What is the optimum water content of clay and what are the factors that affect the compaction effect of clay?
1. The main influencing factors of soil subgrade compaction are as follows: 1. Soil quality: Different types of soil have different compaction properties. As far as filling compaction is concerned, gravel soil, sandy soil and sandy soil are the most suitable, and the compaction effect of clay is the worst. 2. Water content: the compaction effect of soil is related to the real-time water content, and there is an optimal water content w.
