“…For modification of road bitumens, thermoplasts are most commonly used (mainly, SBS-type styrenic block-copolymers) owing to their capability not only to increase the bitumen strength, but also impart elasticity to a polymer bituminous mixture, specifically at lower temperatures, and also increase adhesion of bitumen with a mineral material. The content of such polymers in modified bitumens may account for 3-10 wt % [1][2][3][4][5].…”

1 The effect of factors on the process of obtaining phenol-cresol-formaldehyde resin (PhCR-F) has been studied. By using empirical evidence, the adequate experimental statistical-mathematical (ESM) model has been developed. Based on this model, the optimal values of the process factors for obtaining PhCR-F have been identified, bringing about both high yield and softening point of the resin. Data predicted on the basis of the ESM model were compared with empirical evidence about PhCR-F preparation.Анотація.

Activities aimed at the improvement of instruments of rural development have been undertaken in Europe for many years. Those focusing on the changing the ownership structure, implemented through the traditional process of land consolidation, are gradually replaced by multifunctional activities for rural development, considering elements of environmental protection, agricultural landscape management, and solutions concerning soil and water protection. Such development must be accompanied by the application of new pro-ecological design and material-technological solutions regarding the construction of rural roads. The roads should be designed with possibly the fullest consideration of a rich resource of data on a given area, performance of many spatial analyses, and decision making in the scope of selection of the most appropriate solutions acceptable to all stakeholders (e.g. residents, farmers, local authorities, entrepreneurs, and investors). The article presents the concept of a model solution of the development of the rural road network based on the multiple-criteria model of spatial analyses with the application of the Analytic Hierarchy Process method. The research process was conducted in the geographic information systems environment. The importance of the proposed methodology was verified in actual conditions based on the example of the Harta village located in the southern part of Poland. The obtained results suggest that the process of development of rural roads with the application of the multiple-criteria model of spatial analyses is more accurate, more efficient than the traditional design method, and considers the requirements of the sustainable development of rural areas. Moreover, it permits presentation of solutions in the form of maps to the local community, almost in real time, and making excellent decisions with its active participation.

“…The role of using bio-asphalt in new asphalt mixtures is currently considered as one of the main alternatives for the reduction of environmental and health effect, the final cost of hotmix asphalt (HMA) pavement construction, and minimize strong demand of conventional asphalt binder [1][2][3][4][5][6][7][8][9][10]. Some of these bio-binders studied and showed promising results include: sugar cane molasses [11][12][13][14], beet molasses 15 , swine manure 1,[16][17][18] , waste cooking oil [6], [19][20][21], and wood waste 22,23 .…”

The high volume of water in molasses has made this study serious. The reason is that using molasses as a partial replacement without treatment significantly affects the rheological properties of the neat bitumen and increases the likelihood of moisture susceptibility of the hotmix asphalt (HMA) pavement structure and create fractures of aggregate particles. Therefore, to use molasses as a partial replacement without affecting the structural integrity of the pavement, this study proposed a treatment method before blending it with petroleum-based bitumen. A series of experiment was conducted to accomplish the objective of this paper, including convectional tests, Fourier transform infrared (FTIR) test, amplitude and frequency sweep test, performance grade (PG) determination test, and multiple stress creep recovery (MSCR) tests. The IR spectra show that carbonyl index decreased with increasing molasses percent. There was PG improvement from the control grade to PG64 and PG70 when the base binder modified with 5-20% molasses and aged with rollingl thin film oven (RTFO) respectively. At the temperature 58 o C nonrecoverable creep compliance at 3.2 kPa (Jnr3.2kPa) was decreased for each percent replacement. This led to improving the rutting potential. As well, at a temperature of 64 o C the Jnr value was decreased only for 5% replacement, and then the Jnr value was gradually increased for the remaining percent replacement. Overall, this study revealed that treated molasses can be used as a partial replacement to enhance the rheological properties of the base bitumen and thus it can potentially be used to produce a sustainable bio-asphalt binder.
