1-1. The theme for this time WS
In this 7th Joint Workshop, picked up six themes focused on;
1) Road Noise
2) Asphalt Concrete Pavement
3) Maintenance and Seismic Design for Road Tunnel
4) Maintenance of Port Facilities
5) Protective Coating and Weathering Test
6) ITS and Traffic Safety

The 7th Joint Workshop

1-2. Outline of Technical Session
1) Road NoiseJapan side presented the road traffic noise prediction andthe survey to understand existing conditions in Viet Namand Vietnam side presented the noise standard along theroads, the technical guidance of noise barriers and theenvironmental quality standards in road tunnel.
In the discussion, Japan side introduced ASJ model as a
useful prediction model for road traffic noise andexplained that the accuracy of this prediction need theimprovement reflecting Vietnamese situations. Vietnam
side showed an interest in testing and installing noisebarriers.
Both sides agree to cooperate on the research as follows;(1) research on Japanese basic standards to establish roadtraffic noise standards in Viet Nam, (2) research on noisebarriers.
2) Asphalt Concrete Pavement
On this session, both sides discussed and exchanged
information about 4topics as followinga) Deterioration, solution to improve the design andconstruction quality, and maintenance of asphalt concretepavementb) Recycling asphalt concrete pavementc) Materials, structure of asphalt concrete pavementd) Methods to checking, testing and assessing thebitumen quality and asphalt concrete pavement.
Finally, both sides concluded to have further research
about the following issues.
a)Solutions to improve asphalt concrete pavement quality
in Viet Nam;b)Methods of checking, testing and assessing the bitumen
quality and asphalt concrete pavement in order toimprove mix design and quality control on site;c)Japan side will help Vietnam side to further research on
recycling technologies in Japan;d)Asphalt concrete pavement maintenance and repair
technologies.

3) Maintenance and Seismic Design for Road Tunnel
Current situations on road tunnel technologies in Vietnamand Japan, including maintenance and seismic design,
were presented and discussed. Also, exchange of views on
basic concepts and methods of road tunnel inspection
were conducted. As a result, ITST would make up thedraft of inspection manual, technically supported byPWRI.
4) Maintenance of Port Facilities
For this topic, Japan side has presented 4 reports andITST has presented 2 reports. Both sides have discussed
the contents of a draft TCVN for rehabilitation andmaintenance of port facilities, which has been developedby ITST.
In the meeting, both sides have shared recognition on theimportance of considering the feasibility of the draft
TCVN in the actual situation and also have discussed how
to effectively improve the draft.
For the above-mentioned purpose, NILIM and ITST haveagreed to continue to work together.
5) Protective Coating and Weathering Test
Japan side gave a presentation on product specificationsof the steel protective coating in Japan and also reported
interim results of the collaborative weathering tests. From
Vietnam side, presentations on effect of mica mineral incoal tar-epoxy enamel, quality control of the steel
protective coating in Vietnam and traffic paint removers
in Vietnam were given. As a result of discussions basedon the above presentations, both sides have agreed asfollows: PWRI continues making a draft guideline of steel
protective coating in Vietnam including re-painting
techniques, ITST and PWRI expand the collaborative
natural weathering tests in Vietnam, Japan side provides adraft manual of paint remover suited to needs andconditions in Vietnam and ITST suggests on application
strategy for technology authentication and dissemination.

6) ITS and Traffic Safety
NILIM introduced the ITS Spot services and reported thepolicies for traffic safety, and ITCT reported the situationof traffic accidents, traffic control, and management ofroad infrastructure in Vietnam.
NILIM recommended that Vietnam deploy policies in theway which is line with the actual situation in the country
with referring Japanese cases, instead of applying
Japanese cases as they are.
ITCT requested NILIM to introduce preceding cases inJapan, and we agreed on that NILIM and ITCT willcontinue to exchange information.
It was decided that the maintenance of ITS infrastructure,operation, evaluation will be discussed in the next WS.

1-3. Reference (History of the Cooperation)
This cooperation was kicked off at an occasion of the visiting of ITST at NILIM inTSUKUBA, May in 2010 with Vice Minister of MoT, Vietnam, when both institutes agreed tothe Memorandum of the cooperation in the future scope, which means young and middle
researchers be involved in the cooperation in order to keep communication continuously in along term for making a knowledge network for mutual benefits.

6th Joint WS in Tokyo (Presentations and Discussions about Pavement)2. The Second Japan – Vietnam Technical Seminar
In the morning, NILIM made a presentation for the ministry of construction and theministry of transportation of Vietnam, experts of corporations, university professors, andgraduate students of university.
In the session, ITS technologies and road pavement technologies of Japan and the situation/plan of highways and the situation/ countermeasures of traffic in Vietnam were presented anddiscussed.
Especially, the graduate students of university were earnest and positive at the time ofpresentation and discussion.

The presentation session
In the evening, a round table meeting was held by the experts of soft ground measures androad pavement technologies.
In the session, soft ground measures and causes of early pavement destruction werediscussed.
As ITCT has a strong interest in abovementioned two themes and the experts fromuniversity, ministries, corporations participated, the intensive discussion was made for eachtheme.
