Welcome feedback - Sawdust, sand, straw, dirt= ?

Would this be a hot mess or something wonderful?

I have 10 bales of old straw that need to be used, clay dirt, 4x50 gal trash bags of untreated wood sawdust, and I can buy some sand.  I’m wanting to make some raised beds for strawberries and asparagus as well as improve dirt where I’m gardening overall.  

Curious what the experts think and welcome feedback.

Are you meaning to mix it all and fill the beds with it?  I would personally compost the lot (not the dirt!) before using it, straw in my experience takes a long time to rot and sawdust has a irritating habit of clumping and going nasty. If you did want to compost straw and sawdust you would need to add a lot of greens or pee or some other form of nitrogen. I don't think that mixing it all into a raised bed and trying to plant anything would work well.
