As illustrated in Fig. 10, adding basalt fiber to the matrix asphalt increased the three moduli, with an increase of 7.9% in elastic modulus, 1.3% in bulk modulus, and 6.1% in shear modulus. This indicates that the micro-mechanical properties of basalt fiber-reinforced asphalt are enhanced, but the increase is not obvious.
However, when samples are water saturated, the bulk modulus of the rock is frequency dependent. Modeling with Gassmann's equations predicts the measured saturated rock bulk modulus for all fluids for frequencies below 20 Hz but underpredicts the water-saturated basalt bulk modulus for frequencies greater than 20 Hz.
The isothermal bulk modulus K T and the pressure derivative of the bulk modulus K′ of the melt differ from the values obtained by Circone and Agee (1996): K T = 15.5 GPa and K′ = 5.2 at 2173 K. This result indicates that the high-Ti basalt melt is more compressible than previously reported.
