ASTM D2027 Standard Specification for Cutback Asphalt (Medium-Curing Type)
1. Scope
1.1 This specification covers cutback petroleum asphalts of the medium-curing type for use in the construction and treatment of pavements.

1.2 The values stated in SI units or inch-pounds are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of each other. Combining values from the two systems may result in non-conformance with the standard.

3. Properties
3.1 The cutback asphalt shall not foam when heated to application temperature and shall conform to the requirements prescribed in Table 1.

4. Test Methods
4.1 The materials shall be sampled in accordance with Practice D140, and the properties enumerated in this specification shall be determined in accordance with the following ASTM test methods:
4.1.1 Flash Point (Tag Open-Cup) - Test Method D3143.

4.1.2 Viscosity, Kinematic - Test Method D2170.

4.1.3 Viscosity, at 60°C [140°F] - Test Method D2171.

4.1.4 Distillation - Test Method D402.

NOTE 1 - If a 100-mL graduate does not permit sufficiently close readings to determine conformity to this specification with the desired accuracy, receivers graduated with 0.1-mL divisions shall be used.

4.1.5 Penetration - Test Method D5.

4.1.6 Ductility - Test Method D113.

4.1.7 Solubility in Trichloroethylene - Test Method D2042.

4.1.8 Water - Test Method D95.
