Abstract

Jalan yang sering dilalui kendaraan berat, mengakibatkan penuaan aspal yang dapat menurunkan kualitas aspal tersebut. Inovasi yang dilakukan, yaitu memanfaatkan limbah aspal yang termodifikasi dengan ekstraksi bubuk lindi hitam atau lignin. Penelitian ini untuk mengetahui karakteristik pengikat aspal bekas pakai dengan tambahan lignin dengan kadar 0%, 3%, dan 6%. Pengujian reologi aspal meliputi berat jenis, penetrasi, daktilitas, titik lembek, viskositas.Penelitian ini menunjukkan bahwa aspal bersifat sangat kaku dan membutuhkan suhu yang sangat tinggi untuk mencair. Hasilnya terbukti dari titik lembek tertinggi (78,5°C pada kadar lignin 6%), penetrasi terdalam (9,33 mm pada kadar lignin 0%), daktilitas terpendek (4,15 cm pada kadar lignin 6%), nilai viskositas yang mendekati spesifikasi bina marga (3592,205 cSt pada lignin 3%), Kesimpulannya, bahan zat aditif lignin mampu membuat aspal semakin kaku dan keras dan tidak baik untuk bahan peremajaan aspal.

Abstract

The slowing down of vehicle speed that occurs on Jalan Diponegoro is caused by the behavior of vehicles that make intertwining movements (weaving). This condition causes vehicles traveling straight to reduce vehicle speed due to the presence of vehicles entering from Jalan Dr. Cipto Mangunkusumo towards Jalan Diponegoro. Queues that occur on Jalan Diponegoro cause a narrowing of the road, which can cause travel delays. The aim of this research is to analyze travel delays due to interwoven conflicts or weaving that happened on Jalan Diponegoro. This research was analyzed using the method gap acceptance. According to the results of data processing analysis and literature studies, the delay time was 23.28 seconds in the morning and 13.77 seconds in the afternoon for each 5 minute time interval. Key words: Travel Delay, InterwovenConflict, Gap Acceptance.
