How to Keep Ignition Calibrations Organized & Ready to Use in LASTRADA™


With each mix design and RAP stockpile having its own unique calibration, and some calibrations being specific to an individual ignition oven, keeping your ignitions calibrations organized is challenging. During and prior to production, some specifications require that you understand the influence of the ignition oven on gradation and binder content, so having a system to keep track of all the different calibrations is crucial. In this Lightning Demo, we'll show you how LASTRADA™'s declaration structure applies and manages oven correction factors for asphalt mixes and RAP stockpiles.

RAP Declaration Module

To calculate an offset for gradation and binder content, use the correlation correction factors button to pull in extraction and associated ignition tests. Use the actual correlation button to change the sign to match local standards. 

Software Asphalt Declaration Module


Asphalt Declaration Module

Define an ignition oven correction factor for every mix at every plant, either one correction per mix design or unique corrections for each plant. 

Asphalt QC Module

LASTRADA takes the asphalt content by ignition and aggregate gradation from a recovered sample and applies the appropriate correction factor.

LASTRADA's declaration structure makes it easy to keep track of your ignition calibrations. LASTRADA has various modules to organize your mix designs, RAP stockpiles, and ignition oven calibrations.

The ignition oven is a great tool for recovering aggregates from hot mix asphalt. To perform a gradation some
specifications require you to understand the precise influence of the ignition oven on gradation prior to and during production.

In this Lightning Demo, I'll show you how LASTRADA applies and manages ignition oven correction factors to both asphalt mixes and rap stockpiles. Here we are in LASTRADA wrapped declaration and we have a button here called correlation correction factors. Where we can pull an extraction and associated ignition tests in the software will calculate an offset for both gradation and binder content for us. We even have a button here to change the
sign when we're making a report so it matches our local standards.

On the asphalt mix side, we have the ability to find an ignition of and correction factor for every mix at every plant.
Therefore, we can have one correction factor for every mix design or we can have unique ones at each plant where we may have individual ignition ovens. Now, when I'm in the Asphalt QC module and my sample has both an asphalt content by ignition and an aggregate gradation from a recovered sample LASTRADA is going
to take this actual non-corrected gradation and it's going to apply the appropriate correction factor that we
assigned to this particular product at this plant.
