2016. Taking this occasion to visit Japan, REAAA is planning to hold the Business Forum (“BF”) in Tokyoon Tuesday, November 1, 2016, to provide the opportunity to connect Business-to-Business and Governmentto-Business in road engineering. REAAA organized the BF twice: the 1st BF took place in Bali, Indonesia inApril, 2014 and the 2nd was held in Sydney, Australia in October, 2014. The theme of the 3rd BF is “NewTechnologies on Road Construction.” Specialists from various fields will make presentations about their newtechnologies at BF.
It is expected to exchange road engineering information and to enhance relationship among business persons,institutions, and companies of REAAA member countries.

REAAA Business Forum Presenters and Abstracts“History and Pavement Technology of the porous asphalt mixture”
Institute of Research and Development, Taisei Rotec Corp.
Kazunari HIRAKAWA
Japan Road Constructors Association technical committee had edited the pavement technology inJapan aiming at Tokyo Olympic in 2020, and published this as “O･MO･TE･NA･SHI”
Technology Provide the Comfort and Safety from the Road Pavement for the People Visitingfrom the World”. In this Business Forum, focusing on Porous asphalt mixture, its history andtechnology will be reported. In addition, solar ray reflective pavement and water retaining
pavement, those are based on the porous asphalt mixture, will be introduced as advancedtechnology for the future.

Steel Structure Engineering Sector, JFE Engineering Corp.
Tooru WATABIKI
Traffic jams in urban areas cause huge economic losses and become one of the most crucial social
issues almost all over the world. This presentation demonstrates how the state-of-the-arts steel
structure technologies can be effective to construct viaducts and provide grade separations inurban areas to solve the social issue. The virtues derived from the steel structures enable toshorten the site construction periods and minimize the impacts to local environments and theexisting traffic. The presentation also shows the steel structures with newly developed treatments
can prolong the service life of infrastructures as well as minimize the life cycle cost resulting inproviding “high quality infrastructures” promoted by the Japanese government.

Naoki NAGAMOTO
In order to reduce future maintenance work, the Non-metal Bridge was developed. It is concretestructure, but completely eliminated the use of steel members such as steel reinforcements andprestressing steel. Aramid FRP rods are used as prestressing tendons. To eliminate the need forshear reinforcement, the Butterfly web structure was applied to it. To investigate this structure,
several experiments were carried out such as wheel loading test and its structural performanceswere verified.
Based on those results, the actual pilot bridge was built and has been used as a part of atemporally construction road with full-time monitoring system.

International Affairs Div., Technical Consulting Dept., Metropolitan Expressway Co., Ltd.
Mitsuhiro NARISAWA
Since its first opening of 50 years ago, the Metropolitan Expressway Company has beenaddressing protection of expressway structures as a toll road operator in Japan and has developed
technologies to treat unexpected types of damages and to manage unmanageable amount ofmaintenance works as well.
After a brief introduction of company profile, background of maintenance, and future
maintenance plan, ‘InfraDoctor’, which is a newly developed system, utilizing GIS and point
cloud data to improve efficiency and accuracy of maintenance works on road and structures,
would be introduced.

REAAA Business Forum Presenters and Abstracts“Utilization of Big Data for Road Planning and Management in Japan”
Road Department, Pacific Consultants Co., Ltd.
Sungjoon HONG
Demand for the use of big data is increasing dramatically. Various kinds of data sources areavailable, and commercial data providers are increasing in Japan. Big data is also essential forroad and transport planning and management these days, because it provides information ofwhich the measurement was impossible before, such as origin, destination, and route of individual
trips, driving behavior including speed, acceleration, and deceleration. This presentation shows
examples of the use of big data in the road planning and management field in Japan including thedata collected by ETC 2.0 vehicles, trucks, mobile phones, driving recorders, etc.

Road is indispensable social infrastructure to support livable economy. The sustainable funding
scheme to build and maintain the road is critical issue. Currently in the world economy, Road
User Charging is getting popular as social mechanism to impose levy on the motorist to use roads,and classified into four categories in terms of policy goals; tolling to reimburse the construction
cost, congestion charging to manage traffic demand, heavy truck charging to secure operation andmaintenance cost for damaged roads, and external diseconomies charging to reduce negativeexternality such as air pollution.

Michihiko YUSA／Shinji HARA
For efficient and safe traffic, it is important to provide traffic information for drivers, road
operators and so on. To realize it, valuable and actual information are needed. But there are many
sensors on the road, for example CCTVs, emergency telephones, seismometers. So for smoothprocessing, big data technology are needed. And also from point of BCP views, disaster recovery
system is very important. Thanks to this system, operators can continue their operation even if
huge disaster happen. This presentation shows sophisticated traffic management system that has
those functions and contributes to efficient and safe traffic environment.
