This report summarizes the analysis of transverse cracking in asphalt pavement by a five state study team from Iowa, Kansas, Nebraska, North Dakota, and Oklahoma. The study was initiated under the sponsorship of the Federal Highway Administration and four evaluation conferences were held during the course of the study. Each state conducted a crack inventory on their asphalt pavement. An effort was made to correlate this inventory with numerous factors that were considered to be pertinent to the cracking problem. One state did indicate that there was a correlation between transverse cracking severity and the subsurface geology. The other states were unable to identify any significant factors as being the primary contributors. The analysis of the problem was divided into, (1) mix design, (2) maintenance, and (3) 3R rehabilitation. Many potential factors to be considered were identified under each of these three study divisions.

A recent two-year research study compared clean-and-seal asphalt pavement crack repairs to rout-and-seal repairs. The life-cycle cost analysis found rout-and-seal repairs to be slightly more cost-effective. Researchers also developed two decision trees for selecting a repair method. This project will help implement the results of that study by developing an easy-to-use quick reference guide summarizing the results of the study and an informational video on the crack-sealing techniques.

This study investigated the current state of practice for crack sealing/filling. In addition, the INDOT crack sealing/filling practice was experimentally evaluated for the effectiveness of crack sealing/filling, the effectiveness of routing, the performance of the different types of crack sealants and fillers, the validity of sealant performance grade system, and the crack sealing/filling equipment performance. The key findings from an extensive literature review and nationwide/statewide survey performed in 2012 are the following: (1) 65% of the responses indicated that the routing is required for the crack sealing/filling application; (2) ASTM D 6690 Type II was the most widely used sealant type and only Missouri and Indiana included emulsions in their specifications as crack sealing/filling materials; and (3) crack sealing/filling equipment availability and their maintenance were the biggest concerns.Based on the two-year experimental investigation, the crack sealing/filling was determined to be effective in preventing the occurrence of pavement surface crack distress. The crack sealing/filling was concluded to be effective in maintaining crack integrity and resisting sealant and filler deformations due to the seasonal crack movement. The routing was not determined to be effective in terms of the pavement performances. However, Adhesive/Cohesive/Spalling (ACS) failure results showed that the routed sections significantly outperformed the non-routed sections. In addition, the test results indicated that the ASTM 6690 Type II crack sealants performed relatively well in terms of pavement and crack performance. The correlation between the sealant performance grades and the pavement and crack performances with different types of sealants and fillers were poor and insignificant.The experimental results showed that the cracks on wet pavement treated with HAL had significantly higher bonding between the materials and asphalt pavement surface than the cracks treated with the conventional air compressor. Therefore, the incorporation of a hot air lance in the wet condition is recommended to extend the operable time and seasonal availability for crack filling and sealing construction (2070 and 2090 Activities).
