Avaliação da resistência ao trincamento de misturas asfálticas compostas por agregados miúdos com diferentes tamanhos máximos nominais

Abstract: Os pavimentos asfálticos devem possuir uma qualidade mínima para que estejam adequados às suas necessidades de uso. Um problema comum nos pavimentos no Brasil e no mundo é o trincamento motivado por fadiga. Esse problema é caracterizado pela repetição de carga atuante no revestimento asfáltico, gerando, inicialmente, microfissuras. Com o passar dos anos, as microtrincas coalescem dando origem às macrotrincas que, ao final da vida útil, podem levar o material à completa ruptura.Recentemente, autores têm utiliza… Show more

“…There are also evidences (Freire et al 2014) that the fatigue characteristics of the samples made with particles passing sieve #10 and #16 are not affected by aggregate size. In order words, this means that both aggregate sizes can be used to represent the FAM.…”

“…Dai and You (2007) (Coutinho, 2012;Pazos, 2015). Due to this condition, Freire et al (2014), Freire (2015), Freire et al (2015), and Freire et al (2017) investigated the influence of different NMAS, i.e., #16 (1.18 mm), #10 (2.00 mm) and #5 (4.00 mm), in the fatigue properties of the FAMs. Based on the studies about the adequate NMAS for the FAM presented in this section, the FAMs evaluated in this research were produced with fine aggregate particles passing sieve #10 (2.00 mm).…”

“…Brazilian researchers investigated the influence of different NMAS, i.e., #16 (1.18 mm), #10 (2.00 mm) and #5 (4.00 mm), in the fatigue properties of FAMs (Freire et al, 2014;Freire, 2015 andFreire et al, 2017). The NMAS of #10 (2.00 mm) was considered suitable, because the fatigue curves of the FAMs presented slope similar to the curves for the HMA mixture.…”

“…In Brazil, the research carried out by Coutinho et al (2010), Coutinho et al (2011) and Coutinho (2012) uses sieve #10 (2.00mm) as the sieving limit of the fine fraction, because sieve #16 (1.18mm) is not part of the the Brazilian sieve series and is close to the American sieve. Freire, Castelo Branco and Vasconcelos (2014) tested samples made with particles passing sieves #10 and #16 for fatigue damage, and concluded that there are evidences that the fatigue characteristics are not affected by this difference on the aggregate size, meaning that both maximum aggregate size can be used to represent the fine portion.…”
