ABSTRACT / САЖЕТАК:

U radu su prikazane osnovne karakteristike poroznih asfaltnih mešavina. Posebno su obrađene prednosti njihove primene koje se ogledaju u povoljnim uticajima vezanim za bezbednost odvijanja saobraćaja, uslove vožnje i smanjenje štetnog uticaja na okolinu, prevashodno kroz poboljšanje kvaliteta vode i smanjenje saobraćajne buke. Objašnjeni su koncepti projektovanja i ispitivanja ovih mešavina i prikazano je projektovanje asfaltne mešavine od poroznog asfalta PA 11 za potrebe izrade habajućeg sloja kolovozne konstrukcije u infleksionim zonama autoputeva. Za mešavinu je korišćen kameni agregat eruptivnog porekla Mrčići, Divčibare, kameno brašno Bekament, polimer modifikovani bitumen PmB 45/80-65 i vlakna Viatop. Za poboljšanje veze bitumena i agregata korišćeni su hidratisani kreč i hemijski aditiv Iterlene. Ispitivanjem mešavina dobijeni su zadovoljavajući rezultati i u pogledu dreniranja veziva i u pogledu gubitka materijala.
