Abstract

Hot Rolled Sheet or Thin Layer Asphalt Concrete is a graded gap mixture that uses fine coarse aggregate, fillers, and asphalt in a certain ratio which is compacted hotly. HRS has high durability. Filler functions as a filler for voids between aggregates, the fillers that are often used are cement and fly ash. In this study, the filler used was coffee grounds waste.The purpose of this study was to analyze the effect of adding coffee grounds waste to the properties of the HRS-WC mixture with immersion variation. This study used coffee grounds waste with the addition of 20%, 40%, 60%, 80% and 100%. Samples were made of 61 briquettes consisting of 21 characteristic briquettes and 40 variation briquettes. Some samples were not immersion and some were immersion for 3, 7 and 14 days. Sampling refers to the 2018 Bina Marga Specifications. Sample testing uses a Marshall Test. The test results show that the effect of adding 20% coffee grounds waste with 3-day immersion, the Stability, Flow, Density, Marshall Quotient, VIM, VMA, and VFB values are all within the 2018 Bina Marga Specifications.

Abstract

Cold Paving Hot Mix Asbuton is a mixture of asbuton consisting of aggregate, grainy asbuton, rejuvenator, and other additional materials mixed hot and laid cold. Asbuton Cold Paving Hot Mix (CPHMA) is a ready to use asphalt mixture product used as a surface layer for low traffic volume road pavement. This study aimed to calculate and analyze the effect of adding waste used oil to the hot asphalt mixture type CPHMA with soaking time variation on the value of asphalt mixture/marshall properties. This research used used oil with oil content of 5%, 10%, and 15%. Testing was carried out using the Marshall test apparatus. The results showed that the soaking time variation affects the mechanical properties of CPHMA asphalt. The longer the soaking time, the lower the properties of the mixture. The effect of used oil as an additive in the CPHMA asphalt mixture with the best soaking time and the maximum result is obtained when soaked for 5 days with 5% used oil content.

Abstract

CPHMA (Cold Paving Hot Mix Asbuton) is a new breakthrough to meet the needs of remote areas where the asphalt mixing plant (AMP) is inadequate and is expected to add value to stability and durability. Natural Rubber (Latex) is a type of natural rubber that has high resistance to cracking and has high adhesion. The purpose of this study was to determine how much influence the addition of natural rubber (latex) had on marshall characteristics in CPHMA mixtures with variations of immersion. This study used natural rubber (latex) additives with levels of 10%, 15% and 20%. 33 samples of test objects were made, 6 normal samples and 27 variations samples. The treatment of the specimens was carried out with variations of immersion for 7, 14 and 21 days. Testing is done with the marshall test tool. The test results showed that Natural Rubber (Latex) as an added ingredient in CPHMA-type Buton asphalt mixture by immersion caused the value of the properties of the mixture to not meet specifications and could not be used.

Abstract

The development of cities and the rapid growth of Indonesia's population have caused the traffic volume in Makassar City to continue to increase. As the provincial capital and center of economic, industrial, trade and educational activities in South Sulawesi, Makassar City is also the center of the traffic flow of goods and services from the surrounding area. The impact of the growth of trade and service centers that attract the movement of visitor vehicles is an increase in the need for parking spaces. This study aims to determine the impact of on-street parking on speed and traffic density on Jalan Tamalanrea Raya and to provide a basis for developing solutions. The survey was carried out for 3 days a week, 20 October – 24 October 2022. The location of the research object is located on Jalan Tamalanrea Raya, and volume, speed and parking data are collected from the main congestion points. The results showed that parking on the road causes the road capacity to decrease, with the lowest speed reaching 8.33 km/hour, the highest density reaching 144 vehicles/km, and the highest degree of saturation is 0.54 with service level C.

Abstract

Cold Paving Hot Mix Asbuton (CPHMA) Asbuton mixture consisting of aggregate, granular asphalt, rejuvenator and other added ingredients which are mixed hot cold paved. This product is an alternative that is very suitable for road construction in remote areas and small islands. where asphalt mixing plant (AMP) facilities are limited. The purpose of this study was to identify the effect of natural rubber (latex) on marshall characteristics in CPHMA mixtures. This study used the addition of natural rubber (latex) content of 10%, 15% and 20%. Samples were made of 15 briquettes consisting of 6 characteristic briquettes and 9 variation briquettes. The manufacture of briquettes refers to the Bina Marga General Specifications 2018. Sample testing is carried out using the marshall method. The test results show that the effect of adding natural rubber (latex) has no effect on the properties of the CPHMA mixture and causes the value of the mixture to decrease and natural rubber (latex) in any percentage does not affect the value of stability and durability.
