The JMF Verification Tool is a web-based application developed by the California Department of Transportation, Materials Engineering & Testing Services (METS) for contractors to electronically submit JMF proposals and design data and for the ability to verify JMF submittals for Caltrans District Labs.
The JMF Verification Tool provides a centralized database for automating JMF verification of test results. Being web based allows Contractors and Caltrans to have access to statewide JMF data. By expanding DIME to include the tests required for JMF verification we can provide statewide consistency in test records and allow stakeholders an efficient means to view real-time test data.
The JMF Tool is designed to accommodate HMA mix designs for Type A HMA, RHMA-G, OGFC BWC-G, Type AHMA for Bridge Decks and Type A HMA Minor. Sample and test result data submitted through this tool are stored in DIME (Data Interchange for Materials Engineering) and are available for sharing and analysis there.
Login to the Job Mix Formula (JMF) tool using your Data Interchange for Materials Engineering (DIME) login username and password. If you do not have a DIME account you must first create one by visiting the DIME login page and following the instructions found on that page to have an account created for you.
After logging in to the JMF tool, you can view the labs you are associated with by clicking on your name in the top-right side of the navigation section. To switch to a different organization, simply click on the name of the organization in the list. You can confirm which organization account you are accessing by looking at the message toward the top of the main content section.
The JMF Dashboard is your landing page that lets you see the most current data related to your HMA Mix Designs and JMF Submittals. There are 4 major sections of the dashboard:
From the JMF Dashboard page, click on the "Start new HMA Design" button at the top of the HMA Mix Design section.
To start a new HMA Mix design, select the HMA Producer Information, the HMA Qualified Laboratory Information, the Hot Mix Asphalt (HMA) Information and optionally provide notes for this HMA mix design. If the HMA Producer or the HMA Qualified Lab is not listed — or any information is incorrect — please contact the Caltrans Materials Administrator.
After clicking the "Next" button, you will be brought to a page that allows you to input sample and test result data for your proposed HMA mix design.
Each section is listed along the left side. You may navigate from one section to the next or jump around. The entered data is automatically saved for your convenience and lets you pick up where you left off if you have to step away from the data input process.
Each section related to mix design component materials will contain a button that allows you to create a new sample. Simply click on the "Create.." button and enter basic information about the sampled material in the pop-up box.
Once a sample is created, you will have the option to enter results for QC tests performed on the sample. Each input page is different depending on the material type, but each test designated for the material will have at least one button labeled "Enter Data" on the page. Clicking on the button will display a pop-up box. Simply fill in the QC test results and click the "Save" button. The pop-up will close, and the appropriate data will be populated automatically on the form. Continue until you have all test results entered for all material types.
After all data for your HMA Mix Design is ready, you may submit a proposal to Caltrans to use that HMA mix on a Caltrans project.
To start a new JMF Submittal, either click the "New Submittal" link next to the HMA Mix Design on the dashboard or click the "New Submittal" at the top of the HMA Mix Design input page.
First, review some basic information related to the JMF and click "Create JMF Submittal" to begin the submittal process.
You will be brought to a page that allows you to specify information required in the JMF submittal process. The navigation down the left side of the page will guide you through the process. Click on a tab to view a section and enter the required information in each section.
Once all required information is entered, click on the "Submit" tab to provide final information to send your proposal to Caltrans for verification. Choose which project personnel to send the submittal to. You may add recipients to the list as necessary. Sign the submittal with your mouse (or finger on mobile devices) and click the "Submit to Caltrans". You will see a confirmation message once the JMF submittal is received in the system.
All sample and test result data entered in the JMF tool will be stored in the Data Interchange for Materials Engineering (DIME) system as well. For your convenience, the HMA Mix Design input page contains a tab that is labeled "Sample and Test Summary" that contains links to all samples and test results on DIME.
Please visit DIME for more information.
The same requirements for Type A Hot Mix Asphalt, excluding RAP, should be followed with the addition of the following samples:
The same requirements for Rubberized Hot Mix Asphalt Gap Graded, excluding RAP and Hot Mix Asphalt, should be followed.
