PART IV: Summary of Comments17-May-10Reviewer Comments Distribution of Ratings■ It's time to stop planning to plan and creating documents that end up sitting on the shelf, and starting acting to resolve theproblem. $200K would be better spent elsewhere.Item #85:E-07Quantifying Long-Term Performance of Draped andFlexible Fence Rockfall Protection Systems(17)(46)NR 0 1 2 3 4 5SCOR 1 2 5 6 3RAC 2 7 7 11 10 6 6Standing Committee on Research■ Potentially significant safety issues involved.■ Recommend this as a Synthesis. Considerable savings could be realized by reducing duplication of already establisheddesigns and construction methodologies.■ Recommend consider a pooled fund for the states affected.■ F-07 would be a preferred study but it does not address maintenance and durability issues. These two can be combinedfor a more comprehensive project.■ The objective appears to be no more than collecting and summarizing existing information through inspections, surveys,a literature search and soliciting manufacturer information. It is doubtful that any maintenance data about wire meshtreatment would be applicable from site to site since each site tends to be unique. Potential Synthesis topic.■ [Rating: 4]Research Advisory Committee■ This project should be combined with 2011-F-07.■ This is a critical need. The consequences of failure in terms of safety and mobility. Should be combined with Problem F-07.■ Combine with F-07■ This Department does not have a need for the majority of these products. The condition/performance of these productswould seem to be easily discerned by visual inspection or experience of those installed. It would seem that the true longtermperformance should be something established by the manufacturers of these products.■ MSDOT does not have this issue in our stateOther■ [Rating: 3]Item #86:C-12MEPDG Inputs for Warm Mix Asphalts(17)(46)NR 0 1 2 3 4 5SCOR 2 3 5 3 2 2RAC 1 7 7 8 8 9 9Standing Committee on Research■ While I think the work is needed, I see several obstacles. In part, some of the characterization and comparison inproperties has/will occur during 09-43 and 09-47A. While the information is absolutely needed, I don't know that anational study will be able to capture the variations that individual states will demand be accounted for - work forproviding HMA inputs has generally been occuring on a regional or state project basis due to the differences in mixtureproperties related to source materials, state specifications, etc. This project would be excellent for focusing ondetermining if the models used for HMA are applicable for WMA, but to provide mixture- and technology-specific inputsmay be overly ambitious and not succeed in meeting the expectations of the users.IV-62
