Completing an asphalt mix design includes a lot of moving parts. There is data for trial blends, data for trial points, data for verification tests, and all these results are typically managed in multiple disjointed Excel files. In LASTRADA, technicians and engineers can enter and access the information they need to complete a mix design in a single organized module in LASTRADA.
Using the Asphalt Mix Design Module
On the left side of the LASTRADA Mix Design Module, you'll find three tabs: the Header tab, the Aggregate Blend tab, and the Trial Mixes tab.
The Header tab is where the basic mix design data is entered. This includes information such as the mix design ID, the assigned specification, the design method, and the DOT rules to follow when developing the design.
The Aggregate Blend tab includes the various blend trials for the mix design. On this tab, you can view the calculated and measured properties for the blend, you can edit properties of the aggregates being used, and you can access a specialized blending tool to assist in developing the blends.
The Trial Mixes tab is where trial point data is entered and analyzed. This is where you mix up points at different asphalt contents for each of the blends. Here, you can calculate or measure different properties, and once you determine the optimum asphalt content, you can create verification points in the Trial Mix subsection.
From within the Trial Mixes tab, technicians can create batching sheets for batching asphalt mix points, and engineers can generate reports from existing DOT or custom formats.. Both actions are initiated by selecting the document icon .
Since all of the data is accessible from within this module, the data can be exported with a single click. To determine which mix design blend is the best one to use, simply export the data from LASTRADA by clicking the XML export button , and then import the data into your pre-designed spreadsheet for analysis.
