Emission Reduction Performance of Modified Hot Mix Asphalt Mixtures

Table 3

Emission reduction rates of different types of modified asphalt.

Dosage of modifier (%)	WEAM modifier			WES modifier			WEP modifier
	15	20	25	15	20	25	20
Emission reduction rate (%)
NOx	39.61	65.93	69.25	42.11	65.37	67.04	63.71
COx	40.45	70.50	78.09	37.08	64.89	70.20	61.80
