Influence of recycled filler on asphalt mix properties

Abstract

An overview of research conducted so far on the use of various recycled materials as replacement for stone filler in asphalt mixes is presented in the paper. The paper comprises an overview of research on the influence exerted by the waste glass, waste materials from cement industry, concrete, brick, ceramics, fly ash and other materials, on physicomechanical properties of bitumen mixes. As a final result, conclusions are given on the possible use of individual recycled materials as replacements for standard rock flour in asphalt mixes. Utjecaj recikliranog punila na svojstva asfaltnih mješavina U radu se daje prikaz provedenih dosadašnjih istraživanja s primjenom različitih recikliranih materijala koji se koriste kao zamjena za kameno punilo u asfaltnim mješavinama. Rad obuhvaća prikaz provedenih istraživanja o utjecaju otpadnog stakla, otpada cementne industrije, betona, opeke, keramike, letećeg pepela i drugih na fizikalno mehanička svojstva bitumenskih mješavina. Kao konačan rezultat donose se zaključci o mogućoj primjeni pojedinih recikliranih materijala kao zamjeni za standardno kameno brašno u asfaltnim mješavinama.

Laboratory Evaluation of the Properties of Asphalt Mixture with Wood Ash Filler

“…Fly ash made by the combustion of coal in thermal power plants found their application in asphalt mixtures first [23][24][25][26]. Various applications of this type of ash were the most and longest researched.…”

Investigation of textile waste usage in stone mastic asphalt (SMA) mixtures

“…Therefore, the design of highway networks that requires large capital expenditures is very important [1,2]. A satisfactory pavement design should be sufficiently serviceable, durable, resistant to permanent deformation, economical, and eco-friendly [3][4][5]. On a global scale, flexible pavements are the preferred type of highway superstructure [6][7][8].…”

Rheological characteristics of bitumens prepared with process oil

“…The comfort and durability parameters that asphalt pavements can provide over the service life depend on the properties of bitumen used in asphalt mixtures [9,10]. The utilization of additives in bitumen improves stiffness properties at high temperatures, and resistance against moisture and cracking at low temperatures [11][12][13]. This has encouraged researchers and engineers to investigate the effective and environmentally friendly additives for bitumen modification, aimed at improving performance characteristics of bitumen [12].…”
