MNROAD DATA RELEASE USER GUIDE

MnROAD Database and Data Release BackgroundMnROAD, located near Albertville, Minnesota (40 miles northwest of Minneapolis-St. Paul) is one of the most sophisticated, independently operated pavement test facilities of its type in the world. MnROAD has collected data since 1993 on three unique road segments located parallel to Interstate 94:

• A 3.5-mile mainline interstate roadway carrying “live” traffic averaging 28,500 vehicles per day with 12.4 % trucks.

• A 2.5-mile closed-loop low-volume roadway carrying a controlled 5-axle tractor-semi-trailer to simulate conditions of rural roads.

• Farm loop located in the MnROAD stockpile area. MnROAD data is collected in a number of different methods and processes, which impacts how we store the data (both calculated and raw values). The purpose of this document is to describe what data has been collected, where it is stored for research use, and how to access the data.

MnROAD Data Sources Include: • Data Release 1.0 – January 2012 (described in this document) • Oracle Database (database tables and views) • Offline Data (Raw ERD, FWD history, WIM and Dynamic data to name a few) • Web Site (www.mndot.gov/mnroad) • Reports (see MnROAD web site - Reports) • Personal communication with Individual Researchers

Access to the Data MnROAD has developed this data release 1.0 that contains commonly used data spreadsheets, procedures, and tools that we have shared in the past. Right now the data can be supplied using a flash drive but we hope to improve this by placing this data on our web site and making it possible to do individual queries from our database in the future. Some bits of data (i.e. static and dynamic sensor data) can be obtained by contacting MnROAD researchers directly. If you do use MnROAD data/materials we ask you provide the following at a minimum.

• Contact Information (send us an email with the details) • Research Plan (This allows us to help find and explain the data you need) • Acknowledge MnROAD (Reference MnROAD and the data release in your final report) • Final Product (Share the final product with MnROAD) • Test Results (Share any raw lab or field testing data with MnROAD)

Version 1 – January 2012

A. MnROAD Introduction This area of the data release contains the background information you will need to better understand the MnROAD research facility and our operations. It contains information on the history, funding partners, and timeline of the MnROAD facility. The data used in this data release comes from the MnROAD database. The MnROAD Oracle database is located at the Office of Materials and Road Research in Maplewood, Minnesota. This database stores much of the data collected from MnROAD since the early 1990s but does not contain everything. Much of the data is entered into the database tables using automated data loaders, but it also may be entered by individual researchers or database staff when the data is collected at varying frequencies. From a user perspective an Oracle database is implemented as sets of objects called ‘schemas’. The name of the MnROAD schema is “MNR”. The types of objects, most used by I/T developers, are tables, views, and sequences. There are approximately 450 tables, 200 views, and 40 sequences in the MNR schema. Some data relevant to materials research is stored in other schemas – weigh in motion (WIM) data for example. Currently data is entered into a database front end called PAT (just a name) for cells, layers, material types, samples, lab and field data. The majority of the sensor data is entered from datalogger files through a daily loader. Both systems provide data checks to ensure quality and consistency in our data. More details can be obtained in other documentation.

B. Test Cell Descriptions This area of the data release contains documentation explaining the test sections or “test cells” constructed and tested at the MnROAD facility. This will give you the different designs, lanes, layer materials and thickness. This area is broken into four sections as described below.

• Cell Summary Maps - It is suggested that the user begin by viewing the Cell Summary Maps to better visualize the test cells utilized at the MnROAD facility. Since many test cells have been reconstructed at least one time, several maps have been created to show these progressions and additions over time. While the summary maps can be helpful in narrowing the search for test cells of interest, the information provided is limited to the physical layout only.

Figure 1 – MnROAD Cell Map Example

• Cross Sections by Facility Type - Users can get more detailed information about the different

test cells by looking at the files in the Cross Sections folders organized by facility (location where the cells are located). Note that information is provided in a different format within each of the folder types. This is described in more detail on the next page. MnROAD “facilities” include:

o Mainline facility consists of test cells positioned end to end which receive live interstate traffic diverted from westbound I-94 between the cities of Albertville and Monticello, Minnesota.

o Low Volume facility consists of test cells positioned end to end to create a closed-loop road. Traffic consists of a single semi-tractor trailer truck driving over the test cells approximately 80 times per day during daylight hours.

o Farm Road facility consists of test cells located in the material stockpile area of the MnROAD facility. Test cells are positioned end to end to create a portion of a loop road used primarily for periodic measurement of the pavement’s response when subjected to heavily loaded farm vehicles.

o Other facilities include those test cells located as part of driveway or sidewalks within the overall MnROAD complex.

Each facility folder contains screenshot images from MnROAD’s (online to internal MnDOT staff) database tool from PAT. These images, as shown below, contain summary information of each test cell, the location of cells in terms of survey stationing, the lanes comprising the cell, and the various layers of pavement structuring each cell. Figure 2 – Example of a Cells Layer Structure

• Design Details by Pavement Type - Test cells at MnROAD are categorized into four pavement

types: Aggregate, Composite (HMA & PCC), Asphalt (HMA), and Concrete (PCC). o Aggregate test cells are those with an aggregate type surface layer (gravel road). o Composite test cells are those with combinations of asphalt and concrete surface layers.

Examples include unbonded concrete overlays over old concrete, bonded concrete overlays over old asphalt (whitetopping), thermally insulated concrete (new asphalt over new concrete), and new asphalt overlay over old concrete [no cells yet].

o Asphalt test cells are those with a surface containing asphalt. Examples include hot or warm mix asphalt, oil gravel, porous asphalt, and novachip.

o Concrete test cells are those with a concrete surface layer. These also include pervious concrete test cells.

Each pavement type folder contains a file outlining the design parameters unique to each test cell. Information includes beginning and ending station, dates of construction and demolition, lane widths, mix specifications, layer materials, layer thicknesses, and other components depending on the particular pavement type. Unique to concrete test cells are files containing information on joint and panel identification, as well as locations of each within the test cells.

• Test Cell Maintenance History - The Lane_Events table shows the maintenance performance of

each test cell. Surface treatments, crack sealing, patching, and other maintenance treatments have been applied to particular lanes at various times within each test cell. These treatments may have an impact on field performance data and may explain sudden jumps in various performance trends.

Understanding MnROAD Station and Offset Conventions The following conventions are helpful when viewing cell details. At MnROAD, survey stationing always increases from west to east. Depending on which facility is being looked at, this often means traffic is traveling in the direction of the decreasing station. This occurs on the mainline facility test cells and those cells on the inside lane of the south low volume cells, and the outside lane of the north low volume road. Survey station and offset distances are always referred to with the following convention: Facing in the direction of increasing survey stationing, positive (+) offset distances are located to the right of the roadway centerline. Negative (-) offset distances are located to the left of the roadway centerline. The figure below provides some guidance in understanding the nomenclature.

Figure 3 – MnROAD Station and Offsets

C. Field Performance Data This directory contains files of the field data collected from the field performance measurements taken at MnROAD. The folders in this section are organized by pavement type and measurement type. For each pavement type there are folders containing Load Response data and Physical Measurements.

• Physical Measurements data consists of physical information collected during the construction

of the test cells, as well as those taken during periodic (seasonal) monitoring events. These include Soil Strength and Surface Characteristic measurements.

o Soil Strength measurements consist of results from Dynamic Cone Penetrometer (DCP), Lightweight Deflectometer (LWD), and field moisture content. Nuclear density measurements are also included both from construction and while the cell is in service.

o Surface Characteristic measurements are further divided into the categories shown below.

X Offset in feet from the centerline uses the following orientation.

Roadway Positive Negative Mainline Passing Lane Driving Lane

LVR (north side) Inside Lane Outside Lane LVR (south side) Outside Lane Inside Lane

Farm Loop Eastbound Lane Westbound Lane Y Distance in feet down the road. STA is a “Y” distance and increases as distances move to the

east both on the mainline, LVR, and farm loop. Z Distance is typically a measurement or difference in elevation. When using the ALPS negative is

defined as below the beam.

The sensor details for each test section basically lay out the station, offset, and depth for each individual sensor. Please note that in some cases new sensors have been installed into older underlying layers. Thus it may appear that a newer test cell number will be associated with a sensor located in an older underlying layer with a different cell number. Note: Due to the extremely large volume of data collected from the MnROAD sensors has not been included in this version of the data release, but will be added in future versions as data qualification has been accomplished

E. Material Sampling & Testing This directory contains files describing the material samples taken from the MnROAD facility, as well as the results of tests conducted on the samples at MnDOT Materials Research and Engineering Laboratory and by several of our external research partners. The folders in this section are organized by material type (Aggregate & Soil, Asphalt, and Concrete). The laboratory tests include both standard QC/QA tests and specialized research tests. Documentation is also provided to describe the sampling and testing process in greater detail.

F. Weather Station Data This directory contains files summarizing the data gathered from two onsite weather stations at the MnROAD facility. The averages of the combined weather data from the two stations is provided for each year through 2011 at 15 minute intervals. The types of weather data include air temperature, precipitation, wind speed and direction, humidity, and solar radiation.

G. Traffic Loading Data Traffic data is included in the data release under the traffic loading directory. It contains the data and the documentation of traffic loads applied to the MnROAD test cells. The type and volume of traffic loading is different between the two main MnROAD facilities and is documented completely and outlined below.

• Mainline Traffic - Traffic loading on the “Mainline” facility test cells consists of live interstate traffic diverted off of westbound I-94 between the cities of Albertville and Monticello, Minnesota. Traffic loadings are interrupted periodically (traffic is diverted back to the parallel lanes of the old westbound I-94) so that physical measurements can be safely performed by MnROAD personnel. Traffic is also removed during major test cell reconstruction events. MnROAD averages 750,000 Flexible and 1,000,000 Rigid ESALS (not taking into account the traffic switches) a year for the 28,500 ADT and 13% Trucks that travel over MnROAD mainline. The following files are included in the data release, in which the data has been processed up to December 31, 2011:

o ML_Traffic Switches.csv This files documents the dates and times lane closures were done on the mainline.

o Mainline Traffic Summary (Dec 2011).xlsm This file is outlined in the documentation of the mainline traffic. It includes an ESAL calculator that the user can input the date ranges for a particular cell of interest. This calculator takes into account the lane closures for the traffic switches.

o Mainline_Traffic_Summary.pdf This file describes how the data is processed from raw weigh in motion data all the way through to ESALs for each day and lane.

• Low Volume Road - Traffic loading on the Low Volume road consists of a single semi-tractor trailer “MnROAD” truck that passes over test cells an average of 80 times each day during daylight hours. The traffic loadings have stayed consistent over the years with the following parameters.

o 1994 to 2007 During this period MnROAD was studying the effects of overloaded trucks on our low volume roads. To accomplish this study the MnROAD truck traveled over the inside lane loaded at the Minnesota legal gross vehicle weight limit of 80,000 pounds. This loading configuration was used an average of 4 days per week. During the same time period, the MnROAD truck traveled over the outside lane with a total gross vehicle weight of 102,000 pounds. This loading configuration was used on average 1 day per week. This loading scheme produced approximately equal ESALs on the two lanes.

o 2007 to Today MnROAD is now studying the effects of the environment (no traffic) vs. legal loading. The MnROAD truck now travels over the Low Volume inside lane only, loaded with a gross vehicle weight of 80,000 pounds. On average, 80 laps are completed each day, 5 days a week, during daylight hours.

The traffic data files in this data release include the following: o LVR Traffic Summary (Dec 2011).xlsx

This file contains daily and cumulative traffic characterization in the form of laps and 18k Equivalent Single Axle Loads (ESALs) by pavement type.

o Low Volume Road Traffic Descripton.pdf This file contains information on the MnROAD truck dimensions and axle weight measurements.

H. Database Table Descriptions This directory contains two spreadsheets that describe both the data release and database tables and columns. These include:

• Data Release - A glossary file describing the column definitions for all the information presented in this data release. It can be used for reference when using the data, particularly to check column heading abbreviations and measurement units.

• Database Tables and Columns – These are the actual database tables in the MnROAD database queried to create the data release files. The SQL is included in the data release and the files in the release typically come from more than one table. This is why the data release files do not typically have the same names as the database tables.

A listing of all tables and views in the MnROAD database schema MNR and WIM are included in Appendix B of the Data Release User Guide. If you are interested in any of the other tables in the database please contact us for help.

I. Reports This directory contains a file that lists the research reports, conference papers, and technical briefs that have been written about MnROAD research projects. The file can be searched to find a particular author, title, or keyword. The user is encouraged to visit the MnROAD website to view the most current listing of research reports (http://www.dot.state.mn.us/mnroad/reports/index.html).
