Analiza betona ojačanog vlaknima za betonske kolnike na slabo nosivom tlu ; Analysis of fibre reinforced concrete for road pavements on very weak soils
U ovom su radu analizirani učinci primjene čeličnih vlakana u betonu na debljinu i trošak gradnje betonskog kolnika. Ispitana su fizikalna i mehanička svojstva uzoraka betona ojačanog vlaknima. Rezultati ispitivanja su pokazali da se povećanjem udjela čeličnih vlakana smanjuje obradljivost i tlačna čvrstoća uzoraka, ali se povećava njihova čvrstoća na savijanje i vlačna čvrstoća cijepanjem. Osim toga, prema proračunima metode AASHTO 1993, s povećanjem udjela čeličnih vlakana u betonu, debljina betonskog kolnika smanjuje se od 4,35 % do 18,66 %, a trošak gradnje kolnika povećava se za 56,50 % do 74,07 %. ; In this paper, the effects of steel fibre usage on concrete pavement thickness and cost were investigated. Prepared fibrous concrete specimens were subjected to physical and mechanical tests. From the experiments, it was determined that as the steel fibre ratio increased, the workability and compressive strength of the specimens decreased, but the flexural and splitting tensile strengths increased. In addition, according to calculations made using the AASHTO 1993 design method, the concrete pavement thickness decreased in the range of 4.35 to 18.66 % with an increase in steel fibre, but the pavement cost increased by 56.50 to 74.07 %.
