Asphalt For Constructing Built-Up Roof Coverings And Waterproofing Systems
Scope:
This Standard covers asphalt intended for use as hot cement and topcoat in the construction of built-up
coverings on roof decks of various types and slopes and in the construction of waterproofing systems.
1.2
The following types of asphalt are covered by this Standard:
(a) Type I: asphalt for use on built-up roofs with slopes less than or equal to 1:16 and for use as
waterproofing below ground level when not exposed to surface temperatures above 25 ºC (77ºF).
(b) Type II: asphalt for use on built-up roofs with slopes less than or equal to 1:8 and for use as
waterproofing above ground level on vertical surfaces not exposed to direct sunlight.
(c) Type III: asphalt for use on built-up roofs with slopes greater than 1:8 for exposed applications or for
use as waterproofing above ground level on vertical surfaces not exposed to direct sunlight.
