Antiaging Property and Mechanism of Phase-Change Asphalt with PEG as an Additive

Table 1

The physicochemical parameters of PEG-1000.

	Relative molecular weight	T0n (°C)	(°C)	Tend (°C)	(J/g)
PEG (1000)	950∼1050	29	45.6	76.7	78.6

Note. T_0n: initial temperature of phase transition; : phase change temperature peak; T_end: phase transition termination temperature; : enthalpy of phase change.
