702.01 Bituminous Materials
A.Furnish bituminous materials in accordance with following tables. Cationic Emulsified Asphalt ............................... AASHTO M 2081, Table 1 Emulsified Asphalt ............................................. AASHTO M 1401, Table 1 High Float Emulsions......................................... Table 702-4 Medium Curing Liquid Asphalt (MC) .................. Table 702-3 Performance Graded Asphalt Binder ................. Table 702-2 MSCR PGAB ............................................... AASHTO M 3322 Polymer-Modified Cationic Emulsified Asphalt ... AASHTO M 316 Notes: 1. Cement mixing test does not apply when SS-1 or CSS-1 emulsion is used for spray or tack application.
2.Minimum 55% recover @ 3.2 kPa according to AASHTO T 350 or as specified in the contract. Meet the requirements for bituminous materials in accordance with the contract.
B.Polymerize CRS-2P emulsions using at least 3% polymer by weight (mass) of the asphalt binder.
702.02 Testing and Acceptance
Bituminous materials are accepted on the test results of samples selected and tested by the Department or its authorized representative. Collect samples in accordance with Subsection
402.03.2 and tested using the applicable AASHTO method. The Project Manager may permit
using bituminous materials before the test results are available if the test results of material previously furnished by the refiner have consistently been satisfactory. The use of bituminous materials before receipt of the test results as permitted by the Project Manager does not waive the Department’s right to accept or reject materials under these specifications. Asphalt cement penetration is sampled and accepted in accordance with Subsections
402.03.2 and 402.03.5(B).
TABLE 702-1 BASIS FOR ACCEPTANCE OF BITUMINOUS MATERIALS Sample Tested Specification Limits1 Remarks Test Results Within Limits Test Results Outside Limits2 Original sample accept material test retained sample Retained samples may be tested by the Department at any time. Retained sample accept material accept material at reduced price or reject Notes:
1.See specification for bituminous materials.
2.Pay adjustments will be applied under QA. If test results of both the original and retained samples are not within the tolerance limits, the average of the two values will determine the basis for acceptance of the material. 702 – BITUMINOUS MATERIALS 2020 EDITION V5.1 702-2 Exception: If either of the two test values are outside the applicable ASTM Repeatability Range, then the test value numerically nearest the specification requirement will be used as the basis for acceptance. In the event a material fails more than one test requirement, that requirement with the greatest violation will determine the basis for acceptance. See Subsection
402.03 5(C)
for the method of calculating price reductions.
