Abstract

Aggregates are a significant feature of asphalt mixtures, which significantly affect the volumetric properties and mechanical performance. Layers of concrete asphalt consist of a mixture of fine aggregates, coarse aggregates, and fillers mixed with penetration grade asphalt. The concrete pavement layer (asphalt concrete) has several types: wear surface layer, intermediate surface layer, and foundation layer. The experimental research method with the gradation testing method using the Sieve Shaker machine with aggregate objects. The aggregate used in the form of fine aggregates from Lumajang sand and coarse aggregates from Kediri Kediri is taken randomly with a maximum size of 2.36 mm, aggregate used in the form of corals originating from Kedak area, Semen Subdistrict, Kediri Regency with a maximum size of 19mm. This study aimed to determine the feasibility of aggregate classification in the classification of road pavement layers. The study was conducted using the Sieve Shaker machine with reference to the AASHTO T27. This study obtained the results that the aggregates tested from the Kedak, Kediri, and Pasir Lumajang regions deserved to be included in the Asphalt concrete A.C-B.C category in accordance with Bina Marga Division 6.

Abstract

Kediri is the third largest city in East Java after Surabaya and Malang with a population growth of 289,418 people in 2023. The International Airport will open at the end of 2023 in Kediri. However, rapid population growth has also led to an increase in mobility and the number of motorized vehicles on the streets of Kediri City, including at the research site in Dhoho Plaza. The analysis of the signaled intersection was carried out using the MKJI 1997 method, and Visual PTV Vissim for three days on Monday, Friday, and Sunday. Based on the results of the analysis, a cycle time of 90.7 was obtained which affected saturation in each arm of the intersection. There is a potential reduction in signal light waiting time from 135 seconds to 118 seconds by repairing side obstacles. The solution to overcome side obstacles is to improve facilities such as traffic lights and adjust the timing of signal lights. The change in the value of side barriers also has a significant impact on waiting times, queues, and fuel costs at the intersection of Pasar Pahing, with congestion cost efficiency reaching Rp. 22,679,183 in the next 5 years.
