The data listed below, covers the four ASTM D312-89 grades of asphalt currently being shipped from our Wynnewood, Oklahoma operation.

APPENDIX XI.

SLOPE GUIDELINES

 Xi.1 This appendix covers suggested slope guidelines for the four types of asphalts. However, no restrictions are implied or intended on the slope at which a specific type of asphalt must be used. These guidelines may be modified to whatever degree is justified by the familiarity and experience of those skilled in the art of build-up roofing construction and performance as well as with local roofing practices and local weather conditions. For example, modifications from the suggested guidelines may be made depending upon: the type and occupancy of the building; the nature of the roofing components and the roof system construction including type and thickness of insulation; the application procedures, including the experience and competency of the roofing crew; and the roofing specification, including nailing requirements. Other considerations may include but should not be restricted to the chemical and theological properties of the asphalt: the type and character of the felt or fabric used: the amount of asphalt used between plies: the color, type, and mass of surfacing: and the direction of exposure. Keeping in mind these considerations and that no restrictions are intended on the slope, at which specific asphalt must be used, the following guidelines are provided.

Xi.1 Type I includes asphalts that are relatively susceptible to flow at roof temperatures with good adhesive and "self-healing" properties. They are generally used in slag- or gravel-surfaced roof on inclines up to 4.17% (1/2 in./ft.) slope.

Xi.2 Type 11 includes asphalts that are moderately susceptible to flow at roof temperatures. They are generally for use in build-up roof construction on inclines from approximately 4.17% (1/2 in./ft.) slope to 12.5% (1 1/2-in./ft.) slope.

XI. 3 Type III includes asphalts that are relatively nonsusceptible to flow at roof temperatures for use in construction of build-up roof construction on inclines from approximately 8.3% (I in./ft.) slope to 25% (3 in./ft.) slope.

XI. 4 Type IV includes asphalts that are generally nonsusceptible to flow at roof temperatures for use in the construction of build-up roofing an inclines from approximately 16.7% (2 in./ft.) slope to 50% (5 in./ft.) slope. These asphalts may be useful in areas where relatively high year-round temperatures are experienced.
