Answer :
Final answer:
The correct ASTM specification for clay brick pavers used in pedestrian walkways is ASTM C902. This specification outlines essential criteria like com pressive strength, water absorption, and freeze-thaw cycle resistance to ensure the pavers' durability and safety. Thus option C) ASTM C902 is correct answer.
Explanation:
The requirements for clay brick pavers used in pedestrian walkways are delineated in ASTM C902. This specification outlines the physical and aesthetic qualities necessary for clay pavers to ensure durability, safety, and compatibility with the pedestrian environments where they are installed. It includes criteria such as compressive strength, water absorption, and resistance to freeze-thaw cycles, among others. This ensures the pavers can withstand the rigors of weather, wear, and other external factors that could compromise their longevity and performance in pedestrian areas.
