Abstract

Perkerasan jalan yang umum digunakan di Indonesia adalah campuran Lapis Aspal Beton (Laston). Laston Lapis Aus atau Asphalt Concrete Wearing Course (AC-WC) merupakan bagian yang terletak pada lapisan paling atas dalam perkerasan lentur jalan raya. Lapisan perkerasan ini merupakan kombinasi dari aspal, agregat kasar, agregat halus, dan (filler). Filler merupakan lapisan pengisi yang berfungsi untuk mengisi ataupun menutupi rongga udara pada perkerasan jalan. Filler yang pada umumnya digunakan ialah semen, abu batu, dan abu kapur. Pada penelitian ini dilakukan alternatif pengganti filler yaitu dengan memanfaatkan limbah abu bata dan abu serbuk kayu karena limbah tersebut mempunyai senyawa kimia yang hampir serupa dengan semen Portland. Tujuan penelitian ini adalah untuk mengetahui karakteristik lapisan AC-WC menggunakan kombinasi filler abu batu dan abu serbuk kayu. Proporsi abu bata dan abu serbuk kayu yang digunakan pada penelitian ini adalah 100% : 0 %, 97% : 3%, 94% : 6%. Spesifikasi yang digunakan pada penelitian ini yaitu Spesifikasi Umum Bina Marga 2018 Metode Marshall. Setelah mendapatkan kadar aspal yang optimum untuk masing-masing filler yang berbeda variasi, uji Marshall dilakukan untuk mendapatkan nilai stabilitas dan nilai kepadatan campuran. Hasil dari pengujian menggunakan alat marshall menunjukkan bahwa semua kombinasi memenuhi Spesifikasi Bina Marga 2018. Semakin meningkat komposisi abu serbuk kayu yang digunakan maka semakin meningkat pula stabilitas yang didapatkan, yaitu hasil stabilitas tertinggi pada kombinasi 94% abu bata dan 6% abu serbuk kayu senilai 1105,11 kg dengan kelelehan 3,82 mm.

Abstract

Lapis pengikat aspal beton terletak di antara lapisan permukaan dan lapisan bawah perkerasan lentur jalan raya. Laston merupakan campuran dari agregat kasar, agregat halus dan bahan pengisi (filler). Semen portland, abu kapur dan abu terbang merupakan bahan pengisi yang sering digunakan pada perkerasan lentur jalan raya, namun bahan pengisi tersebut terbatas jumlahnya karena merupakan bahan yang tidak dapat diperbaharui. Pada penelitian ini dilakukan alternatif pengganti bahan pengisi yaitu limbah abu serbuk kayu dan abu bata yang memiliki senyawa kimia yang hampir menyerupai semen. Tujuan penelitian ini adalah untuk menganalisis karakteristik Marshall terhadap campuran AC-BC. Penelitian ini dilakukan dengan mengkombinasikan limbah abu serbuk kayu dan abu bata dengan rasio 0:100, 3:97, 6:94. Setelah mendapatkan kadar aspal optimum untuk setiap rasio kombinasi bahan pengisi maka dilakukan pengujian Marshall untuk mendapatkan nilai VIM, VMA, VFA, stabilitas, kelelehan dan Marshall Quotient. Hasil uji karakteristik Marshall dari ketiga kombinasi telah memenuhi Spesifikasi Bina Marga 2018. Namun, stabilitas tertinggi dihasilkan oleh kombinasi bahan pengisi 6% abu serbuk kayu dan 94% abu bata, yaitu 1.187,45 kg. Hasil pengujian ini menunjukkan bahwa semakin tinggi persentase abu serbuk kayu yang digunakan maka nilai stabilitas juga mengalami kenaikan.

Abstract

The road pavement that was inundated by peat water would be easily damaged since asphalt is quickly oxidized by acid in peat water. This damage could also occurred due to inundated by rain. The road pavement submerged by rainwater will make aggregate and asphalt easily separated. This study aims to determine the impact of peat water and rain on the characteristic of AC-WC asphalt through Marshall tests using asphalt penetration 60/70. The tests were carried out using the Marshall tests based on the Indonesian Standard from Bina Marga 2018. The specimens were soaked for 24, 48, 72, and 96 hours in the temperature of 60°C. The tests results shows that immersion in the peat water and rain could decreased the stability of asphalt value as soaking time increased. Based on the results, it is shown that the asphalt has stability values of 1103.68 kg, 948.81 kg, 854.48 kg, and 780.55 kg, respectively, after soaked in peat water for 24, 48, 72, 96 hours. Also, it is shown that the asphalt has stability values of 1206.43 kg, 1185.68 kg, 978.94 kg, dan 889.85 kg, respectively, after soaked in rain water for 24, 48, 72, 96 hours. In peat water, the asphalt has RSI value of 95.83%, 82.38%, 74.19%, 67.77%, respectively, after soaked for 24, 48, 72, 96 hours and in rain water, the asphalt has RSI value of 97.18%, 95.51%, 78.85%, 71.68%, respectively, after soaked for 24, 48, 72, and 96 hours. It was obtained that asphalt soaked in rain water has a better RSI value than asphalt soaked in peat water and it is complied with the requirement of Bina Marga 2018 (90%).Keywords: Rain, peat water, AC-WC

Abstract

The Population growth and development in an area lead to increased water demand and reduced use of green land. These changes can cause environmental degradation, decrease in environmental quality and existing water resources. Therefore, wise and sustainable development is needed for society. In this case the Government of Pekanbaru City has included a policy on Water Resources and Infiltration Wells in the Regional Regulation (PERDA No. 10 of 2006). One of the main objectives of implementing the PERDA is to prevent stagnation of water during the rainy season which can be detrimental to the community, especially in residential areas and other buildings. However, some researchers has stated the reality in the field that the implementation of this PERDA is not going well. Technical provisions for the use of infiltration wells are water level elevation and soil permeability which must meet the requirements. Therefore, this study aims to measure the elevation of the groundwater table, test the permeability of the soil and present the test values and measurements on a spatial map Therefore, this study aims to measure the elevation of the groundwater table, test the permeability of the soil and present the test and measurement values into a spatial map based on a geographic information system (GIS). This spatial map depicts the coordinates of sampling points that provide information on permeability values and groundwater levels, as well as recommendations for making infiltration wells at each sample point that meet the requirements. Thus, this spatial map can help residents or the government to obtain information on which locations are recommended for infiltration wells, because not all locations can be used.
