Polymer science is one of the few fundamental research fields where the results can be transferred into real-life products almost immediately. Industries need collaborations with the best researchers (universities or national laboratories) to elevate the field and favor the development of new materials, which will boost the chemical and materials business economy and ensure that innovative and sustainable polymer products are constantly being brought to the market. The mechanisms to ensure a seamless and fruitful collaboration are numerous, but few approaches really manage to incorporate the full range of polymer research from a molecular understanding to a macroscopic control of properties. We review some of the main components of standard industry–academia collaborations and propose to develop polymer open centers that put the business development objective as the starting point of the collaboration and allow those to gather and focus on different scientific fields toward a common objective.

“…Recently, Rodrigues et al. (2019) demonstrated the applicability of the NVCZ to predict the FAM damage behavior at one loading rate assuming the simple power‐law damage evolution proposed by Allen and Searcy (2001) as follows:

\dot{α} = A {([], λ ((), t))}^{m}, when \dot{λ} > 0 and α < 1

\dot{α} = 0, when \dot{λ} \leq 0 or α = 1

where A and m are material‐specific constants that govern the damage evolution behavior.…”

“…Considering that bituminous media exhibit highly rate‐dependent viscoelastic and nonlinear behavior, cracking can be effectively modeled by the extrinsic nonlinear viscoelastic cohesive zone (NVCZ). Several recent publications (Rodrigues et al., 2019; You et al., 2018; Zhang et al., 2020) have attempted the extrinsic NVCZ model to represent the complex cracking of paving materials. However, these studies presented the applicability of the NVCZ considering a phenomenological damage evolution law, and its full capability to account for the rate‐dependent fracture process was not demonstrated.…”

Cracking of bituminous materials is one of the main distresses that results in roadway failure. As bituminous media are highly rate‐dependent at intermediate temperatures due to the viscoelastic nature of the binding materials, cracking is also highly rate‐dependent viscoelastic. This presents a clear need to address the phenomenon in the modeling‐analysis process for a more accurate design of mixtures and pavements. This study proposes an advanced computational modeling method to predict complex rate‐dependent cracking in bituminous materials and pavements. In particular, we explored an extrinsic nonlinear viscoelastic cohesive zone (NVCZ) integrated with Gaussian damage evolution. To examine the modeling method and its validity, two modeling efforts in multiple length scales were made: mm‐scale material‐level modeling and cm‐m scale hierarchical modeling that linked the mixture with pavement structure. The NVCZ modeling with Gaussian damage evolution successfully predicted material cracking and damage at different loading rates by using a single set of fracture parameters. This implies that the complex cracking behavior of bituminous materials can be characterized by material‐specific fracture parameters that can be identified by a simple fracture test. The pavement modeling through a parametric analysis demonstrated the sensitivity and capability of the modeling to effectively capture the interrelated influence of several core design variables, such as traffic, material properties, and layer configurations, all of which affect pavement responses and damage evolution. The computational modeling presented in this study has the scientific rigor to predict nonlinear rate‐dependent viscoelastic fracture of bituminous materials and pavements with a good modeling efficiency by significantly reducing laboratory tests.

“…FAM is defined as a composite comprised of fine aggregates and mastic, which represents the internal structure of the asphalt concrete. As claimed by several researchers, fatigue cracking and moisture damage are phenomena typically related to the fine portion of the asphalt mixtures (Kim, Little e Song, 2003;Zollinger, 2005;Bhasin, 2006;Masad et al, 2006;Arambula, Masad e Martin, 2007;Caro et al, 2008aCaro et al, , 2008bCastelo Branco et al, 2008;Vasconcelos, Little e Bhasin, 2010;Coutinho et al 2010;Vasconcelos et al, 2011;Coutinho, 2012;Sousa et al, 2013;Underwood e Kim, 2013;Karki, Li e Bhasin, 2015;Gudipudi e Underwood, 2015Freire et al, 2017;Fonseca et al, 2019;Rodrigues et al 2019). One of the approaches adopted in studies on fatigue characterization is based on the viscoelastic continuum damage theory (VECD).…”

A crescente produção mineral gera volumes gradativamente maiores de resíduos sólidos, motivando a realização de estudos que viabilizem o aproveitamento desses resíduos em outras áreas. O objetivo deste trabalho é avaliar a utilização do rejeito de flotação do minério de ferro, que se assemelha a uma areia fina, como material constituinte de misturas asfálticas. Foram produzidas misturas asfálticas completas (MAC) e matrizes de agregados finos (MAF) empregando agregados de gnaisse e rejeito de minério de ferro. A MAC foi avaliada por meio da resistência à tração e dano por umidade induzida. As MAFs foram submetidas a ensaios de fadiga no reômetro de cisalhamento dinâmico, gerando modelos de fadiga das amostras com e sem condicionamento à umidade. A melhor adesividade do ligante asfáltico ao rejeito proporcionou maior resistência à tração na MAC e maior vida de fadiga à MAF condicionada, além de reduzir a suscetibilidade à umidade nas duas escalas.
