Preparation, Structure, and Properties of Modified Asphalt with Waste Packaging Polypropylene and Organic Rectorite

Table 1

The properties of petroleum pitch, WPP, and OREC.

Raw materials	Properties
Asphalt	C/H	TI (wt. %)	QI (wt. %)	SP (°C)
	0.73	13.6	0.1	51.3
WPP	Basis	Purity	Density (g/cm^3)	SP (°C)
	PP	93%	0.91	134.5
OREC	d(001) (nm)	Purity	Specific surface area (m^2/g)	Average diameter (nm)
	3.2	85%	87	180

Note. C/H: atomic ration; TI: toluene insoluble; QI: quinolone insoluble; SP: softening point; d₍₀₀₁₎: interlayer spacing of (001).
