Abstract

Laston is a layer on road construction consisting of a mixture of asphalt and aggregate that is continuously graded which is generally used for roads with heavy traffic loads. Based on function, Laston has 3 kinds of mixtures, namely Laston as an Aus layer (Asphalt ConcreteWearing Course), Laston as a binder layer (Asphalt Concrete-Binder Course) and Laston as a foundation layer (AC-Base).In the General Specification for Road Pavement (2018), hot mix asphalt concrete determines the gradation for AC-BC consisting of coarse and fine grades. In a Laston mixture, the gradation of the aggregate mixture has gradation limits, including the upper gradation limit (the smoothest) and the lower gradation limit (the coarsest), where the gradation limits give different effects on the characteristics of the Laston mixture. Laston AC-BC mixture with coarse gradation aims to determine the value of Marshall parameters (stability, flow, density, VIM, VMA, VFB), the value of Optimum Asphalt Content (KAO) and the durability of the mixture.Marshall test results for variations in coarse gradation Stability 1200kg, Flow 3.3 mm, MQ 355, VIM 4.6%, VMA 16.1%, VFB 72.0%, Density 2.283g/cm3 . Durability test results for stability 30 minutes = 1398.2kg 24 hours = 1113.0% kg flow 30 minutes = 3.075mm 24 hours = 3.45mm VIM 30 minutes = 5.59% 24 hours = 3.63% VMA 30 minutes = 17.03% 24 hours = 16.18% VFA 30 minutes = 68.96% 24 hours = 73.44% Density 30 minutes = 2.80% 24 hours = 2.30%. With KAO 5.6%. The Marshall and Durability parameter values all meet the 2018 Highways Specifications.
