| Outline of Final Research Achievements |
I studied the reversible gel which contains nanosilica particles and poly(ethylene glycol) aqueous solutions. I focused on the cost reduction of this sample and found that this sample gelated at lower shear rate by added small amount of NaCl or different size silica particles. In addition, I put a bag with reversible gel sample under the soil and pave it by wood-chip. There is no significant difference between static friction coefficients of roads with gelated and not gelated samples. And when I measured the reflection coefficient of wood-chip pavement road with reversible gel by dropping the golf ball, the coefficient increased by kneading the bag of the sample. From these results, the road becomes harder by running on it fast.
