Sealing or filling cracked asphalt pavements to prevent the intrusion of water into the pavement structure has long been an accepted practice of the Montana Department of Transportation (MDT). The goals of this research are to establish the most economical and effective method of sealing pavement cracks for Montana; and to better determine the role of crack sealing within Montana's pavement management system (PvMS). This study has involved the construction of four experimental test sites within larger crack sealing projects. These test sites have included combinations of eleven sealant materials and six sealing techniques. Monitoring of the test sites includes visual inspections (for all of the sites) and nondestructive structural readings and surface distress identification under Montana's PvMS (for one test location). An estimate of the useful life of each crack sealing method has been determined from these investigations.
