The relation of compression strength with modulus of rupture and UPV of concrete containing M sand as fine aggregate

The impact of manufacture sand on UPV, compression strength and modulus of rupture has been experimentally investigated and discussed in this paper. Concrete grade 30 (30Mpa) were produced with different percentage of M sand substitution ranging from 25%, 50%, 75% and 100% by volume were selected as concrete mix design in this project. The strength for different percentage of M-sand incorporation was measured by the destructive test which are compression strength test and modulus of rupture test and non�destructive test which is UPV test for curing ages of 90, 28 and 7 days. Furthermore, the highest compression strength of concrete and modulus of rupture was found on the 90th day containing a proportion of 75% of M-sand as a substitution for natural fine aggregate. A novel empirical equations 1 & 4 are proposed for the relation of compression strength with the modulus of rupture and UPV

Statistical overview on quality bus services in Klang Valley

Malaysia is one of the fastest grown country in Southeast Asia. Urban development in this country has a same issues should be address as developed countries around the world such as traffic congestion and increasing development area as well as population. Urban area in these countries is facing tremendous traffic congestion problem due to increasing of car ownership day by day. Therefore, there is an urge to study the current state of West Klang public buses in order to provide a thorough picture of its service ratings and performances this paper presents the statistical analysis of the stakeholder perception on the bus service for urban transportation in West Kuala Lumpur. The scope of work for this study is to investigate stakeholders’ views on bus service performance by did a survey in the west side of Klang Valley area only, which are and Puchong, Subang Jaya, Klang, Shah Alam, and Petaling Jaya. Several analyses have been conducted to identify the statistical analysis based on the data given by stakeholder.The result showed that, there are significant positive relationship between all attributes and bus performance. Result summary of hypotheses testing showed the positive relationship between variable. There are several issues should be improved to increase the quality of service for bus performance such as the on time performance buses, route service provided by operator and service coverage of bus. These are several issued have addressed by corresponding and users. Bus operator and government plays their roles tried to rectified all necessary issued and ensured that public opinion and user feedback would be heard.Feedback regarding level of service quality for bus performance should be conducted frequentl

An Exploration on the Developing of Expert System in Transport Engineering

This paper aims to determine the expert system developed from past research observations. This overview of expert system indicates the use of system which have slight affects on the results. Planning of research design enables a researcher to decide on what system it should be conducted. Two main components categorized for this paper are knowledge base obtained from previous study and a comparative study between the expert system to get a summary of the best inference engine, knowledge base, benefit and understanding

Creep-recovery behaviour of crumb rubber modified bitumen (CRMB) containing trans-polyoctenamer

The main objective of this study is to analyse the creep-recovery behaviour of crumb rubber modified bitumen (CRMB) and crumb rubber modified bitumen containing Trans-polyoctenamer (CRMB-TOR). Moreover, the effect of different stress levels to creep parameters, namely, non-recoverable compliance (Jnr) and per cent recoveries (% R) are also studied. The Multiple Stress Creep Recovery (MSCR) test performed by Dynamic Shear Rheometer (DSR) was executed at 1 s creep loading with 9 s recovery over the multiple stress levels ranged from 25 to 25,600 Pa. In this study, CRMB was prepared with different percentages of crumb rubber namely 4%, 8% and 12%. The CRMB-TOR was prepared by adding 4.5% of TOR (by weight of crumb rubber) to each CRMB blend. Adding crumb rubber in the bitumen shows desirable change in creep-recovery behaviour. Moreover, application of TOR to the CRMB seems to further improve the creep parameters. An increase in creep-recovery parameters (low Jnr and high % R) can significantly improve the properties of bituminous mixtures. Thus, pavement constructed with good creep-recovery parameters would increase the service life with better rutting resistance

Assessing stakeholder’s view for quality bus services in Kuala Lumpur

Malaysia will be one the developed countries in the next 10 years. Major cities such as Klang Valley will receive big impact on this development. Population and vehicle will growth as same as development year by year in especially in Klang Valley. The increase of vehicle in this country has caused a major problem in Klang Valley. The government has provided certain initiative to resolve this issue by implementation of Bus Network Revamp (BNR) in 2015. There is no comprehensive studies has conducted to evaluate the quality of bus in West Kelang Valley previously. The objective of this initiative is to reorganize and rearrange the existing bus service in Klang Valley in order to improve their service quality. this study was aimed to determine the of stakeholder’s view on the bus performance in West Klang Valley. 500 questionnaires have been distributed in targeted area in West Klang Valley such as Puchong, Subang Jaya, Klang, Shah Alam and Petaling Jaya. Specific criteria have been selected in order to determine the quality of bus service in these studies. Based on the result showed that, the overall quality of bus service in Puhong, Klang and Petaling Jaya have Medium qualityof bus service meanwhile Shah Alam and Subang Jaya have Good quality of bus service. Subang Jaya routes has received highest number of “Very Good” feedback from respondent compared with other routes. These studies only covered five main cities in West Klang Valley. Therefore, furthers studies in these area should be covered all routes in Klang Valley, as to provide a better comparison between quality of service of bus and stakeholders’ views on bus performance in West Klang Valley. There is few problems should encounter regarding public transport issues in Klang Valley. As a public service provider, feedback from passenger is important and all weakness should be address in future
