Scope

The traditional Marshall compaction design may cause over- or under-compaction of the specimens, which in turn affects the compaction quality of asphalt mixtures. The improved method of determining the locking state of asphalt mixtures, with the locking point as the main control indicator, enables the acquisition of asphalt mixture specimens with better voidage, effectively reducing the damage to the framework caused by possible over-compaction, optimizing the design of asphalt mixture ratios, extending the service life of asphalt pavements, saving funds for asphalt pavement maintenance, improving the quality of construction compaction operations, enhancing the economic and social development benefits, and maximizing the road performance.
