Abstract

One of the causes of floods is the delays in the rate of infiltration of water into the soil due to construction activities that cause surface runoff. Porous paving block is an alternative construction material that can prevent surface run off due to the existence of porous structure. However, the porous paving block that we obtained in previous study had inadequate mechanical properties. In order to improve mechanical properties of the porous paving block, the addition of fine aggregates is essential. The objective of this study was examined the addition of fine aggregates on the mechanical properties of the porous paving block, while maintain the ability to pass the water. Porous paving block (210 × 105 × 60 mm3) was fabricated by the variation of fine aggregate (0, 3, 5, 7, 9, and 11 wt.%). Mechanical properties of the porous paving block was measured by compression test using hydraulic press machine. The result showed the addition of fine aggregates increased the mechanical properties of the paving block. The compressive strength of porous paving block without and with the addition of 11 wt.% fine aggregates was 11.27 ± 1.93 and 21.13 ± 0.54 MPa, respectively. According to the SNI 03-0691-1996, the compressive strength of this porous paving block is categorized as B class. In addition, the water infiltration test of porous paving block was 66.99 – 133.36 mm/hour. The lowest of water infiltration was obtained by the addition of 11 wt.% of fine aggregates. Therefore, the porous paving block that investigated in this study is suitable for utilization in parking area, pedestrian, and park. Keywords: Porous paving block; Fine aggregate; Compressive strength; Infiltration Salah satu penyebab banjir adalah tertahannya laju infiltrasi air ke dalam tanah yang dikarenakan oleh aktivitas pembangunan sehingga mengakibatkan limpasan permukaan. Paving block berongga merupakan salah satu alternatif lapis perkerasan yang dapat mencegah limpasan permukaan dikarenakan menggunakan material berpori. Namun, paving block berongga pada penelitian sebelumnya tidak memiliki kekuatan yang memadai (mutu D berdasarkan SNI 03-0691-1996). peningkatan kekuatan mekanik paving block berongga dapat dilakukan dengan cara penambahan agregat halus. Tujuan dari penelitian ini adalah menambahkan agregat halus untuk meningkatkan kekuatan paving block berongga dengan tetap mempertahankan kemampuan infiltrasinya. Paving block berongga (210 x 105 x 60 mm) dibuat dengan variasi penambahan agregat halus 0,3,5,7,9,11% dari berat agregat kasar. Pengujian kekuatan tekan paving blok berongga dilakukan dengan mesin uji tekan hidrolik. Hasilnya menunjukkan bahwa penambahan agregat halus berbanding lurus dengan kekuatan tekannya. Kekuatan tekan paving block berongga tanpa agregat halus dan dengan penambahan agregat halus 11% masing-masing sebesar 11.27  1.93 dan 21.13  0.54 MPa. Berdasarkan SNI 03-0691-1996, kekuatan tekan tertinggi dari paving block berongga ini masuk kedalam mutu B. Selain itu, uji infiltrasi pada paving block berongga adalah 66.99 – 133.36 mm/jam. Nilai infiltrasi terendah didapatkan pada variasi penambahan pasir 11%. Paving block berongga dari hasil penelitian ini dapat dimanfaatkan untuk area parkir, pejalan kaki, dan taman.
