zaradi zunanjih vplivov zmanjšala deformacijska stabilnost, t.j. odpornost vgrajenih materialov proti preoblikovanju, ali pa je že nastopila faza utrujenosti, t.j. porušitve notranje zgradbe zaradi prevzetih obremenitev. Medtem ko je v času odjuge zaradi zmanjšane nosilnosti podlage najprimernejši ukrep omejitev dopustnih osnih obremenitev, lahko uporabnost obstoječih voznih površin, ki kažejo znake utrujanja, ohranimo oziroma zagotovimo boljšo nosilnost z ojačitvijo. V ekonomskem delu naloge je z upoštevanjem stroškov uporabnikov in stroškov upravljalca cest na konkretnih odsekih preverjeno, ali je bolj ekonomično izvajati obvoze ali z nadgraditvijo ojačati slabo nosilno voziščno konstrukcijo.Source: Zbornik referatovType of material - conference contributionPublish date - 2002Language - slovenianCOBISS.SI-ID - 25207557
