Microstructure in Adhesion Development Process and Strength Formation Mechanism in Early Stage of Cold Recycled Mixture with Emulsified Asphalt

Table 4

Effects of influencing factors on CRME [14, 28, 62, 87, 91, 93].

Influencing factors		Effects
Curing temperature		The high temperature would accelerate curing.
Curing humidity		Cured in sealed conditions (high humidity) exhibited a slower curing rate and a higher long-term performance.
Materials	Cement dosage	Increasing it would increase the indirect tensile stress (ITS), the high-temperature stability and moisture susceptibility. CRME had better low-temperature cracking resistance with 1%–2% cement.
	Emulsified asphalt dosage	Increasing it would increase the resistance against rutting and fatigue.
	Water content	The right amount of water is conducive to the compaction.
	Aging degree of aged asphalt of RAP	It has a negative effect on the strength formation.
Compaction		The higher compaction power is beneficial to strength formation.
