Development of an Asphalt Pavement Raveling Detection Algorithm using Emerging 3-D Laser Technology and Macrotexture Analysis
| 项目名称： | Development of an Asphalt Pavement Raveling Detection Algorithm using Emerging 3-D Laser Technology and Macrotexture Analysis |
| 摘要： | This project will develop and demonstrate the application of an asphalt pavement raveling detection system based on an algorithm developed using three dimensional (3-D) laser technology and macrotexture analysis. Work in Stage 1 will focus on developing the automatic raveling detection algorithm. Raveling, as defined by different transportation agencies, will be reviewed, including any quantitative definitions. All past studies on automatic raveling detection will also be reviewed. Following the review, a raveling detection algorithm based on raveling as defined by Georgia and other state departments of transportation (DOTs) will be developed. The work will be performed in close association with Georgia DOT to quantify the measurement of raveling with different severity levels based on current DOT practices. Work in Stage 2 will involve validation and refinement of the developed algorithm. Working with collaborating transportation agencies and industry partners, data for algorithm's validation and refinement will be collected. For the validation test, a manual survey will be conducted on selected reference sites with different levels of raveling severity. The pavement 3-D laser data will also be collected using a sensing vehicle. One set of the reference sites will be used as the ground truth to establish the thresholds for the raveling detection algorithm while another set of reference sites will be used for algorithm validation. The developed algorithm and its application will be validated working with collaborating DOTs and industry partners. The final report will provide all relevant data, guidelines and specifications for the raveling detection system and plans for its implementation by highway agencies. |
