I created a mixture of mixtures test plan. Now that the data are collected, I'm not sure how to interpret the results. Can I get help to verify that I designed the experiment correctly, and also walk me through how to interpret the results?
I am studying the friction of asphalt surfaces, and specifically the effects of aggregate type, aggregate blend ratios on coarse and fine fractions, and asphalt gradation type.
Aggregate Types, 6 total:
- Class A (high quality): A1, A2, A3
- Class B (low quality): B1, B2, B3
Aggregate Blending (Coarse and Fine portions)
- Blend percent of Coarse Class A and B aggregate in total mix: 0 to 50%
- Blend percent of Fine Class A to B aggregate in total mix: 0 to 50%
- Total of Coarse and Fine = 100%
Gradation Type, 2 types
- Type C
- Type D
Attached is the custom design and results.
Here's the Effect Summary. Some questions: if the blend percentage of Coarse_Class A and Class B are the inverse of eachother, are the effects independent? How do I see effects of just the agg types (A1, A2, A3, vs B1, B2, B3)? I've got more questions, but can't get my bearings straight. THANKS!
