Nowadays a lot of modifications are taking place throughout the world to develop the existing highway materials to fulfill the demand of increased vehicles. People are at the trend to innovate something new that can do better than it was. Some material produce a good effect and enhance the strength as well as qualities of bitumen. On the other hand, some are responsible for the adverse on the bitumen. In saline areas like coastal regions, the salts play a significant role in the bituminous pavements. Water of sea nearly contains 3% sodium chloride, and evaporation of intake bodies of water has produced huge and extensive deposits of it. We can be economically benefited if salt is used as an admixture to bitumen. But we do not even know the impact, good or bad of the mixing of salt with bitumen. The objective of this paper to find out whether it is desirable or not taking various proportion salt with bitumen and doing the specified test of bitumen. It is observed from the laboratory test that the penetration and ductility values are gradually increased with increase of salt content. The flash point, fire point, and softening point value are stepwise reduced as a percentage of salt content increased. Moreover, it reduces the stability of roads. Mixing of salt to bitumen upgrades workability and it is beneficial in the economical point of view. Finally, moisture effect test on the bituminous mix with the GJRE-E Classification: FOR Code: 090599 EffectofSodiumChlorideonPropertiesofBitumen Strictly as per the compliance and regulations of: Global Journal of Researches in Engineering: E Civil And Structural Engineering Volume 19 Issue 1 Version 1.0 Year 2019 Type: Double Blind Peer Reviewed International Research Journal Publisher: Global Journals Inc.

After a cycle of management that began with President Luis Inácio Lula da Silva, the inauguration of Jair Bolsonaro bringing a new period of management in the Federative Republic of Brazil. In addition to macroeconomic issues and various other national interests, the new government will have to analyze the legacies and will have new challenges in the civil aviation sector. Using an evolutionary historical perspective, this article briefly points out some alternatives for the implementation of viable projects for the development of this important sector for the country’s development.

As of 2020, shipping companies will have to use low-sulphur fuels to comply with current international regulations set out in Annex VI of the MARPOL Agreement (regulations for the prevention of air pollution from ships), which will limit the maximum sulphur content in marine fuels to 0.5%. It is against this backdrop that natural gas (LNG) is being considered as one of the primary alternative fuels to enable compliance with this international regulation. Currently, there are 103 LNG-fuelled vessels in operation around the world and 97 on order. Car and passenger vessels make up the largest segment, accounting for 40 of the 103; none of these, however, is a high-speed (HSC) ropax vessel with capacity for both passengers and trucksi n open seas. HSC vessels are deployed in niche markets requiring high-speed propulsion engines (around 1,000 rpm) that can maintain service speeds. Existing LNG dual-fuel engines cannot be used to retrofit HSC vessels as they have been developed from a range of medium-speed engines (around 500-700 rpm) and they are heavier than those high-speed engines traditionally used by the HSC industry. This paper presents the innovative technology developed for the world’s first adaptation of a high-speed engine to LNG dual-fuel use by the shipping company Fred. Olsen S.A., within the GAINN4SHIP INNOVATION project.

Changes in the road environment of Tianjin were intended to speed up the traffic system and shift bicyclists to the metro, bus and car. The metro system was greatly expanded, along with a modernized bus fleet. App-based taxi services were also introduced. In 2007, travellers to the central area were intercepted to determine the starting point of their trip and their travel mode. The most time-efficient trips in 2007 were by bicycle (61%). These trips were re-enacted in 2017 using taxi and metro as it was no longer physically possible to replicate most of the original bicycle trips. Trips greater than 5 km in distance were somewhat faster by taxi than they were by bicycle, but overall, travel time by taxi was greater than by the bicycle for those same trips in 2007. A network analysis of road changes provides explanation why longer trips became more efficient while short trips became less efficient. Travel by metro alone was much longer than the other two methods, but the combination of app-based bicycles and metro would render this travel method the most efficient.

Industry 4.0 is a collective term including a number of automation, data exchange and manufacturing. It will create many kinds of innovative business model via customized design and marketing. From the supplier chain: purchasing, production controlling, incoming, production and shipping to the demand chain: ordering, logistics delivery, retail, and maintain service, it can integrate the all processes to be a value chain through computation, communication, controlling, collaboration and real time response. The quality requirements of all processes of the value chain would be much more transparent. As the demand chain, product and service will be required more accurate, speedy, reliable, safety, ecological, and environmental. As the supplier chain, the product and service will be required more easily to design, manufacture, change, transport, maintain, recycle and trace. Under the development of Industry 4.0, the entire value chain system will generate a large amount of data, including data related customers, data from suppliers and production, analysis of these data must apply SPC (statistical process control) and statistical techniques. Therefore, people in the value chain should strengthen the traditional quality management knowledge and skills, but also understand the development and application of ICT (information communication technology). The following are the relevant ICT knowledge and technologies of the sensing layer, the network layer, the application layer and value integration layer in the entire value chain system: (1) Sensing layer: SCADA (supervisory control and data acquisition), PLC (programmable logic controller), sensor equipments, Bar Code ID, RFID (radio frequency identification); (2) Network layer: basic network knowledge, basic knowledge of cloud computing; (3) Application layer: DBMS (database management system), MES (manufacture execution system), ERP (enterprise resource planning), PLM (product lifecycle management), CRM (customer relationship management), SCM (supplier chain management); (4) Value integration layer: hardware and software system integration engineering. This article try to summarize the ICT related knowledge should be owned by the participants of all the processes of the value chain.

: Among the fast growing states in the USA, the States of Washington and Oregon have enacted legislative land use and transportation concurrency/balancing planning policies for orderly urban growth management since 1990 and 1991, respectively. Regional or urban travel demand forecasting models play an instrumental role in implementing the Washington GMA (Growth Management Act) and the Oregon TPR (Transportation Planning Rule). Both program- and project-level modeling approaches to urban land use/transportation system management are evaluated through the selected cities in Washington and Oregon.
