Abstract

Asphalt concrete-wearing cource (AC-WC) pavement is the layer that directly in contact with vehicle tires. One that affects the performance of asphalt concrete is compaction. Optimal compaction can be met if the temperature in the compaction is carried on at a good temperature and in accordance with the specifications. The purpose of this study was to determine the compaction temperature workability best value on asphalt concrete wearing cource (AC-WC) pavement.  Tests were conducted on the condition of optimum bitumen content by 8 (eight) wide solidification temperature variation which were at the temperature of 70 ± 1˚C, 80 ± 1°C, 90 ± 1°C, 100 ± 1°C, 110 ± 1°C, 120 ± 1˚C, 130 ±1°C, and 140 ± 1°C. Testing was conducted by using the Marshall test instrument as substitutes for gyratory devices. Porosity measurements performed on Marshall blow mix of 2 × 5, 2 × 10, 2 × 20, 2 × 40, 2 × 60 and 2 × 75. Based on the equations of relationship between the logarithm of the number of gyratory rotation and porosity then the intercept value can be obtained which was then used to calculate workability index (WI) of the compaction temperature variations.  The result showed that all of them do not show good compaction workability value, because its value is less than 6. However, from the eight variations of the solidification temperature of solidification temperature of 130 ± 1 shows the best workability with WI = 4.031

Abstract

Utilizing industrial waste materials containing pozolanic compounds has been widely investigated for cement replacement. Fly ash and microsilica are materials having significant pozolanic compounds and can be used to create ternary cementitious system. Slump of fresh concrete, porosity and compressive strength of hardened concrete were parametric study investigated in this study of ternary cementitious system.  Three types of concrete mixtures, i.e. concrete mixture using original Portland cement (OPC) as normal concrete, OPC-fly ash-microslica without superplasticiser, and OPC-fly ash-microslica with additional superplasticiser have been investigated. Fresh concrete using fly ash and microsilica demonstrated having higher slump and lower porosity than normal concrete. Compressive strength of concrete using fly ash and microsilica were higher than normal concrete. Utilizing fly ash and microsilica as ternary cementitious system was found to have significant effect on compressive strength and porosity of hardened concrete.

Abstract

Nowadays, students are less interested in using public transportation to the University of Tadulako.One reason is the travel time to arrive on campus can not be predicted. This study aims to determine the characteristics of urban transport users in serving the student travel, especially in Tadulako University.  The researc were conducted using descriptive method. The research was carried on by distributing questionnaires to 131 respondents. The respondents are the city transport users who travel to Tadulako University. The results of the research and analysis shows that the ease of getting public transportation to travel to and from the University of Tadulako classified as difficult, so users should walk or using the motorcycle taxi (ojek) to get to the waiting place for public transportation. There are areas frequented by the public transportation so that users can negotiate several times and there are also certain regions where users can only do 1 time negotiations within the same time frame. The uncertainty of travel routes makes the travel time of user to the destination is unpredictable.

Abstract

One of the few supermakets in Palu city which considerably crowded is Grand Hero Supermarket. This Supermarket was located on the Basuki Rahmat street. Because this road is an arterial road with highly traffic volume at certain hours, so the Grand Hero Supermarket activity will affect the performance of the road. At peak hours, many vehicles are in and out from the supermaket, disrupting theperformance of BasukiRahmat road. The aim of this research is to understand the existing condition of the Basuki Rahmat street performance with or without the activity of Grand Hero Supermaket. This research was conducted by surveying the volume of the street, side friction and travel time. The survey was carried on Wednesday 04-06-2015 and Saturday 6-06 2015. The analysis was conducted by using Manual Kapasitas Jalan Indonesia 1997 method. The results show that the performance of JalanBasuki Rahmat with no Grand Hero Supermarket’s activity has a degree of saturation 0.35. Grand Hero Supermarket with activity would increase the degree of saturation that is 0.43 that increases 22.86%. The speed of light vehicles by MKJI is  42.84 km / h. With the Grand Hero Supermarket activity, the speed of light vehicle decreased from 27.76 km/ h to 23.74 km / h or there are speed reductions of 14.49%. The level of service with the Grand Hero Supermarket activity was at B condition with DS rate of 0,43

Abstract

Bridge is one of the most important transportation infrastructures that joining two side of highway thus the bridge is highly needed. To design a bridge geotechnical and hydrological data is crucial as well as characteristic of the river. In the case if a bridge were designed without acurately determine the 50 year return period of flood, then the bridge possibly  are not save against real flood that may occur. Thus the abutment has to be redesign and retrofitted. Redesign is important to fullfill requirement of high of free space superstructure if the maximum flood occur. Redesign conducted by adding 1,6 m high of the abutment. Controlling stabilities of the abutment i.e: shear and overturning were done. Retrofitting was applied by adding longitudinal and transversal reinforcement with the same dimension and space especially at the joint of transversal reinforcement, transversal reinforcement space reduced to half of its normal space. Longitudinal reinforcement applied was D19-150 and the transversal reinforcement was ᴓ12-100. To connect the fresh concrete and existing concrete applied material were epoxy resin based produced by PT. SIKA Nusa Pratama SIKADUR®732.
