Abstract

This paper discusses traffic performance under major and disruption events on the road network. Traffic on the road network is modelled based on a microsimulation model by considering conditions without disruption, with disruption, and with disruption accompanied by the mitigation schemes. The simulation model used in this paper models the driving behaviour at the micro level that can be used to simulate interactions between vehicles and traffic performance in response to changes in road capacity due to disruption. The model is tested on a road network with significant sports events and potential natural disasters. Traffic flow is estimated based on information from previous events. The results of the microsimulation modelling show that the disruption scenario can reduce road network performance by up to 43%, with total delays that can increase up to five times. In addition, the mitigation schemes to reduce the disruption contribute to maintaining good traffic performance. This paper's framework can potentially be used to assess the impact of traffic disruptions during significant events. Furthermore, it can evaluate alternative strategies to overcome the disruption.

Abstract

High plasticity clay (CH) has poor material characteristics, such as considerable shrinkage due to high plasticity, so soil improvement is needed, for example, using cement and coal waste (bottom ash and fly ash, BAFA). The purpose of adding cement and BAFA type C is to see the effect on changes in soil CBR values. Variations in BAFA addition are 4%, 8%, 12% and 16% and PCC cement 3% and 5%. The percentage of bottom ash content to fly ash in BAFA is 2:1. Based on the test results, an increase in the CBR bearing capacity value was seen from 0.78% in the original soil to 18% in samples with a mixture of 5% cement and 16% BAFA with 7 days of curing. The CBR sample S5-B16-C7 is the largest value of all sample variations. The increase in the CBR value is huge from 0,78% to 18.73% This value proves that the combination of mixtures can effectively increase soil-bearing capacity. Based on microscopic testing of CBR samples, it can be seen that the higher the BAFA and Cement content, the rougher and paler the changes in the sample structure are. Conversely, the sample structure is smoother at the lowest BAFA content and cement content, and the sample colour is brighter, approaching the original soil colour. The results of this study indicate that BAFA can be used as pavement materials and provide a solution to the environmental impact of industrial waste.

Abstract

Ground Granulate Blast Furnace Slag (GGBFS) is a by-product or non-metallic waste from the iron and steel production process. GGBFS is currently widely applied as an additive to mortar mixtures because it has pozzolanic properties. It can also be used as a material for stabilizing subgrade soil that is not included in the technical requirements for road pavement. GGBFS is a geopolymer material with NaOH and Na2SiO3 as an alkali activator to produce a solid polymer bond like cement. The concentration of 10 M NaOH used is with a solution ratio of 2.0 (Na2SiO3 to NaOH), variations in GGBFS content of 0% and 20%, and variations in S/L content (GGBFS to activator) of 1/2 and 1/2.5; which is mixed with the original soil to make a sample of an Unconfined Compression Test (UCT), with the curing of the UCT test specimens carried out for 0, 7, 14, and 28 days. From the test results, the original soil sample is of the OH soil type. The results of UCT testing of original soil samples without stabilization with a curing time of 28 days were 1.59 kg/cm2, while the stabilized soil sample (80% soil, 20% GGBFS, alkali activator S/L (1/2.5)) was 29.386 kg/cm2. The results of UCT testing showed a significant increase in soil strength values ​​, so geopolymers with GGBFS and (NaOH; Na2SiO3) materials can be used as soil stabilization materials like Portland cement.

Abstract

The use of geoporous asphalt is an environmentally friendly alternative because it is made using waste and in its application it can help water absorption into the soil.. The waste used to manufacture porous asphalt in this study was fly ash (FA) and rice husk ash (AS). Fly ash has pozzolanic properties, and rice husk ash contains carbon (C) and silica elements, which function as adhesives. Using goepore asphalt on the shoulder of the road can be an alternative to faster water absorption without damaging the pavement layer underneath. This study aimed to obtain a mixture variation between FA and AS as fillers for optimal mixture variation in manufacturing porous asphalt. Comparison of filler mixtures in manufacturing test objects with FA and AS mixtures variations using the filler substitution method in the manufacture of regular asphalt, namely cement. In the variation of normal asphalt mixture content, the cement used is 2%  from the weight of asphalt substituted with a mixture of FA and AS for the manufacture of geoporous asphalt test specimens with variations in filler mixture con. This study used 60/70 penetration asphalt with an optimum asphalt content (KAO) of 4.6%. From the test results, it was found that the most optimum mixture content variation was in a mixture of 100% AS: 0% FA with a stability value of 729.556 kg, a flow value of 5.37 mm, a VIM (Void In the Mix) value of 20.86%, a Marshall Quotient (MQ) of 135.82 kg/mm, and a permeability coefficient value of 0.447 cm/sec. The Marshall parameter values and permeability coefficient values  meet the AAPA 2004 specifications, namely 500 kg stability, 2-6 mm flow value, 18-25% VIM value, 400 kg/mm MQ, and a permeability coefficient of 0.1-0.5 cm/sec.

Abstract

The factory has produced solid natural rubber asphalt (AKAP PG 76) and has received support for its implementation by the government. The application of materials in road works at the Directorate General of Highways refers to the Special Specification for Solid Natural Rubber Asphalt (SKh-2.M.04). However, the use of AKAP PG-76 is still limited or only used in national road projects. One of the contributing factors is its relatively high price. This study will evaluate the comparison of price and quality produced. This study aims to compare the characteristics of AC-WC asphalt concrete mixtures using PEN 60/70 asphalt and AKAP PG-76 asphalt. Before the Marshall test, samples with five variations of asphalt content were soaked at 60 oC and 80 oC to achieve optimal asphalt content. The advantages and resistance of asphalt pavement to extreme weather can be seen from the residual strength index. The residual strength index was obtained from the Marshall test comparison of samples with optimal asphalt content soaked for 30 minutes and 24 hours at temperatures of 60 oC and 80 oC. This study found that the asphalt concrete mixture using solid natural rubber (AKAP PG 76) and PEN 60/70 asphalt showed good resistance to extreme weather conditions. However, AKAP PG 76 is better because it has higher Marshall stability and can withstand scorching weather.

Abstract

One of the elements in the bridge structure is prestressed concrete. Bridge performance evaluation is needed to determine the repair method for the element if there is a potential for construction failure. This study aims to design a prestressed concrete bridge using midas Civil software. The bridge structure is modelled along with the working loads, which include Dead Load (DL), Super Impose Dead Load (SIDL), and earthquake loads based on SNI 1725:2016 and SNI 2833:2016. This study uses a non-linear time history analysis method (non-linear time history analysis), and design parameters are taken from the NCHRP 44 and 949 references. Midas Civi software is used for the analysis. Design parameters include concrete material strain, steel reinforcement, and drift on lateral retaining elements (bridge pillars) composed of reinforced concrete material. The Terbanggi Besar Interchange Bridge (IC) STA. 139+925 on the Bakauheni – Terbanggi Besar Toll Road in Lampung Province is used as the focus of the study. This study identifies the limits of bridge structural damage during the post-earthquake to determine the performance of the bridge structure. Seven pairs of ground motions were installed, representing the conditions at the bridge site. The results of this study indicate that the performance level of the Terbanggi Besar IC Bridge Structure is at the whole operational performance level. This level describes the condition after receiving the earthquake load. The bridge condition can operate optimally, and the structure is still elastic. This study suggests using similar methods on other bridges to hinder bridge performance and anticipate building failure.
