The clay is the glue which holds together the sand and the straw. Its main ingredient is aluminum salt. Aluminum salt is composed of very fine particles. The options are endless when it comes to clay types to use but the highest success is found with clay loam or sandy clay. If the soil to create the adobe brick contains too much clay it will crack. Sand can be added to the mixture when the clay ratio exceeds the code approval. After your mixture is complied a soil test is needed.
Lastly, the asphalt acts as a sealant to keep water out. Thus making the adobe brick water resistant. This helps the adobe structure from weather damage. It permits the structure to stand for many years and is why we still have century old adobe buildings still long-standing today.
