| 摘要 |
A skid-resistant pavement marking sheet including a top surface (20) and a plurality of skid-resistant ceramic spheroids (22) embedded in and protruding from the surface (20). The ceramic spheroids (22) are fired from a raw material mixture including 10-97 wt. % mineral particulates, 3-90 wt. % alumina, and at least 1 wt. % binder, at a temperature of about 1300 DEG C, have an outer surface rich in alumina concentration relative to the center of the spheroid, and are resistant to crushing and fracturing. |
