Apply State and Provincial Rules with a Single Drop-Down in LASTRADA™ 

 

Each agency or DOT specify both rounding and significant digits in their DOT specifications. It can often be difficult to keep track of which rules apply to which sample. In LASTRADA, a single drop-down menu allows you to adjust and apply these rules with ease.

To understand the benefits of this feature, we'll look at adjusting regional settings from three perspectives.

1. Mix Design

When setting up a mix design, we establish rules by which each mix design needs to be calculated using a single drop-down setting. To apply the rules of another region, we simply copy the sample and select the new region, and the sample is automatically updated. 

2. Mixing Plant

At a mixing plant, when we want to determine whether an existing mix design fits the requirements of a new project, we make a copy of the mix design (or what we call a declaration) with it's data and apply the regional rules for the new project using the drop-down selection. Once the new settings are applied, we can re-evaluate the entire data set, its statistics and everything we may need on a report in order to determine what adjustments are needed for it to comply.

Making this adjustment at the Declaration level is a particularly powerful tool for evaluating mixes against a new specification.

3. RAP Stockpiles

With RAP stockpiles, this works the same way.  For instance, if we have a mix design for California and we need to change the design to comply with FAA, we select ASTM/AASHTO with the drop-down, and now LASTRADA will apply the appropriate rules to calculate RAP aggregate specific gravity.

This RAP functionality is particularly powerful for plants that centrally produce wrap or where wrap stockpile sits across state lines and where multiple rules have to be applied to the same stockpile.


VIDEO TRANSCRIPT:

Each agency and DOT specify both rounding and significant digits in their specs. It's difficult to keep track of
which rules apply to which samples and if you apply the wrong rules to the wrong samples you can have problems.

In this lightning demo you'll see a single drop down selection applies all proper rounding and significant digits
eliminating errors. Let's look at adjusting state specific settings from three perspectives starting with the mixed design. When I setup a mixed design I established the rules by which this mixed design needs to be calculated. In
this case this is following California rules if this mix design met gradation and other properties of let's say the Federal Highway Administration. Then all I would need to do is come down here make a copy and change this to ASTM/AASHTO and now I have a mixed design that not only meets the requirements of the Federal Highway Administration but is also calculated following those specific rules.

Now let's look at making state specific adjustments at the mixing plant using a specific mix design or what we call a declaration. Here is the same California mix design assigned to the mixing plant and ready to go with data. If you want to determine whether this mix could comply with the same federal highways project I can make a copy of this declaration with its data, change this from California to ASTM/AASHO and now I'm reading this entire data set its statistics and everything I might want to report against the ASTM/AASHTO standards. Making this adjustment at the declaration level is a particularly powerful tool for evaluating mixes against a new specification.

Now let's take a look at how regional settings are used with rap stockpiles. This particular mix design was performed in California. We know that different states have different rules. So for this example if I remove the specific gravity of the aggregate and set it to Michigan now LASTRADA is going to apply the Michigan rules to calculate an aggregate specific gravity according to Michigan. This RAP functionality is particularly powerful for plants that centrally produce RAP or where RAP stockpiles sit across state lines and where multiple rules have to be applied to the same stockpile.
