By embedding electrodes into it as it sets, Yucan measure changes in electrical resistance to detect compression frompassing cars.
通过事先在混凝土中植入电极，余教授可通过测量电阻的变化而得知过往车辆对路面的挤压情况。

Excellent resistance to oil, high temperature resistance, weather resistance are good, but the mechanical strength, compression deformation rate and water resistance is slightly worse.
对油品有极佳的抵抗力，耐高温、耐候性均佳，但机械强度、压缩变形率及耐水性稍差。
