“…Since the primary modes of failure in asphalt concrete pavements are low-temperature cracking, intermediate-temperature cracking, and rutting at higher temperature, performance grading attempts to cover the properties of the whole working temperature range of bitumen. For example, bitumen PG 64–10 sees the performance criteria at an average seven-day maximum pavement temperature of 64 °C and at a minimum pavement temperature of −10 °C. , …”

Petroleum refineries are one of the largest greenhouse gas (GHG)emitting industrial sectors. One of the ways by which refineries can reduce emissions is by reducing the consumption of utilities (heat and steam) required in the refineries or by increasing the throughput of the refinery. Process intensification is one way by which throughput can be increased, and also process heat requirements can be reduced. Cavitation-driven process intensification has created many opportunities in the field of nanoparticle synthesis, wastewater treatment, water disinfection, crystallization, depolymerization, extraction, and emulsification. In recent years, cavitation-assisted bitumen processing has been explored in petroleum refineries. The present Review focuses on the studies related to cavitationally driven transformations in bitumen processing. Case studies have been critically reviewed in various aspects related to the use of cavitation in bitumen recovery from sands, bitumen viscosity reduction, bitumen desulfurization, improving compatibility of rubberized bitumen, bitumen nanoemulsion, and bitumen wastewater treatment. The present Review would be a ready reckoner highlighting the relative advantages and the current status of cavitation-assisted applications of bitumen. This Review also highlights the research gap and proposes future work in the area of cavitation technology for bitumen processing.

With sustainability being the most crucial issue of recent years, the use of waste materials in bitumen modification is increasing and becoming widespread. In this experimental study, it was aimed to investigate the high- and low-temperature behavior of bitumen samples modified with waste cooking oil (WCO), reactive ethylene terpolymer (RET), and polyphosphoric acid (PPA). Accordingly, the multiple stress creep and recovery (MSCR) test and the bending beam rheometer (BBR) test were conducted. Depending on the increasing WCO ratio, the Jnr,R%,∆T_c,and λ parameters of modified bitumens were examined in detail. It was observed that with increasing WCO ratio,the Jnr value increased, and elastic recovery and stiffness decreased. In addition, it has been determined that this composite-modified bitumen is resistant to heavy traffic loads and has sufficient flexibility at low temperatures.

“…No entanto, posteriormente, constatou-se que esse parâmetro apresenta muitas limitações na avaliação do dano real dos ligantes asfálticos, pois não se relaciona bem com o acúmulo de danos por fadiga das misturas asfálticas (DEACON et al, 1997;BAHIA et al, 2001) Diferentes estudos vêm incorporando análises entre o comportamento reológico dos ligantes e seu efeito no desempenho das misturas asfálticas (BARROS et al, 2022;ZEIADA et al, 2022;OGBO et al, 2019;GOOSEN;JENKINS, 2023) Com a constante preposição de novos indicadores da resistência à fadiga do ligante asfáltico, e consequentemente a resposta a esse fenômeno na mistura asfáltica, este estudo avalia a correlação de índices reológicos de ligantes não modificados e modificados por polímeros com resultados do comportamento à fadiga de misturas.…”

O fenômeno da fadiga em pavimentos asfálticos refere-se à deterioração progressiva devido ao acúmulo de danos causados pelas cargas cíclicas do tráfego de veículos e do clima. No Brasil, os pavimentos são predominantemente flexíveis, sujeitos a desafios de aumento de carga do tráfego e variações de temperatura. O projeto do National Cooperative Highway Research Program (NCHRP 09-59) propôs melhorias nas avaliações da resposta à fadiga do ligante, como a consideração dos parâmetros Glover-Rowe (GRP) e R. Pesquisadores têm correlacionado o comportamento reológico dos ligantes com o desempenho das misturas asfálticas. O presente estudo avalia e correlaciona índices reológicos de ligantes não modificados e modificados por polímeros com o comportamento à fadiga das misturas. Foram preparadas oito misturas asfálticas com diferentes ligantes e agregados. Os ligantes foram caracterizados reologicamente com o reômetro de cisalhamento dinâmico (DSR) no domínio de linearidade do comportamento viscoelástico e também pelo ensaio Linear Amplitude Sweep (LAS). As misturas foram avaliadas por ensaios de módulo dinâmico e de fadiga por tração direta uniaxial. Os resultados mostraram correlações entre os índices reológicos dos ligantes (parâmetros GR, R, ?Tc e |G*|.send, este último da especificação AASHTO M320) e o desempenho à fadiga das misturas. As correlações obtidas fornecem informações valiosas para o desenvolvimento de procedimentos ou propostas de especificações mais efetivas para a seleção de materiais resistentes ao dano por fadiga.
