Next Generation Crack Sealing Planning Tool for Pavement Preservation

As one of the most popular preventive maintenance methods, crack sealing and filling (CS/CF) has been widely used by state highway agencies. Due to stringent highway budgets and the lack of work forces in state highway agencies, it is urgent that CS/CF, as well as other types of pavement preservation methods, be incorporated in a pavement management system (PMS). For this purpose, this research project proposed a systematic framework to study the cost-effectiveness of CS/CF and incorporate CS/CF planning in a PMS. Three key research objectives have been investigated: 1) to propose an accurate workload estimation method using 3D laser data and automatic crack detection and crack width measurement method, 2) to propose a quantitative methodology to objectively evaluate CS/CF effectiveness, and 3) to propose a Fisher-clustering-algorithms-based pavement segmentation method to partition a pavement network into individual CS/CF projects. The proposed methodology has been evaluated using different case studies and has demonstrated promising results. It is hoped this research project will advance the state-of-good-repair practices for asphalt pavement crack sealing into the next generation to prolong the life of pavements.
