A long-standing challenge in keeping an asphalt pavement from reaching its potential life is its longitudinal joints. Premature joint failures are the result of a combination of low density, permeability, segregation and lack of adhesion at the interface. Improving this component of our flexible pavement systems is one of the most important things we can … Continue reading Longitudinal Joint ...

Sealant is an ultra-low-modulus sealant that can be used to seal joints in asphalt pavements because it places very little stress on the asphalt joint face. Asphalt paving materials have low tensile strengths and require a sealant that places very little stress on the asphalt itself while keeping the joint sealed.

Cracks in pavement are the early phase of asphalt failure. Although asphalt is a flexible pavement, cracking is a normal occurrence. Cracks allow water to penetrate into the sub base which will eventually lead to pavement failure. Hot pour crack sealant is ideal for asphalt because it has superior elasticity, bonds well, and is black in color.
