Low-Rate Ice-Scraping Tests

Abstract

A series of experiments were conducted to determine the force required to scrape ice from portland cement concrete (PCC) and asphaltic concrete (AC) samples. The force was measured as a function of cutting-edge geometry (especially rake angle), the scraping velocity, and the applied download. The results indicate that the rake angle has no significant effect on the scraping force, whereas the download has a clear effect, with scraping force increasing with download. An increase in the scraping rate caused the scraping force to decrease for the PCC samples, but not for the AC samples. The results are compared with those obtained for negative rake angles in another study.
