Abstract

The background to the research that will be carried out is that the large amount of standing water on the road pavement in each rainy season results in disturbances to motorists' comfort. This is due to impermeable road pavement and poor drainage along the road. Porous asphalt can increase rainwater absorption, thereby reducing puddles on the road surface. Porous asphalt is a new breakthrough in the world of road pavement to reduce the appearance of puddles of water when it rains. Porous asphalt is also designed to have high porosity so that water can flow through side channels and a waterproof base layer to prevent water from seeping into the subbase layer and road body so as to minimize puddles of water on the road surface which often occur after rain and disrupt the smooth flow of traffic. cross. Advances in road pavement technology have encouraged researchers to conduct research using palm shell ash (fly ash) as a filler in porous asphalt mixtures. The use of palm shell ash is expected to increase the stability value and have large cavities so that water can pass through the road surface, as well as to reduce palm oil waste in Indonesia. The objectives of this research are 1. To find out the optimum asphalt content value in porous asphalt mixtures, 2. To know the results of using palm shell ash at 0%, 1% and 2% as a filler for porous asphalt mixtures in flexible road pavement. The research method is Marshall and Permeability Testing. The tests that will be carried out on a laboratory scale use an AC-WC hot mix asphalt system with guidance, namely the basics of asphalt concrete road construction. The research results showed that by adding palm shell ash as a filler in making AC-WC type porous asphalt, it showed that the stability value was higher, while the permeability value was lower, meaning that the addition of palm shell ash to the porous asphalt mixture did not have a significant effect because it was smaller. air voids in the mixture. The addition of palm shell ash to the porous asphalt mixture increases the stability value which can increase the ability of road construction to accept loads, but the pavement layer is not permeable and water flows over the surface more slowly.

Abstract

Paving block merupakan campuran yang terdiri dari semen portland, agregat halus dan air. Material ini populer di kalangan masyarakat sebagai penutup tanah pada area seperti tempat parkir, taman, halaman sekolah, dan lain-lain. Kepulauan Riau dikenal sebagai penghasil cangkang gonggong dalam jumlah yang cukup besar, namun cangkang gonggong ini hanya sebagai limbah oleh masyarakat disekitar. Tujuan dilakukan penelitian ini adalah untuk mengatasi masalah penumpukan limbah cangkang kerang gonggong yang berpengaruh terhadap kebersihan dan kesehatan masyarakat setempat dan sebagai pengembangan material alternatif dalam mencari bahan pengganti yang lebih murah dan berkelanjutan untuk material konvensional khususnya agregat halus pada campuran paving block. Selain itu penelitian ini untuk mengetahui bagaimana pengaruh penggunaan serbuk cangkang gonggong sebagai pengganti agregat halus terhadap kuat tekan paving block. Dimana diketahui bahwa cangkang kerang gonggong kandungan CaO nya sebesar 94,05% sehingga dapat digunakan sebagai pengganti agregat halus pada campuran paving block. Pemanfaatan limbah cangkang gonggong digunakan untuk penelitian sebagai substitusi parsial agregat halus pada paving block dengan komposisi campuran 0%, 30% dan 40%. Untuk pengujian kuat tekan dilakukan pada umur 28 hari. Digunakan metode uji mekanis utama untuk paving block sesuai SNI 03-0691-1996. Cetakan paving block berukuran 10,5 cm x 10,5 cm x 6 cm. Pada penelitian ini diperoleh persyaratan minimum mutu B dan A yaitu 21,97 MPa, 25,2 MPa, dan 35,01 MPa. Kesimpulannya menunjukkan bahwa penggunaan serbuk cangkang gonggong sebagai substitusi sebagian agregat halus pada paving block di atas 30 % mengalami peningkatan kuat tekan.
