Joint Research and Partnership with Other Organizations Joint Research We conduct joint research with research organizations such as private corporations and universities to promote more efficient and effective research and development. Joint research includes an external research organization participating in PWRI-proposed research topics, i.e. “PWRI proposed project”, and projects conducted in response to a proposal from an external organization, i.e. “private proposed project”. During the 3rd period of our medium-term goals, we are scheduled to conduct approximately 100 joint projects annually in an effort to create high-quality research results.

For example, we made an Alliance/Cooperation Agreement with the Independent Administrative Agency National Institute of Advanced Industrial Science and Technology in 2007 for the purpose of mutual growth and contribution to the society through research and development. Under the agreement, a “Study on an Integrated Subsurface Structural Database” was conducted in the geological area by combining geological information with geotechnical engineering information. Additionally, information was exchanged in the areas of road and robotic technologies. In this way, both institutes work together and cooperate with each other in a wide variety of research areas. In 2010, the Center for Advanced Engineering Structural Assessment and Research (CAESAR) made an Alliance/Cooperation Agreement with the Independent Administrative Agency RIKEN on research into a small neutron imaging system to combine with elemental technology on neutron radiography, and to inspect and analyze internal structures of bridges and other structures. Application of the principle of neutron radiography, which offers excellent permeability, is expected to permit nondestructive verification of the interior condition of bridge members, which is otherwise difficult to check.

In joint research with a private sector company, PWRI has developed a new removal method that can safely and efficiently remove and collect the old coating film softened in the form of sheet without scattering coating dust in the surrounding area; it is much better than conventional mechanical methods such as blasting, disk sanding, Coating film being peeled off Site application water jetting, etc. This method received the 8th Infrastructure Technology Development Award (MLIT Minister’s Award) in 2006 and the 2nd Monodzukuri Nippon Grand Award (Prime Minister’s Award) in 2007. So far, it has been applied to a total of 115 bridges and other structures throughout Japan with a total area exceeding 180,000 m2 by the national government, local autonomy and a special public institution. Gravity thickening technology that uses ‘Water Path Forming Poles’ (Recycling Research Team) In order to efficiently treat sewage sludge, it is necessary to remove as much water as possible from the sludge and thicken it. This technique increases the sedimentation rate of sewage sludge using 'Water Path Forming Poles' (WPFPs). Specifically, by slowly rotating a sludge collector fitted with WPFPs vertically in a gravity thickener, ‘water paths’ where liquid moves easily form immediately behind the poles. This draws out the water present between sludge particles and high density thickened sludge precipitates to the bottom of the thickener. This technique received the 7th Infrastructure Technology Water path Forming poles WPFPs installed at the Engaru Wastewater Development Award (MLTL Minister’s Award) and the 1st Treatment Plant Monodzukuri Nippon Grand Award (Prime Minister’s Award) in 2005. This technique has been introduced in wastewater treatment plants in Tomakomai, Kumamoto, Imabari, etc., resulting in thicker sludge in all of these locations. Trapezoidal- CSG Dam Technology (Dam and Appurtenant Structures Research Team) To construct a dam, massive amounts of aggregate need to be provided from quarry sites. This may be a Protection concrete manner of high cost and not environment friendly . New Protection concrete CSG technologies on trapezoidal CSG (Cemented Sand and Structural concrete Gravel) dam are intended to solve these ploblems . At Inspection Gallery Seepage control concrete Rich Mix CSG the same time this technology provides the higher Auxiliary curtain grouting Foundation scupper seismic stability to the dam with a trapezoidal shape in Curtain grouting spite of utilization of low-quality aggregate provided from the construction site and mixed with cement and Taiho dam under construction (Okinawa) Trapezoidal-CGS dam water. This new technology, which can rationalize design, material and construction, protects the environment and reduces construction costs by approximately as much as 25%. We received the 11th Infrastructure Technology Development Award in 2009 on the development of this. This technology has already applied to several dam construction projects, such as the Tobetsu Dam in Hokkaido and Okukubi Dam in Okinawa. PUBLIC WORKS RESEARCH INSTITUTE 2012 47 Technique Selected as an effective and Serviceable method on the NETIS Rumble Strips (Traffic Engineering Research Team) The installation of rumble strips is a technique to prevent (Project cost per meter) vehicle-departure head-on collisions by excavating and 250,000 yen or above 250K yen Project cost recessing the centerline pavement surface. This recessed <_ 1/160 centerline generates sound and vibrations to awaken/remind the driver when a running vehicle passes over the centerline. 6K yen 5,500 yen This technique is highly effective in preventing lane-departure. 4K yen 2K yen 1,500 yen On 38 routes in Hokkaido which accounted for a total length of 0 Central Rubber Rumble 534 km and were paved with rumble strips from FY2002
