- 850 - SECTION 1030 -- LIQUID ASPHALTS
1030.01 Description
1.Medium-Curing Cutback Asphalt is the accepted Department’s liquid asphalt.
1030.02 Material Characteristics
1.Cutback asphalts shall conform to t he AASHTO M 82, Medium- Curing Type requirements with the following changes:
a.Note “a” of Table 1 is void. b. Note “b” of Table 1 is amend ed to read: In lieu of viscosity of the residue, the Department specifie s the test of penetration with a specification of 120 to 250 dmm for all grades.
c.Due to the advent of low-sulfur petroleum formulations, some of which are used as diluent in the fluxing of cutback materials production, the Table 1 test requirements of Flash Point (tag, open cup), and Distillation, percent by volume of total distillate at the temperatures of 225 oC (437oF) and 260oC (500oF), are removed.
1030.03 Procedures
1.Medium-Curing cutback as phalts shall be stored, heated, transferred, or otherwise handled, as per Manufacturer’s recommendations.
