Component

The flexible pavement is the most used for the coating of roads due to its numerous advantages. However, the main disadvantage is the appearance of cracks on the surface, which if they are not treated in a timely manner can cause damage to the infrastructure and reduce the efficiency of the same. Therefore, the cracks should be treated effectively. The method of sealing of cracks is highly used in flexible pavements, but has some difficulties, which is why sealing materials must present characteristics of adhesion, hardness, and resistance to water filtration. The present paper shows the development of a sealant based resin epoxy, which was placed on a stretch of test and subjected to weathering, allowing to know in this way its behavior. The results obtained show that in the conditions of weathering to which was submitted the sealer, this has an acceptable behavior, decreasing by 20% the intrusion of water to layers underlying, besides a null loss of groups functional present.

This paper was sponsored by TRB committee AHD25 Standing Committee on Sealants and Fillers for Joints and Cracks. Alternate title: Characterization of a Material Sealant for Cracks in Pavements Flexible.
