3rd October to 5th October, 2017
Institute of Road Engineering in Indonesia (IRE) and NILIM have carried out joint researchof road and traffic fields.
The mid-term Conference of IRE and NILIM Joint Research was held in Tsukuba, Japan
by NILIM, Japan and IRE, Indonesia on 3rd October to 5th October 2017.
The activities of The Conference are as follows;
1) The mid-term Conference (The main conference)ⅰ) Keynote speech by Director-General of NILIM
and Head Representative of ARD*1 MPWH*2 of Indonesiaⅱ) Plenary session by researchers of 5 fields
2) Technical visitⅰ) Site visit on trial construction of AsButon Guss asphaltⅱ) Open house of facilities of NILIM and PWRIⅲ) Site visit on Ohashi Junctionⅳ) Site visit on Construction site of Tokyo Outer Ring Road(*1) ARD : Agency for Research and Development(*2) MPWH : Ministry of Public Work and Housing
Total of 53 people, including six researchers from the IRE, participated the conference. It
includes ordinary participants from outside of NILIM and PWRI.
1. The mid-term Conference (The main conference)
On 4th October 2017, The main conference was held at NILIM, in Tsukuba city.
Until now, the research has been conducted in each field individually, for example,workshops were held in each field.
In this conference, Indonesian researchers and Japanese researchers of 5 fields assembled in
the same place. They conducted the cross-sectoral presentation and discussion.
ⅰ) Keynote speech by Director-General of NILIM and Head Representative of ARD MPWH ofIndonesia
In morning session, keynote speeches held by Dr. Fujita, Director-General of NILIM, and Dr.
Madi Hermadi, Head Representative of ARD MPWH of Indonesia.
Dr. Fujita spoke aboutmain function of NILIM, they are: "Conducting research andpreparing technology standards", "Supporting disaster-response activities", "Technologyconsulting and technological capability enhancing", "Research coordinator". Moreover, hespoke about new technology and innovation, the importance for a greater effect ofinfrastructure, and the application to maintenance of infrastructure, as the prospects for thefuture.
Dr. Madi Hermadi spoke that the government of Indonesia is aware of the importance ofinfrastructure as the foundation of development in various fields, Indonesia has manydemand of infrastructure, technologies are developing rapidly, but technical guidelines etc.
are not yet available. Moreover, he said, this cooperation should be maintained and developed.

In afternoon session, research progress was reported by researchers of 5 fields: "Road-sidestation" "Traffic Data Collection" "Road Environment" "Pavement" "Tunnel & UndergroundStructures".
《Outlines of presentations》①Road-side station・Researchers developed the planning guideline for planning and designing road-side station(in Indonesia "RosSita") that is incorporated the concept of Michi-no-Eki in Japan.
・In Bali, "RosSita" will open in 2018.
②Traffic Data Collection
・Inductive Loops & Piezoelectric Sensor (LPS), the conventional traffic volume measuring
equipment in Indonesia, have some problems.
・ Researchers studied the application of Image Processing Technology (IPT) to traffic
counting, as a technology to compensate for problems of LPS.
・Researchers got the knowledge about applicability and optimum camera settings of IPT.
③Road Environment
・Currently, motorcycle is the main transport in Indonesia.
・Estimation results of change of CO2 emissions when the road traffic mode was converted inIndonesia and Japan.

・Researchers confirmed that motorcycles have less CO2 emissions and the effectiveness asenvironmentally friendly road transport mode. They confirmed that by the field test on CO2emissions of motorcycle and 4-wheel vehicle.
④Pavement
・The draft of "Guideline of AsButon Guss asphalt" was developed. AsButon is Indonesiannatural rock Asphalt, and AsButon Guss asphalt pavement has the function as water-proofing
layer on the steel deck.
・Researchers are planning the trial construction of Asbuton Guss asphalt on Steel Deck inIndonesia.
⑤Tunnel & Underground Structures
・"Technical guideline on Auxiliary method for mountain tunnel" was developed. It is neededto construct the tunnel in poor ground condition.

Participants of the mid-term conference2. Technical visit
On 3rd & 5th October 2017, 4 technical visits were conducted as sub events of the conference.
ⅰ) Site visit on trial construction of AsButon Guss asphalt
On 3rd October 2017, participants visited the trial construction of AsButon Guss asphalt
mixture by a private pavement company.
ⅱ) Open house of facilities of NILIM and PWRI
On 3rd October 2017, participants visited experimental facilities in site of NILIM and PWRI,"The test course", "Three-dimensional large-scale shaking table", "Verification facility of nondestructive testing technology for bridge", "Oceanic and coastal experiment facility".

testing technology for bridgeⅲ) Site visit on Ohashi Junction
On 5th October 2017, participants visited Ohashi Junction which connects “Central CircularRoute” and “Metropolitan Expressway Route 3”.
There is about 70m difference in height between 2 routes, therefore Ohashi Junction connects
2 routes by way of 2 loops for ups and downs (there are 4 loops as total of climb and down).
At first, participants drove through the Junction by bus, when they observed facilities forsafety driving, such as color-coded guidance.
Next, staffs of Metropolitan Expressway Company Limited explained uniqueness andconstruction technology of Ohashi Junction and Yamate tunnel to participants.
In addition, participants visited the ventilation facility and ecological restoration spaces
which is set up with the Junction.
ⅳ) Site visit on Construction site of Tokyo Outer Ring Road
On 5th October 2017, participants visited the construction site of Tomei Junction of Tokyo
outer ring road. In February 2017, 2 shield tunnel machines to each tube started from thissite.
At First, the explanation of construction technology was conducted by staffs of MLIT's Tokyo
Outer Ring Road office, NEXCO EAST and NEXCO CENTRAL.
Next, participants observed construction facilities, such as shield pit, stockyard of segment
and stockyard of soil which had discharged from shield machines.
In addition, staffs explained to participants that they are managing the motion ofconstruction vehicles by GPS, for the prevention of traffic jam in neighboring roads.

3. Reference (History of the Cooperation)
The National Institute for Land and Infrastructure Management (NILIM) and the Instituteof Road Engineering (IRE) renewed cooperation arrangement in Indonesia, February 2014.
Under this agreement, NILIM and IRE have been continually sharing research information
by jointly holding technical seminars and exchanging researchers to strengthen links between
both research institutes and to form international human networks, thereby to contribute thegrowth of Indonesia.
