Abstract:

In an attempt to reduce reflective cracking on overlay projects a study was conducted that consisted of sealing all transverse cracks greater than ¼ inch with hot crack sealers before the project was resurfaced. The experiment will evaluate the effectiveness of two types of crack sealants and two methods of crack sealing. One method was simply to fill the cracks while the other method required routing and filling the cracks. The two sealants used were asphalt with fibers and asphalt with rubber. These four options were compared against two “Control Sections” where no crack preparation was performed prior to paving.
