Abstract

The accuracy of predicting the elastic modulus of asphalt mixtures is crucial for analyzing pavement structure performance. This prediction impacts pavement responses, including tensile strain below the surface layer and compressive strain below the subgrade. Calculating equivalent standard axle loads (ESALs), specifically ESAL 4 and ESAL 5, is essential for determining pavement thickness. To ensure that flexible pavement provides safe and comfortable service, it is important to design the pavement structure to meet the planned service life. The pavement thickness was calculated using the 2017 manual pavement design method, followed by analysis with the Asphalt Institute method to predict load repetitions leading to potential road damage, such as fatigue cracking and permanent deformation. This research, a quantitative descriptive study with a case study approach, was conducted on HM. Yasin Limpo Road in Gowa Regency. The results indicated pavement layer thicknesses of 4 cm for AC-WC, 6 cm for AC-BC, 16 cm for AC-Base, and 20 cm for Class A subbase. The tensile strain value was 0.0001932 kilopascals, with load repetitions amounting to 24,324,108 ESALs, while the compressive strain was 0.0003511 kilopascals, with load repetitions of 39,924,439 ESALs.

Abstract

Makassar City is experiencing the same struggle with other big cities, namely the problem of urban transportation. The level of vehicle movement in Makassar City is quite high as a result, causing congestion in the downtown area and in the suburbs. Water transportation media cannot be separated from the origin of the transportation system above, namely the activity in the river circulation area so that it has the potential to be developed, this study analyzes the river route as a water transportation network into Makassar City transportation. Increasing the use of water transportation routes to generate social activities and a form of transportation system used for the transportation of goods and passengers through water. The advantages of river or canal transportation means that it is cheap, easy, relatively safe, the carrying capacity can be high in sync using the culture of its use, simple technology. The main weakness comes from river transportation, which means slow movement and many areas that are not traversed by commercial shipping channels.

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

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.

Abstract

This deceleration will affect the traffic flow in the same direction, this turning movement will cause high traffic volume, lower vehicle speeds, and higher density on the road section. The purpose of the study was to determine the performance of U-Turns and the level of road service equipped with U-Turn facilities, measure the average travel time of vehicles doing U-Turns, the speed of vehicles when doing U-Turns and the length of the queue doing U-Turn activities. To achieve these objectives, the PKJI 2023 method was used. From the results of the study, it was obtained that the Performance of the Road Section on Jalan Sultan Alauddin was 2640.25 skr/hour for traffic volume towards Gowa and 2881.50 skr/hour for traffic volume towards Makassar, for capacity with a degree of saturation of 0.77 for the Makassar - Gowa direction and 0.84 for the Gowa - Makassar direction. The conclusion of the research results shows that the Performance of Jalan Sultan Alauddin, Makassar City based on PKJI 2023 is 2465 skr/hour for Opening 1 and 2762 skr/hour for opening 2 and 2475 skr/hour for opening 2 for capacity with a degree of saturation of 0.72 for Opening 1 and 0.81 for Opening 2 and 0.73 for Opening 3.
