MATERIALS AND METHODS FOR SEALING CRACKS IN ASPHALT CONCRETE PAVEMENTS
In recent years significant advances in both materials and methods for sealing cracks in asphalt concrete pavements have been made. Crack sealing has been transformed from a poorly performing and many times ineffective fill-in type of maintenance task to a viable and cost-effective preventive maintenance technique that can extend the life expectancy of roadways. Many aspects of the maintenance technique of sealing cracks in asphalt concrete pavements are examined herein. The subject is covered by qualitatively examining the cracking mechanism and the consequences of not maintaining adequately sealed cracks. The influences of climatic conditions and traffic on crack formation and subsequent movements are discussed. Physical characteristics of sealant materials required for application and acceptable performance are discussed, as well as testing methods for determining these characteristics. Physical properties and specification conformance of materials that are currently used as crack sealants are presented. Advantages and disadvantages of two basic types of sealant application configurations are discussed along with equipment and application methods that are used in crack sealing.
