Hypothesis
What are the cumulative strain and improvement mechanisms of soil reinforced by xanthan gum biopolymer under traffic loading?
Conclusion
The study found that xanthan gum biopolymer significantly reduces cumulative strain in soil, especially with optimal content and curing time.
Supporting Evidence
- The cumulative strain decreases from 3.65% to 1.77% as the curing time increases from 1 day to 28 days.
- As the moisture content increases from 13.3% to 19.3%, the cumulative strain experiences an 853% increase.
- Specimens with higher xanthan gum biopolymer content show better resistance to loading.
Takeaway
Using a special natural substance called xanthan gum can make soil stronger and less squishy when cars drive over it.
Methodology
Laboratory tests including cyclic triaxial tests and scanning electron microscopy (SEM) were performed to analyze the effects of xanthan gum biopolymer on soil.
Limitations
The study may not account for all environmental conditions affecting soil behavior in real-world applications.
