“…The highest R 2 values determined for the aromatics and resins at the frequency of 1.29 Hz, in the case of the elastic part of the complex modulus, have a different course at other frequencies. The R 2 values for the resins increase for the lower frequencies and decrease for the frequencies higher than 1.29 Hz. However, the change of the R 2 values for the aromatics is opposite (the lower values for the lower frequencies and vice versa).…”

The quality of bituminous binders is commonly evaluated by the empirical tests. The functional approach to the evaluation of bitumen properties is a trend that has been applied in the last years. The dynamic shear rheometer (DSR) test has been widely used to determine the shear complex modulus of bitumen in the wide range of frequencies and temperatures. A lot of research works were focused on the effect of the chemical compounds of bitumen on the values of the shear complex modulus. The missing information related to the effect of the compound of bitumen on the elastic and plastic part of the shear complex modulus was input for the presented investigation. The significant effect on the elastic part of the complex modulus was determined only at the high temperatures (60 and 80 °C). The aromatics, resins and asphaltenes were identified as the influencing compounds. The important effect was also noted for the resins at the temperatures of 5 and 15 °C. It was also concluded that the effect of the saturates on the elastic part of the shear complex modulus is marginal. The effect of the aromatics and asphaltenes on the plastic part of the shear complex modulus was identified only at the temperature of 80 °C. The effect of these two compounds at other temperatures seems to be unimportant. The significant effect of the resins was stated for the temperatures of 15 °C and 5 °C. Their effect at other temperatures can be supposed as marginal. The negligible effect of the saturates on the plastic part of the shear complex modulus was deducted.The regression analysis of the chemical composition of the bitumen and the parts of the shear complex modulus at the temperature of 80 °C proved that the frequency of the DSR test can be a factor affecting the level of the relationship between the group composition of the bitumen and its rheological properties.

“…Additional recycled asphalt pavement (RAP) or recycled roofing shingle (RAS) can improve the rut resistance of WMA mixture but weaken the fatigue life of these WMA mixtures [6,23,24]. In addition, some studied reported that as the WMA mixtures are thermally aged, the moisture resistance of the mixtures can be obviously improved [26,26]. The WMA binders having similar or better rheological properties at high performance temperature before or after a thermal aging process or UV aging process were reported by some researchers recently [6,13,18].…”

“…Using various recycling methods of these building materials, it is possible to maintain the natural material resources (aggregates and bitumen) and decrease the energy and economical demands of construction works. Given the fact that the cost of basic components for the manufacture of asphalt mixtures constantly increases in long term, the use of reclaimed asphalt (RA) in asphalt mixture manufacturing is advantageous from the economical perspective as well [4,5]. It is not just the cost of the aggregate but also the cost of the bitumen, which is the most expensive component in the asphalt mixture.…”

e paper focuses on the issue of using reclaimed asphalt (RA) in asphalt mixtures used for highly traffic-loaded asphalt pavements-in asphalt mixtures of the stone mastic asphalt (SMA) type. It is a skeleton-type mixture, where the traffic load is bore by a skeleton of coarse aggregates bonded with mastic (i.e., bitumen and fine aggregates). It is therefore essential to pay close attention to the properties of this coarse aggregate. Higher demands on properties of the aggregate are probably due to the fact that RA is not currently being used in SMA-type mixtures. Most standards do not allow usage of RA in this type of mixtures. Given that traffic load of road networks is constantly increasing, the ratio of SMA-type asphalt mixtures also increases in the road network.is paper presents results of 5-year research focused on the possibility of using RA in SMA-type asphalt mixtures. is included laboratory design of these mixtures with various dosages and types of RA. eir empirical and functional properties were verified. Based on the positive results of the laboratory testing, a test section was subsequently constructed using several variants of the mixtures containing up to 50% of RA. is test section is regularly being monitored, and despite very intense traffic load, there are no failures apparent after 2 and half years of operation. Based on the laboratory research and subsequent construction and monitoring of a test section, it can be said that RA can be used in SMA-type mixtures without any negative impacts on functional properties or mixture lifetime.
