Abstract

The use of waste crumb rubber tire as an additive in asphalt has been widely practiced in several countries in the world, which aims to improve the characteristics of asphalt mixtures such as porous asphalt. The purpose of this study was to determine the effect of used waste tire rubber powder as an additive in asphalt on the characteristics of porous asphalt mixture using aggregate from stone crusher machine in Loli, Palu city, Central Sulawesi Province. This research was conducted at the Transportation and Highway Laboratory, Tadulako University.This research used several percentages of used waste crumb rubber tire as follows: 0.025%, 0.050%, 0.075%, 0.10% of the aggregate weight in the mixtures (1200 grams). Aggregate composition determination in mixture using Method by sieve.  Optimum Asphalt Content determination using Marshall Method. The results of this research found that the Stability and density value of the mixtures tend to increase at the content of 0.025% - 0,075% used waste crumb rubber tire. The results also found that the maximum stability and maximum density were reached at the Optimum Asphalt Content and the used waste crumb rubber tires content were 0.58% and 0.075%.

Abstract

Tondo 1 permanent housing is intended for residents affected by the earthquake and tsunami on 28 September 2018. Furthermore, Tondo 1 permanent housing is now inhabited by people from various areas such as Petobo, Mamboro, Balaroa, Talise, and Tondo Villages. The rapid population growth in the tondo village after the relocation resulted in increased movements in the tondo village due to a large number of trips. This affects the trip generation of people who travel from their homes to the Central Business District (CBD) to carry out their daily activities. This study aims to determine the community's characteristics and model the trip generation in Tondo 1 permanent housing. This study used the multiple linear regression method. Based on the calculation, two variables affect the trip: the number of working family members (X2) and the number of vehicle ownership (X5). Therefore, the analysis model of the trip generation of survivors at Tondo 1 permanent housing area is obtained as follows: Y = 1.766 + 0.325 X2 + 0.271 X5.

Abstract

Street of Karanja Lembah is a provincial road linking Palu City and Sigi Regency. After a visual survey, the road has suffered a lot of damage, especially on its surface. The purpose of this study was to determine the pavement condition values based on the Pavement Condition Index (PCI) method and the Present Serviceability Index (PSI) method, as well as to determine the type of road handling based on the PCI and PSI values obtained on these roads. The PCI method is carried out directly by dividing the road into several segments called segment units, then recording the type of damage, the dimensions of the damage, and the severity of the damage for each type of damage. In research using the PSI method, the PSI value was calculated using IRI (International Roughness Index) data obtained from the Highways Service of Central Sulawesi Province. From the results of the analysis, it was obtained that the average PCI value for Jalan Karaja Lembah was 79.95% with a "very good" pavement condition, while the average PSI value for Jalan Karaja Lembah was 2.13% with a pavement condition "moderate". For the right type of handling for the PSI and PCI methods, namely the type of periodic maintenance.
