Abstract:
This Q&A focuses on comparison of a level straightedge used when performing ASTM E1155 or ASTM E1486 testing versus a manual straightedge used in the manual straightedge method described in ACI 117-10(15). Additional information on requirements related to performing the manual straightedge method is also provided.
