GyroPave™ for Windows XP 1–1

INTRODUCTION GyroPave for Windows XP is the software companion to Troxler’s Model 4140 and 4141 Gyratory Compactors. GyroPave provides a set of flexible and powerful tools to collect and process densification data from the gyratory compactor. GyroPave can calculate the Federal Highway Administration (FHWA) Superpave™ (Superior Performing Asphalt Pavements) mix design properties. GyroPave provides a number of sample worksheets (templates) and macros for Microsoft Excel®, as well as Visual Basic® procedures that the user can use to automate a number of common tasks in the Superpave mix design process. GyroPave simplifies the design process by: ♦ Collecting data from the gyratory compactor during or after

compaction

♦ Automatically performing the mix design calculations The user can view, print, or graph the resulting densification properties. GyroPave enables the user to manage multiple project files. Project files contain compaction data loaded either directly from the compactor or from stored compactor data files within the computer. These project files can contain up to twelve samples with varying mix design parameters. GyroPave is not limited to designing Superpave mixes. GyroPave also enables the user to perform field performance testing with the compactor to ensure compliance with Superpave. In addition to the analysis provided with this program, the user can copy the height data from the compactor to another spreadsheet.

INTRODUCTION Data may be entered manually into the GyroPave for Windows XP spreadsheets, or may be collected from the gyratory compactor using the GyroTalk application included in the GyroPave software. There are two methods of collecting data from the gyratory compactor. The first method is to load data in real time, where the user opens the GyroTalk application and starts the compactor. Data is then loaded into GyroTalk during the compaction cycle. The second method is to load data into GyroTalk from stored compactor tests performed earlier. Figure 3–1 shows the GyroTalk window. After data has been downloaded to GyroTalk, the height versus gyrations is plotted on the graph in the left portion of the display. The gyration number and height are also listed sequentially in the table in the right portion of the display.

AGGREGATE BLEND WORKSHEETS The Aggregate Blend worksheet (Figure 4–4) and Aggregate Blend Curve chart (Figure 4–5) are used to design up to four potential aggregate structures to be used in the mix design. Click on the tab (9.5-mm, 12.5-mm, 19.0-mm, 25.0-mm, or 37.5-mm as entered into the Specs worksheet) for the Aggregate Blend worksheet. Figure 4–4 shows the Aggregate Blend worksheet for a 9.5-mm nominal maximum size aggregate. Note that the Aggregate Blend worksheet is large and cannot be viewed completely on a single screen. The worksheet contains four aggregate blend sheets for designing up to four potential aggregate structures. For each aggregate structure, enter the aggregate stockpile and the stockpile gradations into the appropriate cells. Then enter the gravimetric and absorption properties of each stockpile. Finally, enter the target aggregate mass to be used in each sample.

Figure 4–4. Aggregate Blend (9.5-mm) Worksheet

Figure 4–5. Aggregate Blend Curve (9.5-mm) Chart Data must be entered into the light blue cells on the worksheet (Figure 4–4). In addition, the stockpile percentages, which are arranged in alternating rows of green and gray, must also be entered by the user. The worksheet allows for blending of up to six stockpiles, but the GyroPave software will accept data for less than six. To determine the target aggregate blend, enter the percentage of each stockpile to be used in the aggregate blend. The Aggregate Blend worksheet provides a number of checks to ensure that the blend complies with Superpave criteria. If the combined percentage of the stockpiles does not equal 100%, the worksheet displays INVALID next to the Combined Gradation cell.

Similarly, if the combined gradation violates the criteria for one or more control points, the worksheet displays INVALID next to each control point violation. Finally, if the combined gradation violates the restricted zone, the software displays a WARNING message.


The compliance of an aggregate blend with the Superpave control points and restricted zone criteria can also be viewed using the Aggregate Blend Curve chart (Figure 4–5). For each aggregate blend, the chart shows the percent passing versus the sieve size raised to the 0.45 power. The user can determine graphically whether or not the aggregate blend is within the control points and outside of the restricted zone. The last column of the Aggregate Blend worksheet gives the mass of aggregate retained on each sieve necessary to meet the desired gradation. As a check, the last cell in the Retained On Sieve Mass column totals the mass for all sieve sizes. This value should equal the aggregate mass entered by the user in the blue Aggregate (grams) cell on the third-to-last row of the worksheet. To prepare batches by drawing from a range of sieve sizes, the user must manually add the values in the Retained On Sieve Mass column to determine the range mass required to meet the target gradation of the aggregate blend. If an INVALID message appears for an aggregate blend, the mass from the particular sieve size in question will also display INVALID rather than the mass value. The total aggregate mass will also be displayed as INVALID rather than the total aggregate mass value. If the blend violates the restricted zone, the WARNING indication is displayed next to the mass value. However, the indication does not replace the mass value (as is done by an INVALID message). The bottom section of each blend displays the following values: Gse – Effective specific gravity of the aggregate blend (calculated) Vba – Volume of absorbed binder (calculated) Vbe – Volume of effective binder (calculated) Ws – Mass of aggregate (calculated) Pbi – Initial trial asphalt content by weight of mix (calculated) AC (wt of agg) – Asphalt content as a percentage of the weight of

aggregate (calculated) Aggregate (grams) – Sample mass of aggregate (entered by user) AC – Mass of asphalt required to meet Pbi

4–8

The Total Mass of Mix cell is determined from the data entered into the Aggregate Blend worksheet. After the four aggregate blends are determined, the Aggregate Blend Curve chart shows the 0.45 Power gradation curve for each blend. Any change to an aggregate blend is reflected automatically on the gradation curve. Data from the Aggregate Blend worksheet can be transferred to the Property worksheet by clicking on the Transfer Data to Property Sheet button on the Aggregate Blend worksheet.

NOTE No data can be transferred to the Property worksheet until after gyratory compaction (height-versus-gyration) results have been downloaded or manually entered into the Property worksheet. The following section provides information on downloading compaction data from GyroTalk into the Property worksheet. Since this information is used in the volumetric analysis of compacted mix specimens, it is not necessary to transfer the data from the aggregate blend sheets until after the compaction results have been acquired.

NOTE

If preferred, all Property worksheet data may be entered manually.

BULK WORKSHEET The Bulk worksheet (Figure 4–7) is used to calculate the bulk specific gravity values for the compacted specimens and to transfer the pertinent data to the Property worksheet. To use the Bulk worksheet, enter A, B, C, and °C values for each sample (Sample 1a, Sample 1b, Sample 1c, and so on), where:

A = Mass in grams of sample in air

B = Mass in grams of saturated surface-dry sample

C = Mass in grams of sample in water

°C = Water temperature in degrees Celsius After entering these values for all samples, click on the Calculate button. GyroPave calculates the final Gmb (Nmax) value for the sample (1a, 1b, 1c, and so on).

4–12

Figure 4–7. Bulk Worksheet, DAS Phase The worksheet also computes the average Gmb for the three-sample grouping (Sample 1, Sample 2, and so on). The final Gmb is calculated from the following formula:

Gmb = (A / (B – C)) × K where K is the K factor. The K factor is determined from the Temp °C /K Factor table, based on the temperature of the water bath used to determine the specimen bulk specific gravity. The default temperature is 25 °C. GyroPave calculates the bulk specific gravity of each sample (1a, 1b, 1c, and so on) at Nmax. The software also calculates the corrected bulk specific gravity values at Nini and Ndes, and the average corrected bulk specific gravity values for each three-sample grouping (Sample 1, Sample 2, and so on). GyroPave also transfers the Gmb (Nmax) value and the dry mass (weight) of each compacted specimen to the Property worksheet.

Data must be entered into the light blue cells on the worksheet (Figure 4–11). In addition, the stockpile percentages, which are arranged in alternating rows of green and gray, must also be entered by the user. The worksheet allows for blending of up to six stockpiles, but the GyroPave software will accept data for less than six. To determine the target aggregate blend, enter the percentage of each stockpile to be used in the aggregate blend. The design aggregate structure determined in the first phase of the mix design should be entered as the aggregate blend used in this phase. The OAC NMS Mix worksheet provides a number of checks to ensure that the blend complies with Superpave criteria. As shown in Figure 4–11, if the combined gradation percentage of the stockpiles does not equal 100%, the worksheet displays INVALID next to the Combined Gradation cell. Similarly, if the combined gradation violates the criteria for one or more control points, the worksheet displays INVALID next to each control point violation. Finally, if the combined gradation violates the restricted zone, the software displays a WARNING message. The compliance of an aggregate blend with the Superpave control points and restricted zone criteria can also be viewed using the OAC NMS Mix Curve chart (Figure 4–12). The chart shows the percent passing versus the sieve size raised to the 0.45 power for the aggregate blend used. The user can determine graphically whether or not the aggregate blend is within the control points and outside of the restricted zone.

The last column of the OAC NMS Mix worksheet gives the mass of aggregate retained on each sieve necessary to meet the required gradation for preparing batches. As a check, the last cell in the Retained On Sieve Mass column totals the mass for all sieve sizes. This value should equal the aggregate mass entered by the user in the blue Aggregate (grams) cell on the third-to-last row of the worksheet.


To prepare batches by drawing from a range of sieve sizes, the user must manually add the values in the Retained On Sieve Mass column to determine the range mass required to meet the target gradation of the aggregate blend. If an INVALID message appears for an aggregate blend, the mass from the particular sieve size in question will also display INVALID rather than the mass value. The total aggregate mass will also be displayed as INVALID rather than the total aggregate mass value. If the blend violates the restricted zone, the WARNING indication is displayed next to the mass value. However, the indication does not replace the mass value (as is done by an INVALID message). In the OAC NMS Mix worksheet, the aggregate mass and trial asphalt contents are entered into the blue cells of the upper table. The third row of the table provides the mass of asphalt liquid required to achieve the desired asphalt content. The last row of the table gives the total mass of mix in each sample based on data entered by the user.

Figure 5–7. Bulk Worksheet, DAS Phase The worksheet also computes the average Gmb for the three-sample grouping (Sample 1, Sample 2, and so on). The final Gmb is calculated from the following formula:

Gmb = (A / (B – C)) × K where K is the K factor. The K factor is determined from the Temp °C /K Factor table, based on the temperature of the water bath used to determine the specimen bulk specific gravity. The default temperature is 25 °C. GyroPave calculates the bulk specific gravity of each sample (1a, 1b, 1c, and so on) at Ndes. The software also calculates the corrected bulk specific gravity values at Nini, and the average corrected bulk specific gravity values for each three-sample grouping (Sample 1, Sample 2, and so on). GyroPave also transfers the Gmb (Ndes) value and the dry mass (weight) of each compacted specimen to the Property worksheet.


RESULTS DATASHEET The Results datasheet (Figure 5–8) displays the average results of the specimen compactions for each trial aggregate blend. All values on the Results datasheet are calculated by the GyroPave software; no value is entered by the user. The second table contains results of calculations used to suggest either initial trial asphalt contents for optimum asphalt content determination, or trial asphalt contents for further testing of trial aggregate blends in the selection of design aggregate structure.

Click on the tab (OAC 9.5-mm, OAC 12.5-mm, OAC 19.0-mm, OAC 25.0-mm, or OAC 37.5-mm as entered into the Specs worksheet) for the OAC NMS Mix worksheet. Figure 5–11 shows the worksheet for a 37.5-mm nominal maximum size aggregate. The OAC NMS Mix worksheet contains one aggregate blend sheet for the design aggregate structure to be used in the mix design and a table for the calculation of up to four asphalt contents. Using the design aggregate structure determined in the first phase of the Superpave mix design process, enter the aggregate stockpile and stockpile gradations, and the percentages of each stockpile used. Enter the target aggregate mass to be used in each sample and the asphalt contents to be tested.

The worksheet allows for blending of up to six stockpiles, but the GyroPave software will accept data for less than six. To determine the target aggregate blend, enter the percentage of each stockpile to be used in the aggregate blend. The design aggregate structure determined in the first phase of the mix design should be entered as the aggregate blend used in this phase. The OAC NMS Mix worksheet provides a number of checks to ensure that the blend complies with Superpave criteria. If the combined gradation percentage of the stockpiles does not equal 100%, the worksheet displays INVALID next to the Combined Gradation cell. Similarly, if the combined gradation violates the criteria for one or more control points, the worksheet displays INVALID next to each control point violation. Finally, if the combined gradation violates the restricted zone, the software displays a WARNING message as shown in Figure 5–11. The compliance of an aggregate blend with the Superpave control points and restricted zone criteria can also be viewed using the OAC NMS Mix Curve chart (Figure 5–12). The chart shows the percent passing versus the sieve size raised to the 0.45 power for the aggregate blend used. The user can determine graphically whether or not the aggregate blend is within the control points and outside of the restricted zone. The last column of the OAC NMS Mix worksheet gives the mass of aggregate retained on each sieve necessary to meet the required gradation for preparing batches. As a check, the last cell in the Retained On Sieve Mass column totals the mass for all sieve sizes. This value should equal the aggregate mass entered by the user in the blue Aggregate (grams) cell on the third-to-last row of the worksheet.


To prepare batches by drawing from a range of sieve sizes, the user must manually add the values in the Retained On Sieve Mass column to determine the range mass required to meet the target gradation of the aggregate blend. If an INVALID message appears for an aggregate blend, the mass from the particular sieve size in question will also display INVALID rather than the mass value. The total aggregate mass will also be displayed as INVALID rather than the total aggregate mass value. If the blend violates the restricted zone, the WARNING indication is displayed next to the mass value. However, the indication does not replace the mass value (as is done by an INVALID message). In the OAC NMS Mix worksheet, the aggregate mass and trial asphalt contents are entered into the blue cells of the upper table. The third row of the table provides the mass of asphalt liquid required to achieve the desired asphalt content. The last row of the table gives the total mass of mix in each sample based on data entered by the user.
