Theoretical maximum density asphalt
Webb1.Introduction. Adequate field density is essential for the load-bearing capacity and the durability of asphalt pavements [1], [2], [3].The current field density level in the U.S. is about 93 ∼ 94 % of the theoretical maximum density (G mm) [4], [5], which is believed as inadequate and the main cause for the occurrence of many premature durability-related … WebbAnnexure I Outline of AASHTO T 283, “Resistance of Compacted Asphalt Mixtures to Moisture-Induced Damage” 18 Annexure II Outline of ASTM D 2041, “Theoretical …

WebbThe ideal compaction range is typically between 92%- 98% of the theoretical density. As the pavement is being placed, there are several methods of testing asphalt pavement for compaction. The most common method is a Nuclear Density Gauge. The gauge measures compaction as the pavement is placed. WebbNominal Maximum* Aggregate Size mm (in.)
