Before You Start
Gather the following before opening the concrete submittal form. You will need project details, lab-tested mix design calculations, and material test reports. Collect current certifications for cement, fly ash, and each admixture type as well. Submitting outdated certifications is the most common reason for rejection.
The form covers five main sections: project information, mix proportions, fresh concrete properties, hardened concrete properties, and aggregate data. Review each section header before you begin.
Using the online PDF editor at FormsPal, you can fill out or edit the concrete mix design submittal right here. Follow these steps to complete the form:
Step 1: Click the orange "Get Form" button above. This opens the PDF editor so you can begin filling in your form.
Step 2: Once you open the editor, the document is ready to fill out. You can fill in fields, edit text, add images, and add your signature.
Here are the specific instructions for each section:
1. Complete the first section carefully. Fill in all of these fields: project name, contractor name, subcontractor, date, concrete class, and exposure class.
2. Move to the fresh concrete properties section. Complete these fields: Total air, Totals, Hydration Stabilizer B or D, Other, FRESH CONCRETE PROPERTIES, Theoretical unit mass, Measured air, Measured slump AASHTO T, Average day strength, Signature, Print Name, Design in, Date, Form FHWA Rev, and Page of. Review each entry before continuing.
3. The third section covers cementitious materials and admixtures. Complete these fields: STRUCTURAL CONCRETE MIX DESIGN, CEMENT AASHTO M TYPES I IA II, WATER AASHTO M AND AASHTO T, Reclaimed water or water of, CHEMICAL COLOR PIGMENTS FIBERS AND, Admixture Type, Air entraining AASHTO M, Point Admixture, Added, Certification Attached, and the four Yes/No checkbox rows.
4. The fourth section covers admixture types in detail. Fill in: Type A Water reducing, Type B Set Retarding AASHTO M, Type C Set Accelerating AASHTO M, Type D Water Reducing and Set Retarding AASHTO M, Type E Water Reducing and Set Accelerating AASHTO M, Type F High Range Water Reducing AASHTO M, Type G High Range Water Reducing and Set Retarding AASHTO M, Type B Hydration Stabilizing AASHTO M, Type D Hydration Stabilizing, and hours.
5. The final section covers fine aggregate data. Complete all required fields: FINE AGGREGATE FP SECTION AND, Location of material source, Natural sand Blend, Sieve Analysis AASHTO T, Property, Specification, Value, Sieve Size, Passing P, Cumulative, Clay lumps and friable AASHTO T, and Specification. Leaving any field blank may result in an incomplete submittal.
Pay close attention to the Sieve Analysis AASHTO T and Passing P fields. These are key data points in the document. Errors here are grounds for rejection.
Step 3: After reviewing all fields, click "Done." Download or print the completed form. A free trial account saves your progress and lets you return to the concrete mix design submittal at any time. At FormsPal.com, all of your details are kept secure.
Tips for an Accurate Concrete Submittal
Always use current, lab-tested data for mix proportions. Field estimates will not be accepted. Submit test reports dated within the past 12 months unless your contract specifies otherwise.
Check your water-to-cementitious materials ratio against the specification maximum. This is one of the most commonly rejected items. The calculated ratio in the form must match the batch weights exactly.
Attach all certifications before submitting. Cement, fly ash, silica fume, and each admixture type need separate manufacturer certifications. Missing attachments are the leading cause of resubmission requests on federal projects.
Verify aggregate gradation against your project specifications. Use the exact sieve sizes listed in the contract documents. Gradation outside the specified limits requires a full mix redesign and resubmittal.
Frequently Asked Questions
What is a concrete submittal form?
A concrete submittal form documents a proposed concrete mix design for engineer review and approval. It lists all materials, proportions, and expected performance values. The engineer must approve the submittal before concrete placement can begin.
What is FHWA Form 1608?
FHWA Form 1608 is the official concrete mix design submittal form for Federal Lands Highway projects. It is published by the U.S. Department of Transportation. The form is also called the 552 Structural Concrete Mix Design Submittal and is commonly referenced as the 1608 AASHTO online form.
How long does concrete submittal approval take?
Most federal highway projects require the concrete mix design submittal at least 30 days before planned placement. Some agencies require 45 to 60 days for complex structural mixes. Submit early to avoid delays in your construction schedule.
Can I resubmit a rejected concrete submittal?
Yes. Address each comment from the reviewing engineer before resubmitting. Label the revised submittal with a new revision number. Include a written response that identifies every change you made to the original concrete submittal form.
What materials need certifications in the concrete submittal?
Cement, fly ash, ground slag, silica fume, and all chemical admixtures require manufacturer certifications. Aggregates may also require certified test reports depending on your project specifications. Check the contract documents for the complete list.
