Crack Surveying Methods to Evaluate Sealing Practice in Alaska

Abstract

It has long been suggested that a much more economical and sustainable approach be developed to address crack sealing effectiveness in Alaska. The development of a new method named special thermal crack evaluation (STCE) in a previous study served to directly and efficiently guide the crack sealing practices as opposed to the other nationally-used pavement surveying methods, including Long Term Pavement Performance (LTPP) and Pavement Surface and Evaluation Ratings (PASER). However, no or little research has been found to compare and correlate STCE with the other two methods. This paper presents a study to fulfill this research need. Further data interpretation showed that STCE was capable of guiding the decision-making on crack sealing practices, while the other two methods provided quantitative measurements and general rating of the sealed or non-sealed cracks. In addition, the correlation between STCE and the other two methods recommended that STCE better be used along with the other two methods for a better and more complete guidance on current or potential crack sealing practices.
