6、ectively sealing joints and cracks in concrete andasphaltic pavements against the infiltration of moisture andforeign material throughout repeated cycles of expansion andcontraction with temperature changes,and that will not,atambient temperatures,flow from the joint or be picked up byvehicle tires.
7、The material shall be capable of being brought toa uniform pouring consistency suitable for completely fillingthe joints without inclusion of large air holes or discontinuitiesand without damage to the material.It shall remain relativelyunchanged in application characteristics for at least 6 h at th
