The TG3 aimed to evaluate the effect of a specific family of materials known as asphalt recycling agent (ARA) on the a...

The use of rejuvenators has seen a consistent increase over the years in the asphalt pavement industry. This is due to the need for maximizing the demand for incorporating a higher amount of Reclaimed Asphalt (RA) in the pavement asphalt mixtures. In order to tackle this challenge, the Task Group 3, focusing on asphalt binders and additives, of the...

The use of Reclaimed Asphalt (RA) into new asphalt mixtures becomes an inevitable step for sustainable infrastructure. Saving natural, non-renewable materials, such as bitumen and aggregates, the asphalt industry is moving forward with more recycling. Although asphalt is a 100% reusable material, high recycling rates are not yet easily achievable d...

In view of increasing social and environmental consciousness, a circular approach in waste materials management in order to convert them into new secondary resources is becoming more necessary. Given this context, an interlaboratory testing program (ILTP) focusing on maximizing the use of waste aggregates replacing conventional virgin ones has been...

The use of Reclaimed Asphalt (RA) into new asphalt mixtures becomes an inevitable step for sustainable infrastructure.

The paper analyzes the performance of polymer modified bitumen due to multiple stress creep recovery (MSCR). This phenomenon is of great importance when considering binder’s performance related to rutting resistance on high temperatures during exploitation period. The paper presents testing results of five polymer modified bitumen samples, obtained...

The growing use of reclaimed asphalt (RAP) results in a continuous increase in the percentage of added RAP to hot mix asphalt. Within the asphalt pavement, the asphalt binder is the component which is affected the most by the ageing during service life, resulting in considerable hardening of the RAP binder. Therefore, the aged binder needs to be re...

The need for road (re)construction materials is constantly growing. At the same time, there is a limited quantity of new, high-quality materials available and a buildup of secondary/recycled construction materials. One possible solution may be the use of recycled concrete aggregate (RCA) in asphalt mixtures instead of natural aggregate (NA), which...

The lack of understanding the mechanisms governing the interaction between reclaimed asphalt binder (RAb)1 and recycling agents is one of the technical issues that still need to be resolved when high amount of reclaimed asphalt (RA)2 is used in a new recycled asphalt mixture (RAM). Due to important role of RAb in that interaction and increased used...

Road quality has an important role for the smooth traffic flow. Asphalt concrete layers are the most significant elements of roads; but due to their position, they are exposed to the influence of many external factors (water, sun, freeze, fuel) which affect their lifespan. At the same time, limited quantities of new materials are forcing investors...

Recently, the reduction of the environmental burdens related to highway infrastructures has been in the spotlight. Within this context, the use of recycled materials in bituminous mixtures for road pavement construction and maintenance has the potential to mitigate the excessive use of non-renewable resources. Nevertheless, the material consumption...

It is common practice to assume full blending of the aged binder of reclaimed asphalt (RA) within the design of new asphalt mixtures. Although being practical, this assumption has often led designers to asphalt mixtures lacking binder. Hence, going towards recycled asphalt mixtures (RAM) there is a need to have a better understanding of the blendin...

Флексибилне коловозне конструкције су подложне појави пукотина услед замора и термичких утицаја, а значајан проблем представља и појава рефлектованих пукотина код полукрутих коловозних конструкција или код крутих које су пресвучене слојевима асфалта. Армирањем асфалтних слојева применом геомрежа, могуће је значајно успорити, ако не и спречити појав...

Brz industrijski razvoj tokom poslednjih decenija doveo je do stvaranja raznovrsnog industrijskog otpada koji nameće ozbiljne ekološke probleme. U više navrata su vršeni pokušaji da se poveća ponovna upotreba otpadnih i alternativnih materijala za izgradnju građevinskih objekata. Jedan od tih materijala je i bakarna zgura koja nastaje topljenjem i...

The use of high Reclaimed Asphalt Pavement (RAP) content in Hot Mix Asphalt (HMA) allows developing innovative materials for the construction and/or rehabilitation of sustainable infra-structures.

Porous asphalts are applied all over the world to minimize the effect of noise caused by everyday traffic. Beside the effect of noise reduction, thanks to their open texture and improved drainage characteristics, porous asphalts decrease the impact of spraying water behind a moving vehicle. Since drainage capability of porous asphalt as a surface p...

Recycled concrete aggregate (RCA), obtained by crushing of original (old) concrete, consists of natural aggregate grains and a cement mortar matrix. The presence of old adhered cement mortar, which has higher porosity than natural aggregate, causes unfavourable properties of RCA. In this paper, the research conducted in order to improve the quality...

Production of asphalt mixture on asphalt plants includes a series of procedures, ranging from stockpiling, through a mix design, methods of production, to quality control. If RAP1 is added to the mixture, it should pay more attention to certain procedures related to production, one of which is way of the handling RAP. One of the goals of its use is...

Exposure to the noise, which is higher than the acceptable level, can lead to negative effects on human health. Therefore, it is necessary to avoid, prevent or reduce the adverse impact of noise. It is a long lasting process that involves the adoption of technical regulations, setting obligatory limits, prescribing measures, as well as their execut...

On the basis of a large number of previous research, strong relationship between the characteristics of the surface course of pavement, mostly macrotexture and microtexture, and friction was established. Roughening of texture in new pavement design leads to increasing of pavement friction, although it can reduce a ride comfort at the same time. Fla...

The addition of reclaimed asphalt pavement (RAP) to asphalt mixtures, although widely used in many countries, is still in the beginning stage in Serbia. According to many studies, RAP rates between 10% and 20% are commonly used in asphalt mixes and they perform similarly to conventional mixtures. The use of higher RAP rates, up to 50 %, would lead...

The use of recycled asphalt pavement (RAP) in new mixtures has become a priority in many countries around the world, especially in countries which have a problem with the lack of new, virgin material (aggregate and bitumen). In Serbia is no trend to use increased quantities of old asphalt in new asphalt mixtures. RAP was used in some sections in Se...
