Compaction standard still the heavy compaction Standards Act, indoor compaction test exceeded the particle size is controlled within 5%, however, the in situ process the super particle size content is greater than the the super particle size of the standard compaction when content, which brings certain difficulties for compaction control. Another standard indoor compaction method (heavy compaction) 8t ~ 15t when using the corresponding good, but now 20t even the greater tonnage roller highway construction has been commonly used in the compactor tonnage. Obviously indoor compaction standards already can not keep up with the the road rollers development requirements. Since the compactor tonnage,Scene subgrade compaction compaction energy increases, compaction standard unchanged, the degree of compaction "super 100" phenomenon may occur.
