| Description | In recent years, significant advances in both materials and methods for sealing cracks in asphalt concrete pavements have been made. Crack sealing has transformed from a poorly performing, and many times ineffective "fill in type of maintenance task, to a viable and cost-effective preventative maintenance technique which can extend the life expectancy of roadways. This paper examines the many aspects of the maintenance technique of sealing cracks in asphalt concrete pavements. The subject is covered by qualitatively examining the cracking mechanism and 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 which 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 which are used in crack sealing. |
