Minnesota's Quality Management Program began in 1986 when the Minnesota Department of Transportation (Mn/DOT) and the Minnesota Asphalt Pavement Association (MAPA) formed a partnership to develop a process for improving the quality of asphalt pavements within the state. A Quality Management Task Force was formed with members representing Mn/DOT Construction and Materials, Counties, Cities, Consultants, FHWA, Hot Mix Asphalt (HMA) Contractors and a Consultant hired as a technical advisor. The Task Force was charged with the goal to "Develop and Implement a Quality Management Program to Assure Construction of Quality Asphalt Pavements". This was the beginning of a continuous evolution which has and will continue to guide the production and placement of HMA Mixtures.

Mn/DOT research has indicated that intelligent compaction (IC) will improve construction quality and efficiencies for the Contractors and Mn/DOT field staff. Experience thus far has illustrated that quality control, quality assurance and research activities were problematic using the software provided by the roller manufacturers. The manufacturers’ software is proprietary, expensive, subject to change, and generally did not provide the functionality required by Mn/DOT. Hence, the Department chose to develop software and processes fitting their specific needs. The work included: 1. Development of database structures for managing and archiving IC data 2. Software to import and validate IC data, populate the database and write geographic information system (GIS) shapefiles 3. Processes and tools to manage, display and evaluate IC data within ArcInfo GIS software. The end product of this research is equally suited to compaction of both unbound and bound materials used to construct the entire flexible pavement structure. This final report describes the target functionality, terminology, geodatabase structure, import and filtering software and ArcInfo geographic information system (GIS) platform processes.

| Release | : 1976 |
| Genre | : Electronic traffic controls |
| ISBN | : |
This handbook, which was developed in recognition of the need for the compilation and dissemination of information on advanced traffic control systems, presents the basic principles for the planning, design, and implementation of such systems for urban streets and freeways. The presentation concept and organization of this handbook is developed from the viewpoint of systems engineering. Traffic control studies are described, and traffic control and surveillance concepts are reviewed. Hardware components are outlined, and computer concepts, and communication concepts are stated. Local and central controllers are described, as well as display, television and driver information systems. Available systems technology and candidate system definition, evaluation and implementation are also covered. The management of traffic control systems is discussed.
Ultra-thin Bonded Wearing Course Performance Update, Minnesota

Ultra-thin bonded wearing course (UTBWC) is a method of extending pavement life for both hot mix asphalt (HMA) and Portland cement concrete (PCC) roads. For this reason the Minnesota Department of Transportation (Mn/DOT) proposed and constructed test sections in the summer of 2004 and 2005 in the Twin Cities to demonstrate the effectiveness of this type of design. The focus of this report is about how a construction of UTWBC would improve ride quality of a pavement and if any distresses occurred after the construction. By obtaining data from Mn/DOT Pavement Management Office, UTBWC showed promise for future pavement maintenance design. After the construction of UTBWC, ride quality index (RQI) improved without any major distresses. Some of the minor distresses observed after construction were longitudinal and transverse joint distresses that were a reflective cracking from the bottom of the in-place concrete joints.
