What type of asphalt is used on a dead level roof?

1. Type I asphalt

2. Type II asphalt

3. Gravel asphalt

4. Cricket asphalt

The correct answer is: Cricket asphalt

Cricket asphalt is a type of roofing material designed specifically for use on flat or low-slope roofs, known as dead level roofs. This type of roofing is essential because it addresses the challenges of water drainage that often accompany flat surfaces. A dead level roof does not have enough slope to allow water to run off effectively, making it prone to pooling if the right materials aren't used. Cricket asphalt includes provisions for ensuring that water is directed away from areas that may hold standing water, thus reducing the risk of leaks and water damage. A distinguishing feature of cricket asphalt is its formulation, which is generally designed to provide better waterproofing capabilities in scenarios where flat roofs require reliable performance against moisture intrusion. The application of cricket asphalt can significantly enhance the durability and longevity of the roof, ensuring that it can withstand various weather conditions without failing. Other types of asphalt listed, like Type I and Type II, relate to specific grades and temperatures for different applications rather than being dedicated to dead level roofs. Gravel asphalt typically involves a different construction method and is used for other purposes, primarily where a top layer of gravel protects the underlying asphalt from sun exposure and assists with drainage, but it is not specifically designed for flat roofs in the same way that cricket asphalt is.
