“…Use of CNTs as an additive enhances the water resistance of asphalt concrete, heat resistance, cold resistance, shear resistance and increased strength. This property enables increased resistance to aggressive effects of rainfall and wastewater, thus protecting bitumen road surface and preventing premature failure (Vysotskaya and Shekhovtsova, 2015; Urkhanova et al , 2015) (Figure 1).…”

Purpose The purpose of this paper is to study the recent work carried out in enhancing the properties of bitumen using nano-additives. Bitumen is a by-product obtained from the refining process of crude oil, therefore making it a diminishing product. It has been used by mankind since ages for various applications like sealants, binders, waterproof coatings and pavement construction material. It is a black viscous substance with adhesive nature. Design/methodology/approach Bitumen is used as a binding material because of its ability to become liquid when heated and become solid when cooled and thus used largely in construction of roads because of its unique properties. Low softening point of bitumen leads to melting of bitumen during summer and causes rutting of roads, whereas during winter it leads to cracking as bitumen acts brittle in nature during low temperature. Increasing global demand of bitumen has created gap between demand and supply which is increasing with the passage of time. Further modern life has created very high traffic volume and heavy load which makes it essential to improve performance of bitumen. Findings Research studies have reported that the thermal properties of bitumen are enhanced by using thermoplastic polymers such as styrene-butadiene-styrene, polyethylene and ethylene-vinyl acetate, rubber and bio waste etc. Originality/value This paper reviews various types of materials which have been used to improve the properties of bitumen and explores the possibility to synthesise bitumen composite materials with nanoadditives with improved structural, mechanical and thermal properties.

“…Basing on the studies carried out earlier [17][18], where optimal and efficient modes of dispersion and uniform distribution of SWCNT in the volume of the modified binder matrix were selected, based on bitumen BND 60/90, and an optimal concentration range was established in which the effectiveness of CNM introduction into the composition of the PBB, the concentration of SWCNT equal to 2·10 -3 % was adopted.…”

Abstract. Aspects related to plastic track, the formation of which directly depends on the properties of the binder in the composition of asphalt concrete, are considered in this article. The effect of primary carbon nanomaterials on the quality of polymer and bitumen binder in comparison with the traditional binder including cross-linking agent is evaluated. The influence of binders on the resistance to the track formation of type B asphalt concrete is studied. To quantify the service life of surfacing, a calculation method based on the criteria for the resistance of surfacing material to plastic deformations is used.
