Abstract

Abstract: Currently the safety level in the province of NTB is above the national average safety rate, this is indicated by the accident fatality ratio per 100,000 which is 11.07 while the national average safety rate is 10.47, this figure must continue to reduce the risk factors for accidents. Based on NTB, the 2017 figures show that in 2016 the largest number of accident perpetrators were at the Junior High School (SMP) level, namely 38%. Seeing this data, it is necessary to increase public awareness of the importance of safety and how to maintain safety while driving. One of the efforts to increase public awareness of safety can be done by socializing driving safety. Safety socialization is carried out to provide understanding, awareness, and knowledge about driving procedures and how to maintain road safety.

Abstract

Cold Emulsion Asphalt Mixture (CAED) uses unheated emulsified asphalt, thus reducing gas emissions and health risks for workers. Volumetric characteristics and aggregate gradation are very important to assess the quality of CAED. Therefore, the purpose of this study is to examine the volumetric characteristics of CAED, namely Void in Mix (VIM), Void in Mineral Aggregate (VMA), and Void Filled with Bitumen (VFB), with variations in filler (cement, lime) and aggregate gradation (dense, open). The study used a laboratory experimental method, including material preparation, sample preparation with five variations of filler, testing VIM, VMA, and VFB values, and data analysis. This study shows that the volumetric characteristics of CAED with closed and open gradations meet the VMA and VFB specifications, but the VIM value is only met in the closed gradation of CAED with a variation of 50% cement:50%. Better aggregate interlocking in closed gradations results in smaller air voids. Closed gradations are recommended for heavy traffic, while open gradations are suitable for well-drained roads and light traffic
