Plastic waste processing is a problem that almost several countries in the Asian region are unable to overcome. One of the latest innovations carried out in the field of road pavement construction is mixing HDPE type plastic waste that has been processed into plastic seeds into the asphalt concrete mixture. Previous research has shown that HDPE plastic waste may be reused to improve the physical properties of temperature-sensitive asphalt and improve the stability of asphalt concrete. This study was conducted to determine the effect of using HDPE plastic ore as a mixed additive on the Asphalt Concrete-Wearing Course (AC-WC) using Marshall parameters. Marshall Parameters used are stability, flow, VIM, VMA, VFA, and MQ. The study was conducted in a laboratory by testing 42 samples with different levels of HDPE plastic seeds, mixed using wet methods to determine Marshall Characteristics. Manufacture of test objects using asphalt type, which has a penetration rate of 60/70. The initial research results showed that the optimal asphalt content (OAC) is 5.5%, with the percentage content of HDPE plastic seeds around 0, 1, 2, 3, 4, 5, 6, and 7% compared to asphalt weight. The results showed that the effect of HDPE plastic seed content on the AC-WC mixture increased the value of Marshall Characteristics and met all the requirements of SNI 06-2489-1991. This finding shows that HDPE plastic seeds deserve to be an alternative material for road pavements. Doi: 10.28991/cej-2021-03091744 Full Text: PDF

Road infrastructure development in a country has been considered an important predictor of economic development and prosperity. Hence applying a systematic analysis approach, this study aims to project the future role of the central government in developing road infrastructure and its significance in the country's economic growth. The main data sources were the literature review and expert opinions in the form of self-administrative surveys and interviews. Besides, the Cross-impact Direct Influence (CDI) matrix was applied to formulate the questionnaire. For the data analysis purpose, MICMAC analysis and Scenario Wizard software were used. The MICMAC analysis results revealed the dominant role of 9 important/key variables in developing the Indonesian road infrastructure. Simultaneously 24 positive states of the important variables what identified via the Scenario-Wizard Method. Findings also depicted stronger consistency among the four scenarios. Whereas Scenario 1 showed the most ideal 9 key features related to Indonesia’s road infrastructure developments with a high intensity of concentrating the efforts on planning road infrastructure development in big cities and use of smart and modern technology. Moreover, presenting a group of constructs for developing road infrastructure and resultant economic growth in the country, the current study adds value to the existing literature.

Side friction is a towards the flow roadway at an internode road which is able to cause a conflict and has big effect for the activities in roadway. Side frictions which were effected the capacity and pedestrians in city road were pedestrians, transportations which stopped, slow transportations (bicycle, wheelborrow, etc) and transportations which were went in and out from the side internode road. The purpose of this research is to find out the significant effect of side friction toward the road performance. After several stages in collecting the data and data analysis using method (MKJI 1997), it can be concluded that the effect of side friction toward the performance at Yos Sudarso street for the relation between road volume with side friction which has the highest correlation score was transportations which were went in and out at 0,260. Meanwhile, the relation of rapidity transportations with side friction which has the highest correlation score was the transportations which stopped at 0,495. The factor that effected the internode performance at Yos Sudarso was the side friction which has the highest score after the transportations which went in and out started at 17.00 – 18.00pm, so the total was 1.278,90.

Plastic Waste (PW) is one of the primary sources of pollution, leading to drainage system blockages, thereby causing floods and road pavement damage. One of the major ways to reduce pollution due to plastic waste and excessive exploitation of natural resources is through the development of HDPE. It is also important to reduce damage to road pavement structures by improving the quality of the asphalt used during construction. Therefore, this research aims to analyze the effects of using HDPE shale, an ecologically friendly material, and the addition of Wetfix-Be to asphalt pavements in tropical climates. The study results showed that 5.75% of the OAC asphalt using plastic waste raises the stability value and meets the specification requirements. Specimens of AC-WC concrete asphalt mixture were also tested by immersing them in fresh and seawater for 0.5, 24, 72, and 96 hours. In conclusion, using HDPE plastic waste and Wetfix-Be keeps the AC-WC concrete asphalt mixture stable. Doi: 10.28991/CEJ-2022-08-08-010 Full Text: PDF
