Specifications include, but are not limited to: The joint sealant shall be single component, fully reacted, homogeneous, hot applied, elastically modified and be ready for application when reaching the indicated pouring temperature. The joint sealant shall be composed of a mixture of materials that will form a resilient and adhesive compound capable of effectively sealing joints in concrete and asphaltic pavements against the infiltration of moisture and foreign material throughout repeated cycles of expansion and contraction with temperature changes, and that will not, at ambient temperatures, flow from the joint or be picked up by vehicle tires. The material shall be capable of being brought to a uniform pouring consistency suitable for completely filling the joints without inclusion of large air holes or discontinuities and without damage to the material. It shall remain relatively unchanged in application characteristics for at least 6 hours at the recommended pouring temperature in the field. It shall be suitable and intended for use in oil-jacketed melting equipment and capable of being pumped through a hose nozzle at operating temperatures between 350° and 380° F.
