FINAL PROJECT REPORT:
DESCRIPTION: For this project, there will be multiple different field tests of the pavement markings to determine the safety evaluation. There will first be a qualitative bike and motorcyclist rider evaluation survey to determine the slippage of marked roadways under different conditions. The same locations will also be tested using a British Pendulum Tester (BPT) to collect quantitative data. The qualitative and quantitative data will then be compared using field data. Square one-foot slabs will also be tested in the laboratory using the BPT. Each of the tests for the qualitative and quantitative data will be evaluated under different degradations of the pavement markings as well as different surface conditions (dry, wet, and ice). The degradations will be evaluated in the field to find different levels while the laboratory testing will use a wheel abrasion tester to degrade the markings to different levels.
