• Abstract:
  To address the issue of water infiltration and debris retention, bituminous crack sealers and fillers have been ; developed to help prevent premature pavement distress. If applied appropriately, crack sealers and fillers can ; significantly extend the life of a pavement. To utilize crack sealers and fillers properly, one must understand that ; sealers and fillers differ in application and material types. Crack sealers are typically used on cracks that move ; more than one-eighth inch, with the intention to prevent water and debris from entering the pavement structure. ; The rigorous installation process involves thorough crack preparation followed by placement of high elongation ; material in a specific configuration. Crack fillers generally use a stiffer material than crack sealers and are typically ; used on non-working cracks ; The purpose of this study was to examine and evaluate the constructability, overall performance and cost ; effectiveness of AASHTO M324-12 Type II versus IV Joint Sealers. Research personnel assessed each product’s ; durability at each location. Cracks were filled according to the project plans. Efforts were made to provide a ; comparative analysis with regard to performance and cost of both material types by minimizing application ; variations in weather conditions, equipment used, and application crewmembers by applying material on the same ; day and/or conditions. ; Over a three-year span and six data collection timeframes, the type IV material resulted in an average of a ; 10% less allowance of water passage through the length of a filled crack. A ten percent better performance of a ; material over a comparable alternative is considerable and should not be ignored, and results in approximately 2 ; feet less of compromised length of a full width transverse crack.
