“…This was reflected in the values of the colloidal stability index (GI), which were 0.31 in the case of bitumen 160/220 and 0.48 in the case of bitumen 50/70. Based on the literature review, the value of GI = 0.36 is considered the limit value [ 4 , 8 ]. Bitumens of GI < 0.36 feature good compatibility with polymer-based modifiers.…”

The article deals with the issue of determination of the content of SBS (Styrene-Butadiene-Styrene) in polymer-modified bitumens (PMBs). The effect of SBS copolymer on the physical and rheological properties of bitumens has been thoroughly investigated and widely described in the literature. Condition surveys of structures and evaluation of the properties of materials used at construction sites have become a huge challenge for construction engineering. Determination of the content of SBS modifier in various building materials (asphalt mixtures and bituminous waterproofing compounds) is a good example in this respect. Based on the laboratory tests, mid-infrared spectroscopy was found to be the most effective analytical method. It can be used for easy detection of the presence of SBS in a modified bitumen. However, quantitative analysis is an issue that calls for research. Currently, there are no standard guidelines, whether national or European, that would regulate the method of testing. Three test methods were assessed in this study: the AASHTO T302–15 standard method and two Australian methods described in codes of practice (T521 and Q350) developed by the local authorities, which define a standard way of determining the amount of SBS in polymer-modified bitumens. The tests were carried out on standard controls and samples sourced from the industry. The above-mentioned test methods were assessed in terms of accuracy of determination, reliability of results obtained on the industrial samples, level of complexity of the test procedure, sample preparation techniques and the type of the required reagents.

“…Despite the favorable features of highly modified asphalts [18], which were recognized over a decade ago, taking into account the impact of their parameters on the design life of the structure still proves challenging. Although the results of laboratory fatigue tests of asphalt mixtures with HiMA binders indicate durability that is many times greater than in the case of unmodified asphalt mixtures [2,19], the fact that the standard formulas used to calculate the fatigue life of the pavement do not enable direct evaluation of the benefits of using highly modified binders with SBS polymers (lower layer stiffness and higher critical structure strain vs. higher fatigue resistance of the asphalt mixture) is still problematic. Determination of the fatigue life of pavement layer systems that include HiMA asphalt layers poses significant difficulties due to the fact that the literature still lacks sufficiently accurate, reliable and relatively simple tools to quantify the fatigue life and, more broadly, the durability of such pavements [20].…”

“…The values of material parameters of the H-S model of asphalt layers were assumed for the equivalent temperature of T = 10 • C (for the entire year) and for frequency f = 10 Hz (corresponding to the typical speed of heavy vehicle traffic, estimated as 60-75 km/h under free flow traffic conditions). These values, determined from the master curves on the basis of measurements of complex stiffness moduli E* for a specific set of frequencies f from the four-point bending of samples according to the standard [41], were taken from the work [19].…”

“…Similarly, at low temperatures, due to the lower stiffness of the binder, cracking occurs later Materials 2021, 14, 480 2 of 14 than in mixtures with standard (unmodified) binders. This has been proven by the results of fatigue testing of asphalt mixtures using the 4PB-PR, TSRST and SCB methods [13,14], but also by the results obtained in the bending beam rheometer BBR [15] and in the LAS test [16,17].…”

Since 2009, SBS (styrene-butadiene-styrene) polymer-modified binders (HiMA—Highly Modified Asphalt) have been tested worldwide. Highly modified binders are characterized by extraordinary properties resulting from the reversal of the binder-polymer phase. This contributes to very good test results for asphalt mixes. The use of such a modern binder poses a challenge in terms of structure design, mainly due to the lack of a recognized and calibrated method suitable for this material. The article proposes a new approach to pavement fatigue life estimation—the Similarity Method—which is based on the use of AASHTO 2004 equations and laboratory fatigue testing results of asphalt concrete mixes for asphalt base course. The article presents the method and the results of its sensitivity testing with respect to the influence of the material (type of asphalt concrete), thickness of the asphalt base course, stiffness of the subgrade and the assumed FC index (the area of bottom-up cracks). The results of fatigue life according to the Similarity Method are within the range of values obtained for AASHTO 2004 and the fatigue results according to the equations obtained in the laboratory. This approach will enable inclusion of new materials, such as HiMA asphalt mixtures, in pavement structure design.
