Resilient modulus of elasticity

Sulfui>-Aggregate Interaction. Substantial increases in stiffness of SA binder-based mixes, as measured by the Marshall test, tensile strength, and resilient modulus of elasticity, have been observed with increasing sulfur-asphalt ratio of the binder used (11, 15, 16). Such increases can, of course, be attributed in part to the increase in viscosity of the SA... 

Resilient Modulus of Elasticity. The addition of sulfur produced an increase in stiffness in terms of resilient modulus of elasticity, Figure 9. Generally this increase required the addition of 50% sulfur, although in some cases 20% sulfur produced a substantial increase.
