Abstract:
Asphlat roof shingle is a roof covering, widely used for waterproofing. The composite is made up of fiberglass which is implied as the base and a coating of mixture of asphalt and limestone over the base. Ceramic granules are sprinkled to the top.
Traditional roofing materials in Pakistan are costly, require periodic replacement and are prione to corrosion. Therefore, these singles are are presented as an alternative to these materials due to relatively lower up-front costs and easy installation.
With the variation in the amount of limestone in the composite, several different samples were tested according to ASTM standards. According to these standards, it is safe to say that as the amount of limestone increased, the strength, waterproofing, tear resistance, fire proofing and wind resistance increased.
