RAZVOJ MODELA PERFORMANSI FLEKSIBILNE BETONSKE KOLOVOZNE KONSTRUKCIJE U NIGERIJI
Journal Title: INTERNATIONAL JOURNAL FOR TRAFFIC AND TRANSPORT ENGINEERING - Year 2012, Vol 2, Issue 3
Abstract
U radu su predstavljeni rezultati studije sprovedene u cilju razvoja modela performansi betonske kolovozne konstrukcije, koji su karakteristični za Nigeriju i slične zemlje u razvoju i kojima je moguće predvideti stopu pogoršanja u toku eksploatacionog veka kolovozne konstrukcije. Detaljna istraživanja su sprovedena na jednoj od najopterećenijih saobraćajnica u državi, autoputu koji povezuje Lagos (ekonomski centar Nigerije) i Ibadan (najveći grad Zapadne Afrike). Prikupljeni su podaci koji se odnose na karakteristike saobraćaja, ocenu stanja kolovoza, vrste oštećenja, debljinu kolovozne konstrukcije, indeks hrapavosti, padavine i temperaturu. Razvijeni su modeli za određivanje ocene stanje kolovoza (PCS) i međunarodog indeksa hrapavosti (IRI). Za analizu podataka i ocenu uticaja ključnih ulaznih parametara na PCS i IRI, primenjena je multipla regresiona analiza. Utvrđeno je da su za određivanje PCS statistički značajni parametri poput dubine kolotraga i površine udarnih rupa, dok su broj zakrpa, dužine longitudinalnih pukotina i dubine kolotraga značajani za predviđanje IRI. Razvijene modele je moguće koristiti za planiranje programa održavanja puteva čime se minimizira skup i dugotrajan proces prikupljanja podataka o stanju kolovozne konstrukcije pre održavanja.
