27、e viscosity of the original asphalt cement may be substituted for dynamic shear measurements of G*/sin at test temperatures wherethe asphalt is a Newtonian fluid.

28、1).D The PAVAging temperature is based on simulated climatic conditions and is one of the three temperatures 90C, 100C or 110C. The PAV aging temperature is 100C for TLG 64- and above except in desert climates,where it is 110C.E Physical HardeningD6648 is performed on a set of asphalt beams accordin
29、g to section 13.1, except the conditioning time is extended to 24-h 10 min at 10 C above the minimum performance temperature. The24-h stiffness and m-value are reported for information purposes only.F If the Creep stiffness is below 300 MPa, the direct tension test is not required. If the creep stif
30、fness is between 300 and 600 MPa the direct tension failure strain requirement can be used in lieu of the creep stiffnessrequirement. The m-value requirement must be satisfied in both cases.D66261535.3 The base asphalt binder shall be homogeneous, free from water and deleterious materials, and shall
