Astm D560 ^new^ May 2026

Introduction ASTM D560 (alongside its metric counterpart D560M) is arguably one of the most critical test methods in geotechnical and pavement engineering. Developed in the mid-20th century during the boom of soil-cement stabilization for roads and airfields, this standard provides a procedure for evaluating the resistance of compacted soil-cement to repeated cycles of freezing and thawing. In simple terms, it answers the question: “Will this soil-cement mixture survive a harsh winter?”

This review examines the test’s methodology, practical strengths, limitations, and its relevance in modern construction. astm d560
