“…The results show that the WBP loading at convenable rate is suitable for asphalt improvement for road pavement and the best polymer-modified asphalt are obtained at the WBP loading of 5wt% to 10wt%. This study can be compared to the inclusion of thermoplastic ethylene-vinyl acetate (EVA) with the optimum content of approximately 5-6% of the bitumen weight (Daniel et al, 2022). These effects were observed by (Boukhari et al, 2015) which recommended the addition content between 2% to 8%.…”

“…The application of polymer in an asphalt concrete (AC) mixture has reached wide popularity lately to deal with the increasing demand for higher quality roads with heavier traffic. The thermoplastic is one of the of the most popular polymers employed (Daniel et al,2022). The present study focused on the use of WPB in an AC mixture.…”

The aim of the study is to formulate a new composite material for road pavement by combining asphalt concrete with waste plastic bags (WPB). The study focused on enhancing the physical and mechanical properties of the composite materials by adding varying proportion of WPB. WPB is prepared simply by cleaning and melting them at 300 °C. Then, the melted WPB is mixed with asphalt at 170 °C for 2 to 3 minutes. The resulting mixtures contained different content of WPB by weight such as 0wt%, 5wt%, 10wt%,15wt% and 20wt%. The homogenized mixtures underwent penetration and softening point tests. Additionally, Marshall stability tests were conducted with 0/14 aggregates, along with asphalt concrete (AC) flow tests, Duriez stability reports, and AC compacity tests. The water content of AC was also examined. The results show that as the content of WPB increased, penetration values exhibited a consistent linear decrease. The incorporation of WPB resulted in an average increase of 22.64% in the softening point of asphalt. Increasing the content of WPB led to an average 72.07% rise in Marshall stability, accompanied by a concurrent 29.47% decrease in AC flow. In addition, at 10wt% WPB incorporation, there was an optimal Voids in Mineral Aggregates (VIM) value of 2.07%. The Duriez test revealed an average increase of 15.18% in the stability of asphalt concrete. The compacity of asphalt concrete (AC) experienced an increase, and concurrently, the AC water content also increased. Conclusively, the incorporation of melted WPB effectively improved the physical and mechanical properties of asphalt, showcasing promising prospects for road pavement applications. The study suggests that the polymer-modified asphalt is achieved with WPB loading optimal ranging from 5wt% to 10wt%. This innovative approach holds potential significance, especially in underdeveloped countries where there is an abundant supply of waste plastic bags.

Hal ini menunjukkan adanya peran positif polimer dalam meningkatkan kekakuan, seperti yang telah ditunjukkan pada penelitian penulis sebelumnya (Daniel et al, 2022), serta ikatan dalam campuran aspal sehingga menghasilkan campuran dengan sifat mekanis yang meningkat. Nilai energi fraktur mengalami peningkatan maksimum sebesar 150% dan 145% pada kondisi kering dan basah, yang juga dihasilkan oleh sampel dengan modifikasi polimer sebesar 5%.…”

Studi ini mengevaluasi efek dari penambahan polimer Ethylene-Vinyl Acetate (EVA) kepada ketahanan campuran aspal hangat terhadap rendaman air (moisture damage). Pengujian Semi-Circular Bending(SCB) menggunakan sampel yang dibuat berdasarkan standar Bina Marga 2018 dengan modifikasi oleh penambahan EVA sebesar 4% - 6% dari berat bitumen. Sampel yang dibuat dibagi dalam dua grup, dimana kelompok pertama direndam selama 24 jam pada suhu 60oC berdasarkan ASTM D1975-11, sementara kelompok kedua didiamkan pada suhu ruang. Kedua grup ini kemudian melalui pengujian SCB berdasarkan standar ASTM D8044 – 16 dan NEN-EN 12697-44. Hasil pengujian menunjukkan peningkatan kuat tarik, energi fraktur, flexibility index (FI), dan crack resistance index (CRI) sebesar 5 – 34% maksimum pada kondisi sampel kering yang dihasilkan dari penggunaan fiber dengan dosis 0.3%. Sementara itu, spesimen modifikasi fiber yang melalui simulasi perendaman air menunjukkan kenaikan kapasitas deformasi (FI dan Jc) hingga mencapai 1 - 45% dibandingkan sampel kontrol. Hanya saja, penambahan 0.5% fiber menghasilkan rasio kuat tarik basah / kering terbesar mencapai 123%,sedangkan penambahan 0.3% menghasilkan rasio FI terbesar mencapai 120%. Dapat disimpulkan bahwa penambahan fiber selulosa menghasilkan dampak positif dengan variasi efek, dengan penambahan 0.3% menghasilkan kekuatan dan ketahanan terbesar pada kondisi kering, sedangkan penambahan dengan kadar 0.5% menghasilkan peningkatan kekuatan dan ketahanan terhadap retak yang terbaik dalam kondisi basah.

This research aims to observe the effect of applying cellulose fibre to the mechanical properties of bituminous mixtures when subjected to various loading speeds that simulate various traffic situations with fibre dosages of 0.3 – 0.5% of mix weight. The semi-circular bending (SCB) test was employed in this project, where the specimens were subjected to loading speeds of 0.25, 0.5, and 1 mm/min. The incorporation of cellulose was reported to enhance the tensile strength of the specimens up to 43.75% at the lowest loading rate and 13.75% at the highest rate, while the critical strain energy was elevated to 24.54% at the lowest rate and 38.2% at the highest rate, signifying better resistance against loading. Meanwhile, the flexibility index (FI) of modified specimens showed a mixed trend compared to the control mix, 30.43% higher at the lowest rate and 28.9% lower at the highest rate. To sum up, the incorporation of cellulose fibre into the bituminous mixture can enhance its strength and resistance against various loading rates, and the fibre dosage of 0.3% is recommended to give the best outcome.
