Análise teórico-experimental do módulo dinâmico de compósitos asfálticos com argila calcinada

Abstract: INTRODUÇÃOO agregado sinterizado de argila calcinada (ASAC) apresenta-se promissor para localidades que apresentam dificuldades na obtenção de materiais pétreos, com vistas à produção de agregado graúdo (brita), e ao mesmo tempo possuem abundância de solos argilosos. Esta é a realidade presente em grandes regiões do Brasil, com destaque na pavimentação asfáltica de rodovias em trechos distantes dos centros urbanos, como são os casos da BR 163 (Santarém, PA -Cuiabá, MT) e BR 319 (Manaus, AM -Porto Velho, RO), s… Show more

“…However, in conditions where there is an insufficiency of superficial stone, these pavements can be composed of a rolled pebble from riverbeds, a solution that results in a lower technical quality of this upper layer and causes serious environmental impacts, stimulating the study of new materials. An alternative for this situation is to use sintered calcined clay aggregate (SCCA) as a coarse aggregate [2][3][4][5][6][7][8][9][10][11][12]. Specifically, regarding asphalt binder, its viscoelastic characteristics must also be taken into consideration in this composition, as its consistency and strains are a function of the variation in temperature and time of load application.…”

“…Examples include case studies from the Geotechnical Group of the Federal University of Amazonas (UFAM), in which solutions have been applied to problems in the Amazon region by several authors [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. More recently, with the advent of nanotechnology, the literature brings research with the application of nanomaterials as modifiers of asphalt binders and in asphalt mixtures, demonstrating positive effects.…”
