“…The surface characteristics of SMA mixtures are typically defined by their high macrotexture, and several authors mentioned that their MPD should be greater than 1.0 mm (Kogbara, Masad, Kassem, Scarpas, & Anupam, 2016;Vaiana, Capiluppi, Gallelli, Iuele, & Minani, 2012). In fact, these mixtures use a high amount of coarse aggregates (74%) contributing to an increase in the surface roughness.…”

The reuse of waste materials in asphalt mixtures has been recently investigated, in order to develop new sustainable solutions for the road-paving industry. Such materials should improve the mechanical performance and provide safe/comfortable pavement surface courses for road users, without compromising their environmental performance. Thus, the aim of this study is to evaluate the mechanical, surface and environmental properties of stone mastic asphalt (SMA) mixtures produced with forward-looking asphalt binders incorporating waste materials. These binders were designed to maximise the waste material content using motor oil, high-density polyethylene, styrene-butadiene-styrene and crumb rubber, while performing so well as a commercial modified bitumen. Finally, the overall performance of the SMA mixtures produced with the selected binders was evaluated. It was concluded that these mixtures improve the water sensitivity, fatigue cracking and permanent deformation performance. The requirements for macrotexture, skid resistance and presence of heavy metals in leachates of these mixtures were similarly fulfilled. Thus, this work shows that new asphalt mixtures with waste materials can be used in road-paving works to improve the performance without compromising human and environmental safety.

“…Furthermore, conventional mix plants do not endure for the synthetic zeolite, available in granular form, can be easily added to the mix utilizing an external dosage device. Meager quantities of material (about 0.3% of the total aggregates weight) are used in the mixing process [16]. Zeolite is a group of alumina-silicate fractures that occur in nature with high cation exchange capacity, high adsorption, and hydration-dehydration.…”

“…While [14] states water in the zeolite structure will evaporate if the heating reaches 85°C. Another researcher [16] indicates the use of synthetic zeolite can lower the temperature of making 30°C asphalt mixture lower than hot mix asphalt. Higher temperatures have an adverse effect on water sensitivity.…”

Modifying asphalt aims to improve the performance of the asphalt pavement construction as indicated by increased resistance to permanent deformation and fatigue crack. Asbuton Semi Extraction is one of the materials that can be used for asphalt modification. The addition of Asbuton semi-extraction increases the value of Bitumen Stability Modulus, resistance to permanent deformation and can also increase the asphalt PG value, but require a higher temperature for mixing and compaction. The high temperatures for the manufacture of asphalt mixtures require considerable energy at a more expensive cost and will result in large emissions. The asphalt mixing technology currently being developed is Asphalt Warm Mix, that is asphalt mixture with mixing temperature below 1500°C. One method is to use zeolite additives. The asphalt mixture with the addition of synthetic zeolite can be prepared by mixing and compaction temperatures lower than 30°C of the hot mixture. From the Marshall test, it is known that zeolite addition of 0.3% of the total weight of the mixture gives the characteristic values of the asphalt mixture which still meets the requirements of the specification used. Increased zeolite levels minimize the value of mixed resistance to the immersion indicated by the IRS Marshall value.

“…Pavement surface characteristics change over time and they influence many aspects of tyre-road interaction (Vaiana et al 2012;Praticò et al 2010;Juga et al 2013). It is well known that the vehicle's controllability decreases with speed (Rutka, Sapragonas 2011;Žuraulis et al 2014;Sokolovskij et al 2007;Pečeliūnas, Prentkovskis 2006).…”

Novelty of the research lies in understanding the safety advantages of asphalt made using advanced pavement design process -compact asphalt pavement installation. Variation of tyre-road friction coefficient for this type of pavement design is new and little-studied phenomenon. The present study focuses on the research into tyre-pavement interaction on dry asphalt pavement surfaces to quantify the effect of microprofile on vehicle performance in establishing its braking conditions. The data on a number of different indications (vehicle speed, adhesion coefficients calculated on the basis of braking and friction forces, maximum adhesion coefficient m max and its 'minimum' value m 100% ) and measurement results generated using SRT-4 device for investigation of two road stretches at intervals of 100 m are presented in this paper. The interdependence analysis of statistical variables m max and m 100% has also been presented to exhibit the use of the method. Following statistical parameters are taken into account during random value analysis in order to assess the homogeneity of data: average value, dispersion, standard deviation, confidence interval around a sample mean, and correlation function. Finally, we provide a map between the adhesion coefficient and the longitudinal slip rate for stable and unstable braking conditions of a vehicle.
