The social and economic impacts of e-hailing application in Malaysia: A review

E-hailing is a service that allows users to book a journey online and provides a platform for users to interact with E-hailing companies. E-hailing service in Malaysia was launched in January 2018. Growing population and rising migration from rural to urban areas have put a strain on quality of life for Malaysia's population. The service is available in Malaysia. It has so far had success. E-hailing services have become more popular than traditional taxis for a variety of reasons. Customers are likely to seek out these providers' services as long as they pay close attention to their needs, solicit feedback often, and improve the quality of the services they give. Mobile applications developed by e-hailing businesses have had a significant influence on the taxi industry and public transportation in the last few years. Experts examined the impact of e-Hailing services on consumers, drivers and the public economy. Economics service created a lot of work prospects for drivers. Taxi industry struggling to keep up with E-Hailing system which put it under threat, as it cuts in taxi industry's profits. All e-hailing drivers must now obtain Public Service Vehicle (PSV) permits, but they complained that the regulations were too strict. Many of these driver-partners used E-hailing as a method to earn supplemental money in addition to driving. In the next several years, the way people move around in cities is anticipated to alter drastically. The conventional marketplace is being replaced by the online transaction as a method of conducting business. E-hailing in Malaysia today, as an alternative to private and public transportation, may be summed up by pointing out its increasing use

Statistical Analysis of Stone Mastic Asphalt Incorporating Kenaf Fibre

Stone mastic asphalt consists of two components of coarse aggregate and bitumen-filled mortar (bituminous blend, filler, and stabilizing additives like cellulosic or mineral fibers). Such a form of hot mix asphalt (SMA) was first developed in Germany in the mid-1960s to cope with corrosion and ribbed wheel destruction. The mixture was then known as stone mastic asphalt, which was not only immune to ribbed wheels but also has strong resistance against rutting. One of the most significant problems when constructing the stone mastic asphalt pavement is permanent deformation. By a load of traffic and the strain of the tires, much of the irreversible deformation happens in the ground. According to a previous study, researchers have stated that the kenaf fiber's physical strength and thermal characteristics are superior compared to other forms of natural fiber polymer composites, and therefore deemed a desirable applicant for elevated-performance natural fiber composite materials. Thus, the aim of this study is to assess the mechanical performance of stone mastic asphalt incorporating kenaf fiber by developing a regression model. A set of data of SMA mixture incorporating various percentages of kenaf fiber were assessed through statistical analysis in Minitab 19 by using the resilient modulus as the dependant variable in the first model and the accumulated strain from the dynamic creep test as the dependant variable in the second model. The regression models showed a positive impact of kenaf fiber as an additive in the SMA mixture. For more future studies, it is recommended to analyze the effect of the various proportions of kenaf fiber with bitumen modification towards stone mastic asphalt performance that will render the satisfactory performance of SMA during service

The usage of recycled glass in hot mix asphalt: A review

Waste material has been defined as any type of material by-product of human or industrial activity that has no residual value. The elimination of waste glass in landfills become a serious challenging task which several countries look out on it on all sides of the world. Reusing of glass waste for road construction is a sustainable solution to environmental and ecological problems. Reusing of glass waste will reduce the construction cost of pavement, reduce the landfill cost. This study has done to review the overall performance of asphalt concrete blend, in which several exceptional combinations of aggregate is replaced with various proportions of crashed glass. This review is discussed some main properties of asphalt mixture, such as stability and flow. The results shown that the stability was higher than that of the glass waste samples and decreasing as the glass waste increasing. In general, the research displays that using glass waste in asphalt mixture is acceptable
