Abstract
Zadatak ovog završnog rada obuhvaća ispitivanje dvije mješavine cementom stabiliziranog nosivog sloja kolnika. Ispitana su mehanička svojstva referentne mješavine i mješavine s gumom. Referentna mješavina je sastavljena od prirodnog agregata, 5% cementa i optimalne količine vode, a mješavina s gumom je sastavljena od prirodnog agregata, otpadne gume, 6% cementa i optimalne količine vode. Guma je korištena kao volumna zamjena za pijesak u količini od 30%, a zbog očekivanog smanjenja čvrstoće povećana je količina cementa u ovoj mješavini. Laboratorijska ispitivanja obuhvaćaju određivanje optimalne vlažnosti i maksimalne suhe prostorne mase mješavina, ispitivanje tlačne čvrstoće nakon 7 i 28 dana i ispitivanje otpornosti mješavine na smrzavanje u prisustvu soli. Za izradu uzoraka korištena je metoda vibrirajućeg čekića. Nakon provedenih ispitivanja niti jedna mješavina nije zadovoljila tlačnu čvrstoću za ugradnju u nosivi sloj ceste. Referenta mješavina je razvila preveliku čvrstoću, dok mješavina s gumom nije razvila dovoljnu čvrstoću. Pokazalo se kako je bez obzira na povećanje količine cementa, korištena količina gume više utjecala na smanjenje čvrstoće mješavine. Obje mješavine su ostvarile zadovoljavajuću otpornost na smrzavanje.
Abstract (english)
The task of this undergraduate thesis includes the testing of two cement-stabilized bearing layer mixtures of the pavement. The mechanical properties of the reference mixture and the mixture with waste rubber were tested. The reference mixture is composed of natural aggregate, 5% of cement and optimal water content, and the mixture with rubber is composed of natural aggregate, waste rubber, 6% of cement and an optimal water content. Rubber was used as a volume replacement for sand in the amount of 30%, and due to the expected decrease in strength, the amount of cement in this mixture was increased. Laboratory tests include optimal moisture content and maximum dry density determination, testing of compressive strength after 7 and 28 days, and testing of the mixture's resistance to frost in the presence of salt. The vibrating hammer method was used for specimen preparation. Results of conducted tests showed that none of the mixtures met the compressive strength requirements for installation in the bearing layer of pavement structure. The reference mixture developed too much strength, while the rubberized mixture did not develop sufficient strength. It was shown that, regardless of the increase in the amount of cement, the amount of rubber used had a greater effect on the reduction of the mixture’s strength. Both mixtures achieved satisfactory resistance to frost.
