Training Module for Designing and Constructing with Geosynthetics
Over a period of many years LRRB investigations have identified best practices for the design and construction of low volume roads using Geosynthetics. These best practices have been summarized in the form of reports, RIS's, PowerPoint's, and a CD-ROM, most of which reside on the LRRB's web site at www.lrrb.org. In addition to these local efforts, the Federal Highway Administration (FHWA) has developed training modules incorporating best practices for the design and construction of low volume roads using Geosynthetics. The objective of this task is to develop a training module integrating the best practices resulting from LRRB research, utilizing the training module already developed by the FHWA.

Update Minnesota Seal Coat Handbook\Training Module
The LRRB handbook, Mn/DOT Publication No.1999-07, provides a solid background in seal coat materials, equipment, design and construction for the field inspector. Since publishing this handbook, research has developed new materials specifications and identified new methods for application. The objective of this task is to review these specifications and methods which then will be used to update the handbook. Useful portions of the existing handbook will be salvaged. In addition to updating the handbook, the Selected Responder will develop a 2 4 hour seal coat training module for state and local agency maintenance and construction personnel. This module will be based on information from the updated handbook. Contact: Marc Maloney, City of Shoreview Public Works Director, 651-490-4651

Review Existing LRRB/RIC Products
The Minnesota Local Road Research Board (LRRB) and their Research Implementation Committee (RIC) have developed many reports and products over a period of many years. Many of these are referenced or reside on the LRRB's website at www.lrrb.org. The objective of this task is a review of these documents and references to determine if they should be completely removed, referenced only, provided full online access (PDF) to, or updated. For those in need of updating, the purpose, tasks and costs associated with updating the individual product will be provided. Contact: John Rodeberg, City of Shoreview Public Works Director, 320-234-4208

Project Documentation Development Tool
Federal legislation requires the study and documentation of the purpose and need, the social, environmental, and economic impacts; and the location and design of federally aided projects. The objective of this task is to design a tool that would identify the issues that require study and advise the user how to document the results of the studies, assist in the determination of what type of report is required, if any, and what level of public involvement is required, if any. The proposed tool should have the same look and feel as the Project Tracking and NEEDS programs already in use by State Aid's clients, with a possible interface to capture data from the Project Tracking program. The tool would query the user for required information and provide for the printing of reports for project memos, environmental assessments, design memos, and Section 4(f) evaluations. The tool would be available for use on the State Aid for Local Transportation Division (SALT) website, with project data available for review, as needed, by local agencies, the District State Aid Engineers, SALT staff, and the FHWA.

Update Video - Weather and Loads: The Effect They Have on Roads
In 1991 the LRRB developed a video describing how pavement materials are affected by the weather and loading. This video taught the basic concepts of pavement engineering including fatigue, bearing capacity, and thermal expansion. It also identified a set of cross-sectional pavement models which were used to show how pavements respond to weather and loading. Since 1991, changes have been made relating to pavement engineering, legislation, and loading practices. The objective of this task is to update this video, incorporating recent changes relating to weather and roads and the effects they have on roads. Contact: Wayne Fingalson, Wright Co. Hwy Dept. Engineer, 763-682-7388

Ground Penetrating Radar (GPR) Capability Brochure/Demo
The objective of this task is to produce a test method document identifying the recommended procedures for using GPR resulting from LRRB INV 771. It will also include demonstrations in each district in an effort to inform local engineers on the benefits of using GPR which include potential cost savings, increased safety and time savings.

Best Practices Manual for Rehabilitation of Low Volume Concrete Roads in Minnesota
This objective of this task is to produce a manual which provides information necessary to assist local engineers and maintenance personnel in the application of the best practices of rehabilitation to the problems which exist on their low volume concrete roads. The manual is to include methods which are most applicable to Minnesota conditions. The description of the methods will include a list of deficiencies that warrant rehabilitation, the cause of the deficiencies, and the list of materials, equipment and personnel skills necessary to properly rehabilitate one or more pavement deficiencies.

Screening Tool for Using Waste Materials in Paving Projects - Demonstrations/Training
LRRB INV 795, "Screening Tool for Using Waste Materials in Paving Projects" was recently completed The software and users manual have been finalized based on suggestions received from state, county, city, and private sector personnel that participated on the technical advisory panel. In order to maintain interest and momentum for this project, training of potential users is needed. This task calls for the development of training materials and the delivery of 4 training sessions to local engineers. Contact: John Siekmeier, Mn/DOT - Materials & Road Research Lab, 651-779-5299

To Pave or Not to Pave
Two recently completed research reports have been published which attempts to provide local officials with methods to determine at what point it is desirable to upgrade a gravel road to a paved road. LRRB INV 769, report #2005-09 titled “Economics of Upgrading an Aggregate Road,” and, S.D. report #2002-10 titled “Development of Surfacing Criteria for Low Volume Roads in South Dakota.” The purpose of this task is to develop educational materials based on these reports which will be used to acquaint local engineers and officials with the factors involved with the decision process and methods used. These training materials will be delivered through CTAP to Township Officers and also through the LTAP workshop titled “Gravel Roads Maintenance and Design.” Contact Mike Sheehan, Olmsted County Engineer, 507-285-8231.

Minnesota Crash Data Analysis Tool
Minnesota Local Engineers have limited staff necessary to decode and evaluate the mounds of data available from the Department of Public Safety (DPS) and the Minnesota Department of Transportation (Mn/DOT). The purpose of this task is to develop a tool that serves as an interface between this crash data and Mn/DOT’s GIS base map. This tool will include mapping, query and reporting tools which are extensible and configurable to work with and analyze a variety of geo-referenced data. The development and delivery of 10-four hour training sessions to local agencies will also be part of this task. Contact Sue Miller, Freeborn County Engineer, 507-377-5188.
