ASTM D6927 (Standard Test Method for Marshall Stability and Flow of Asphalt Mixtures)

ASTM D6927 is a standard test that measures the strength and deformation behavior of asphalt mixtures used in pavement. Using a specialized machine, a sample is compressed until it stabilizes (Marshall Stability), and the amount it deforms (Flow) under pressure is recorded. This test helps engineers evaluate the quality and durability of asphalt mixes, ensuring they can withstand traffic loads and environmental conditions. It provides consistent, reliable data to optimize pavement design and construction, ultimately enhancing road safety and longevity.
