Study on the Evaluation Standard of Construction Quality for Asphalt Pavement Based on the Intelligent Sensing Aggregate

Table 12

Evaluation standard of construction quality for asphalt pavement based on DPI.

Construction quality	Excellent	Good	Medium	Inferior	Bad
Value ranges of DPI (°)	≤4.7	>4.7, ≤6.8	>6.8, ≤7.9	>7.9, ≤9.6	>9.6
Matters needing attention	(1) When the construction quality is “excellent” level, it must also meet the condition of  ≤ 5° after the completion of road compaction
	(2) The test mileage of DPI should not be less than 5 km and increased the testing times in the same lane when the test mileage is less than 5 km
