The E D X spectra labelled a and b present elemental composition with counts on the vertical axis and energy in kilo electron volts on the horizontal axis from 0 to 10. Spectrum a represents the control mixture, with labelled peaks including S i, O, Na, B r, M o, K and Ca at lower energy levels. Spectrum b represents the modified asphalt mixture with 50 percent S D A plus C C A, with prominent peaks including Al, S i and M g, with higher intensity at lower energy values. Instrument settings and acquisition details appear along the lower edges of both spectra.EDX Of (a) control mixture and (b) modified asphalt mixture (50 Wt. % SDA and CCA)
