ANOVA p-values for microwave heating and energy consumption of the raw materials.

Variable	p-Value	Statistically Significant Differences?	Tukey HSD Mean Comparisons
Heating	<0.001	Yes	CA-B; CS-B; FS-B; MF-B
Energy	<0.001	Yes	CA-FS; CA-MF; CA-B CS-FS; CS-MF; CS-B

Notes: CA: coarse aggregate (12.5–5 mm); CS: coarse sand (2.5–0.32 mm); FS: fine sand (0.16–0.08 mm); MF: mineral filler (<0.08 mm); B: bitumen.
