Book Synopsis Mn/DOT Intelligent Compaction Implementation Plan by : D. Lee Petersen
Download or read book Mn/DOT Intelligent Compaction Implementation Plan written by D. Lee Petersen and published by . This book was released on 2009 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: The objective of this project was to provide a qualitative assessment of the Minnesota Department of Transportation's Intelligent Compaction (IC) Specifications. IC is an attractive approach to evaluate the compaction quality because it involves continuous and instantaneous evaluation of the soil through machine-drive power or drum vibration monitoring. Four construction sites utilizing IC were visited: (1) TH 36 in North St. Paul, involving both granular and nongranular soils; (2) US 10 in Staples, with granular soil; (3) TH 60 in Bigelow, with nongranular soil; (4) US 10 in Detroit Lakes, involving both granular and nongranular soils. The report integrates comments from the four site visits and provides an interpretation on the use of IC at each site. As the technology now exists on the equipment used at these locations, IC provides only an index, which is specific to the conditions associated with a particular site. An interpretation of comments provided the basis for the following recommendations: Use light weight deflectometers (LWD) for quality assurance of stiffness; Establish a procedure to determine the target LWD value; Eliminate calibration areas (control strips); Simplify IC data evaluation and presentation; Calibrate the IC roller and related transducers; Support development of alternative IC methodologies; Simplify or eliminate moisture corrections.
Book Synopsis Intelligent Compaction and In-situ Testing at Mn/DOT by : D. Lee Petersen
Download or read book Intelligent Compaction and In-situ Testing at Mn/DOT written by D. Lee Petersen and published by . This book was released on 2006 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes an intelligent compaction demonstration project on Mn/DOT TH 53 in Duluth, MN, and the associated field and laboratory testing. The project was conducted during September 2005, using a Caterpillar Model CS-563E vibratory soil compactor, equipped with Intelligent Compaction (both Compaction Meter Value (CMV) and energy or power) and global positioning system (GPS) technology. A Prima light-weight deflectometer (LWD), dynamic cone penetrometer (DCP) and Humboldt GeoGauge were used to collect in situ companion test data at 42 locations. Mn/DOT conducted gradation, moisture content and Procter tests. Location and Compaction Meter Value (CMV) were downloaded for comparison with the in situ testing. CMV data was compared to the in situ data on a point-by-point basis and on the basis of the overall distribution. In general, poor correlations were obtained on a point-by-point basis, likely due to the depth and stress dependency of soil modulus, and the heterogeneity of the soils. Good correlations were obtained between CMV values and DCP measurements for depths between 8-inches and 16-inches deep. The Caterpillar Compaction Viewer software, although still in development at the time of testing, is functional and is well integrated with GPS. It is easy to extract data and do more sophisticated analyses. Surface-covering documentation adds value by identifying potential problem areas where compaction is limited by material, moisture or subgrade deficiencies. LWD testing protocol must be followed to obtain useful results, since measurements vary significantly between successive tests. Relatively good correlations were obtained between LWD and GeoGauge. The GPS technology used for the demonstration is not adequate to distinguish between lifts.
Book Synopsis Implementation of Intelligent Compaction Performance Based Specifications in Minnesota by : David J. White (Ph. D.)
Download or read book Implementation of Intelligent Compaction Performance Based Specifications in Minnesota written by David J. White (Ph. D.) and published by . This book was released on 2009 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study documents relationships between intelligent compaction measurement values (IC-MVs) and various insitu point measurement techniques for monitoring compaction of non-granular and granular materials. Factors affecting correlations are discussed (e.g., soil type, moisture contents, stress level, etc.). Measurements from earth pressure cells document the relationship between in-ground stresses for rollers and various in-situ test methods. Comparisons were made between test roller rut depth measurements and IC-MVs and various point measurements as a quality assurance (QA) check for the subgrade pavement foundation layer. It was concluded that IC-MVs and in-situ point measurements can serve as reliable alternatives to test rolling. Site specific target values were calculated for IC-MVs, dynamic cone penetrometer (DCP), light weight deflectometer, (LWD), and shear strength. Measurement error and protocols for field testing were evaluated for LWDs. Laboratory compacted samples were used to assess an approach for determining LWD field target values. Future research is recommended to evaluate this approach for materials on a state-wide basis. Results from field studies were used to develop four IC specification options. Three specifications do not require on-site roller calibration. One specification option requires on-site calibration of IC-MVs and in-situ point measurements. This specification option has the advantages of quantifying risk, establishing a framework for a performance specification, providing information for incentive-based pay, and better linking as-built quality to long-term performance. An IC training/certification program, new IC field data analysis tools, and additional pilot projects will assist with greater implementation of these technologies.

Available in PDF, EPUB and Kindle. Book excerpt: The main purpose of this research is to determine the possibility of substituting in-place core density (% Gmm) for Hot Mix Asphalt (HMA) Quality Assurance (QA) in Indiana Department of Transportation Specification with Intelligent Compaction (IC) measurements. A questionnaire survey and interviews were conducted to gather information on: 1) the usage of IC technology in other states, 2) the benefits of applying IC technology, and 3) the application of IC technology for Quality Control/ Quality Assurance (QC/QA). Also the data available from IC demonstration performed on US 52 in 2009 was analyzed to identify the relationship between in-place density values (i.e., Non-Nuclear Gauge, NNG) and the IC Measurement Values (ICMVs).According to survey responses from 26 agencies, there was no state DOT using IC for QA as of June 2014. Only two DOTs, including Alaska and Vermont have adopted IC in HMA compaction for QC. The reasons for not using IC technology in current QC/QA practices were: 1) satisfaction with existing QC/QA procedure, 2) difficulty of adjustment due to the lack of specifications in determining stiffness in HMA, and 3) lack of availability of IC equipment with contractors. However, it was responded that the most benefits of IC was night time paving and uniform compaction in QC.Analysis of the ICMV data obtained from a demonstration project on US 52 indicated that a NNG correlation showed an R2 value of 0.67. This finding supports the IC implementation in the current INDOT HMA QC. It should be noted that a correlation between core-density and ICMV could not be determined due to lack of reliable data.In conclusion, the research could not identify any possibility of adding IC into the INDOT specification for QA based on the survey, phone interviews and analysis of the data obtained from IC demonstration on US 52.
