“…Conclusions obtained: (1) Marshall parameter test results show that the AC-WC mixture with or without the addition of PET can meet the Indonesian National Standard (SNI) code. (2) The pattern of the changes in the variation of PET content with the Marshall parameter is consistent with that found in previous studies. The addition of PET content can reduce an AC-WC mixture's density value by 0.5%, its VFA value by 3%, and its flow value 18%, but the flow value increases again after reaching the lowest value.…”

Lately, plastic waste has become a problem in our society, due to the negative impact that it has on our environment. To mitigate this, the reuse of plastic bottle wastes and other local materials should be encouraged. In this paper, the authors present an innovative application for polyethylene terephthalate (PET) that is obtained from plastic bottle wastes, as an additive to Asphalt Concrete-Wearing Course (AC-WC), a hot mix asphalt (HMA) type. The AC-WC sample that contained the PET was measured using the wet method to determine the Marshall parameters of the samples. The type of bitumen used as the specimen is asphalt, which has a penetration value of 60/70. The optimum asphalt content (OAC) obtained from the preliminary study was found to be 5.7% of the total asphalt weight. The results show that AC-WC mixture strength improves when plastic bottle waste is used, which can be correlated with an increase in stability. This finding shows that plastic bottle waste and other local materials have an alternate use as a road pavement material.

“…Lately, the use of recycled waste materials as additives to improve the properties of asphalt mixtures has brought environmental, economic, and technical benefits [1,2]. Premature damage to road pavement can occur due to poor asphalt performance resulting from insufficiencies in the concrete mix.…”

“…The relationship between density and seed polymeric HDPE material is consistent with findings from previous studies. Previous research [34] found that replacing various percentages of mineral aggregates with HDPE plastic ore content reduced the density of the mixture by 2.5 percent for 20 percent HDPE content and 6.8% for 60 percent HDPE content. The plastic content can lower the density of the mix, reducing the adhesive connection between the asphalt and the aggregate and the asphalt mixture's rutting resistance, reducing the asphalt pavement's service life [34].…”

“…According to Giri et al (2020) [34], the density of bituminous asphaltic concrete (BAC) with an increasing plastic content would decrease. Furthermore, the density shift is caused by partial filler replacement with a lower density material than the reference filler, with the density drop proportional to the amount of material injected [34]. The density of the mixture, on the other hand, increases when a substance with a higher density is added [35].…”

Plastic waste processing is a problem that almost several countries in the Asian region are unable to overcome. One of the latest innovations carried out in the field of road pavement construction is mixing HDPE type plastic waste that has been processed into plastic seeds into the asphalt concrete mixture. Previous research has shown that HDPE plastic waste may be reused to improve the physical properties of temperature-sensitive asphalt and improve the stability of asphalt concrete. This study was conducted to determine the effect of using HDPE plastic ore as a mixed additive on the Asphalt Concrete-Wearing Course (AC-WC) using Marshall parameters. Marshall Parameters used are stability, flow, VIM, VMA, VFA, and MQ. The study was conducted in a laboratory by testing 42 samples with different levels of HDPE plastic seeds, mixed using wet methods to determine Marshall Characteristics. Manufacture of test objects using asphalt type, which has a penetration rate of 60/70. The initial research results showed that the optimal asphalt content (OAC) is 5.5%, with the percentage content of HDPE plastic seeds around 0, 1, 2, 3, 4, 5, 6, and 7% compared to asphalt weight. The results showed that the effect of HDPE plastic seed content on the AC-WC mixture increased the value of Marshall Characteristics and met all the requirements of SNI 06-2489-1991. This finding shows that HDPE plastic seeds deserve to be an alternative material for road pavements. Doi: 10.28991/cej-2021-03091744 Full Text: PDF

“…Porém, no desempenho do comportamento mecânico existem discrepâncias. Por um lado, alguns pesquisadores apresentam maior rigidez, maior resistência à deformação permanente e maior resistência à danos por umidade induzida das misturas com RCA quando comparadas com as misturas convencionais [1,17,[19][20][21][22] Por outro, alguns autores relatam resultados contrários [15,[23][24][25][26]. Isso é amplamente atribuído à origem, características físicas, composição química e mineralógica dos RCAs.…”

Incorporação de pó de agregados reciclados de concreto como fíler em misturas asfálticas

RESUMO A geração e o gerenciamento de resíduos sólidos industriais consideram-se uma problemática ambiental no mundo. Vários estudos têm se concentrado na utilização de resíduos da construção civil no âmbito da pavimentação. O objetivo deste artigo é avaliar o uso do pó de agregados reciclados de concreto RFPA (Recycled Fine Aggregates Powder) no Concreto Betuminoso Usinado a Quente (CBUQ). Para tal fim, se fabricaram três tipos de misturas asfálticas: a mistura de referência com materiais convencionais e dois misturas de estudo com substituição do 3% e 6% do filer natural pelo RFAP (composição total da massa da mistura). Avaliou-se a resistência sob carga monotônica das misturas (Ensaio Marshall e Tração Indireta-RT) e a resistência ao desgaste Cântabro. Uma análise de variância (ANOVA) foi realizada para verificar se os resultados obtidos eram estatisticamente significativos. Ao substituir a 3% do fíler da granulometria pelo pó RFAP, obteve-se um comportamento mecânico satisfatório sob a ação das cargas monotônicas, embora houvesse aumento da perda de massa no ensaio Cântabro. Os resultados evidenciam que a utilização do RFAP da forma proposta é viável desde o ponto de vista técnico e ambiental, por permitir uma forma de disposição final segura de resíduos.
