“…), material heterogeneity (RAP Asphalt Content & Gradation) and other sources of variations caused RAP variability [23][24][25][26][27][28]. Despite this, it is noted that due to the use of a very high percentage of RAP, experiments demonstrate that the solutions proposed meet a number of sustainability requirements [29][30][31]. Furthermore, these facts illustrate the potential and suitability of the designed mixes for improved pavement life cycles [32][33][34][35].…”

The goal of this paper is to investigate transportation infrastructure sustainability from a wider standpoint.A sustainable transportation infrastructure can be defined as a safe, efficient, economic, environmentally friendly infrastructure meeting the needs of presentday users without compromising those of future generations. This concept involves environmental, economic and societal aspects.In more detail, as for a road, a sustainable infrastructure or pavement must comply with environmental, economic and social requirements.Unfortunately, even if a definition of a sustainable pavement for urban or suburban areas can be easily proposed, the proposal of practical strategies to really pursue sustainability goals is sometimes disregarded in favour of emphatic announces of not well defined sustainable solutions.In the light of the above facts, the sustainability of a transportation infrastructure based on the actual environmental, social and economic characteristics is discussed in this paper. Once the main factors which can influence infrastructure sustainability are assessed, an analysis is performed in order to set out practical strategies for pursuing the main objective.Finally an experimental investigation is designed and carried out in order to assess porous asphalt value in terms of pavement sustainability. The tests carried out are promising about the possibility of achieving suitable levels of overall performance. Practical applications and perspectives in rehabilitation, maintenance, and research are outlined.

“…In addition, the water resistance and stiffness of mixtures with waste materials is higher compared to similar values for the control mixture. Chen et al [36] conducted X-ray testing in laboratory conditions. They analysed the possibility of using recycled concrete dust by means of scanning electron microscopy and x-ray fluorescence spectroscopy.…”

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.

Evaluation of Mechanical Properties of Recycled Material for Utilization in Asphalt Mixtures

et al. 2017

Abstract:With an expanding world, the demand for extensive road networks is increasing. As natural resources become scarce, the necessity of finding alternative resources has led to the idea of applying recycled material to pavement construction including asphalt pavements. Amongst all asphalt components, aggregate constitutes the largest part of asphalt mixtures. Therefore, the utilization of recycled material for aggregate will represent an important opportunity to save virgin material and divert material away from landfills. Because of the large amount of construction waste generation around the world, using recycled construction aggregate (RCA) in asphalt mixtures appears to be an effective utilization of RCA. However, as aggregate plays an important role in the final performance of the asphalt mixture, an understanding of their properties is essential in designing an asphalt mixture. Therefore, in this research, the properties of RCA have been evaluated through laboratory investigations. Based on the test results, it is required that combination of RCA with some other targeted waste materials be considered in asphalt mixture. This paper presents the results of an experimental study to evaluate the RCA properties as an alternative for virgin aggregate in asphalt mixture under different percentages and combination with other aggregates, such as reclaimed asphalt pavement (RAP) and basalt.
