Abstract:
To address the issue of water infiltration and debris retention, bi

tuminous 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 mu

st 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 rigo

rous 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 fil

led 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 a

pplying 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
