  • To evaluate the quality of the foamed mixture lightweight filler subgrade, field tests were performed based on ultrasound technology in a practical project. Wave velocity, amplitude and main frequency were selected as evaluation indicators, and a novel method for detection and evaluation of foamed mixture lightweight filler subgrade was established. Evaluation method consisted of two steps: the first step judged whether the on-site subgrade was qualified by evaluation indicators; the second step evaluated quality grade of the qualified subgrade by entropy weight-based subgrade quality uniformity evaluation model. The results show that when testing distance is 0.8 m, the ultrasound test results of the foamed mixture lightweight filler subgrade are stable and representative. 95% of minimum wave velocity, 80% of average amplitude and 86% of average main frequency can be used as the low limits to judge whether the subgrade is qualified. The evaluation results show that the test section subgrade is qualified, and the subgrade quality grade is good.
