The purpose of this research is to observe the strength of asphalt concrete using solidified coal waste or geopolymer. The use of geopolymer is known in enhancing concrete mixture strength. More detail in this study is to acquire the comparison rate of stability and flow of mixture using geopolymer and the one with ordinary filler. The stability and melting rate of this mixture will determine whether the use of geopolymer as a filler material in flexible pavement is applicable. In this research, the first stage is to find the initial mix design, which is not including the geopolymer filler. From this research, it is found that the use of geopolymer increases the stability in asphalt mixture but reduce the melting rate and increase the cavity in the mixture. Although the melting rate decreases and the voids increases, the result acquired still fulfills the minimum specification of asphalt concrete for the high level of traffic load.

Marshall Stability

Stability is a measure of the strength of an asphalt mixture in resisting deformation due to loading. If a road construction structure cannot withstand the existing load, it will result in road damage that endangers road users. This study aims to improve the stability of the asphalt concrete mixture with the use of crumb rubber. Crumb rubber is used because it has good resistance and elasticity. The research was conducted experimentally by making test objects in the laboratory. In this study, five variations crumb rubber (2%, 4%, 6%, 8%, and 10% of the weight asphalt mixture) were carried out with the size of the powder retained on a 40 sieve. Marshall test and analysis of volumetric was carried out to determine the characteristics of the asphalt-concrete mixture. The results showed that the highest Marshall stability was obtained at 10% crumb rubber with a stability value of 1422 kg. The use of rubber powder can significantly increase the strength and quality of the asphalt-concrete mixture. Thus, crumb rubber can be used, and this percentage can be used as a reference in the manufacture of asphalt-concrete mixtures in order to obtain good road pavement quality.

Abstract. Problem. The temperature of mastic as-phalts mixing is significantly higher than the one for hot asphalt mixtures. It is due using of high viscous bitumens as a mixture component and realizing the main advantage of mastic asphalt – its ability to flow and compact with its own weight at high tempera-ture. There is no uniform way to assign the process temperatures for mastic asphalt. Goal. To find the process temperatures for mastic asphalt with bitumen binders differ by viscosity as a researching on tem-perature influence and influence of binder concentra-tion on properties of mastic asphalt is a goal of this research work. Methodology. The mastic asphalt mixtures and asphalt concrete with conventional pavement bitumen 70/100 (penetration is 85 dmm) and high viscous bitumen (penetration is 38 dmm) are chosen for research. The mineral aggregates contain 42 % of crushed granite 5-10 mm, 33 % of granite screening and 33 % of limestone powder. The properties of mastic asphalts are evaluated with EN 12697-20:2003, SOU 42.1-37641918-106:2013 and DSTU EN 13108-6:2018. Results. It was found a significant influence of amount and viscosity of bitu-men and a temperature on workability of mastic as-phalt mixture and on properties of mastic asphalt concrete. Originality. The comparative analysis of workability of mastic asphalt mixture and properties of mastic asphalt concrete with bitumens differ in viscosity is a scientific originality of presented re-search. Practical value. Due to research results it is not reasonable to assign the temperature that sup-plies viscosity of 0.5 Pa•s as a temperature of mixing of mastic asphalt. The temperature conditions of mastic asphalt mixing are much higher (200 – 240 °C). To evaluate workability and find a minimal acceptable temperature of mixture it is possible to use the thickness of the mixture layer after spreading as an indicator. With this the acceptable workability of the mastic asphalt mixture can be characterized by thickness of its layer 30 mm or less after spreading.

Риск и неопределённость онтологически присутствуют в жизненном цикле людей, и поэтому эти проблемы всегда актуальны, особенно в современном социуме постмодерна. Информационное постиндустриальное общество характеризуется большим объёмом разнообразной информации, легко доступной для всех членов социума. С одной стороны, доступ к информации и её количество представляют собой благо, с другой стороны, люди не могут адекватно выбрать, интерпретировать и оценить новые сведения. Возникающая в этом случае неопределённость дезориентирует людей, нарушая стабильность их социокультурных коммуникативных связей. Неопределённость амбивалентна по своей природе - она субъективна как проекция личностного восприятия социальной реальности; она объективна как актуализация слома/смены социальных смыслов и институтов. Исследование о природе неопределённости и рисков едины в том, что высокий уровень неопределённости современности обусловлен такими факторами, как глобализация, информатизация и цифровизация. «Текучая современность» как социальная реальность характеризует сегодняшнюю жизнь людей в ракурсе основных концептов жизнедеятельности: свободы, индивидуальности, времени и пространства, работы и сообществ. Концепция рисков как продуктов неопределённости варьируется - от сравнения рисков с аварией на Чернобыльской АЭС до оценки рисков как мобилизующих сил. Социокультурные риски, межкультурные в частности, приобретают особую значимость в эпоху постмодерна. Выделенные 6 универсальных категорий культуры определяют межкультурную интеракцию в ракурсе учёта культурных характеристик, детерминирующих успех межкультурного взаимодействия. Теория сокращения неопределённости предлагает пути установления успешной межкультурной коммуникации. Обозначены стратегии смягчения неопределённости (пассивные, активные и интерактивные), и факторы её успеха обусловлены уровнем межкультурной компетенции коммуникантов. Следование принципам Кооперации и Вежливости способствует снижению межкультурной неопределённости и рисков как видов коммуникативного дискомфорта. Risk and uncertainty are ontologically linked with the life cycle of people, and therefore these problems are always relevant, especially in the contemporary postmodern society. The informational postindustrial society is characterized by a large amount of diverse information that is easily accessible to all members of society. On the one hand, access to information and its amount is a real value, on the other hand, people cannot adequately select, interpret and evaluate new information. The uncertainty arising in this case disorients people, disrupting the stability of their socio-cultural communicative ties. Uncertainty is ambivalent in nature - it is subjective as a projection of personal perception of social reality; it is objective as an actualization of the breakdown/change of social meanings and institutions. The study on the nature of uncertainty and risks is unanimous in the fact that the high level of uncertainty of our time is due to such factors as globalization, informatization and digitalization. “Fluid modernity” as a social reality characterizes everyday life of people from the perspective of the main concepts of life: freedom, individuality, time and space, work and communities. The concept of risks as products of uncertainty ranges from comparing risks with the Chernobyl accident to assessing risks as mobilizing forces. Socio-cultural risks, intercultural in particular, acquire special significance in the postmodern era. The identified 6 universal categories of culture define intercultural interaction from the perspective of taking into account cultural characteristics that determine the success of intercultural interaction. Uncertainty reduction theory offers ways to establish successful intercultural communication. The identified strategies for reducing uncertainty (passive, active and interactive) and the factors of its success are determined by the level of intercultural competence of the communicants. In addition, adherence to the principles of Cooperation and Politeness helps to reduce intercultural uncertainty and risks as types of communicative discomfort.

Nowadays, road damage issue become the norm due to increment of traffic load and traffic volume. It shortens the service life of asphalt mixtures and increase the cost of maintenance. One way to reduce the issue is by using polymer additive in asphalt mixture. Treated Plastic is one type of polymer additive made of plastic bag (Polyethylene). The main purpose of this research is to determine the improvement of asphalt mixture’s performance incorporating Treated Plastic (TP) as additive in terms of stability, stiffness, fatigue cracking, stripping and rutting. The mechanical properties of asphalt mixes that include various percentages of TP (0%, 0.25%, 0.5%, 0.75%, 1%, 2% and 3%) were calculated and assessed with laboratory tests. 0.75% by weight of total mix of TP was found to be the optimum amount. The outcomes were analyzed by Marshall Stability and Flow, Resilient Modulus, Tensile Strength Ratio and Hamburg Wheel Tracker test. As the results shown, the addition of TP gave significant improvement to the stability and stiffness of asphalt mixture. 0.75% of TP was selected as the optimum percent content with percent improvement about 100, 73 and 25% for fatigue cracking, rutting and stripping resistance respectively. Hence, 0.75% of TP improved the resistance of rutting and stripping but susceptible to fatigue cracking.
