d.White Pigmented Curing Compound- Wax Base ................................................................................. ASTM C309, Type 2, Class A*
e.White Polyethylene Sheeting (film) for Curing Concrete ................................ ................................................................. ASTM C171 * Except: The loss of water from the surface in the water retention test shall not exceed 0.45 kg/m2 (1.50 oz/ft2) in 72 hours. Curing compounds shall be tested and certified by a reputable testing laboratory recognized by the Department. Use curing compounds listed in the QPL.
702.03.02 Air -Entraining Admixtures. Air-entraining admixtures shall conform to ASTM C260.
702.03.03 Admixtures Other Than Air -Entraining. Admixtures shall conform to ASTM C494. The admixtures
may be tested by Test Method No. CALIF. 530.
702.03.04 Bridge Deck Curing Compound. Bridge deck curing compound shall be a white pigmented curing
compound conforming to ASTM C309, Type 2, Class B. The resin type shall be poly -alpha- methylstyrene and the loss of water from the surface in the water retention test shall not exceed 0.15 kg/m2 (0.50 oz/ft2) in 24 hours nor more than 0.45 kg/m2 (1.50 oz/ft2) in 72 hours.
702.03.05 Pozzolans. Pozzolanic admixtures shall be Class C, Class F, or Class N conforming to ASTM C618,
except the loss on ignition shall not exceed 5%. Use pozzolans listed in the QPL. The laboratory furnishing test data must be inspected by the Cement and Concrete Reference Laboratory (CCRL) of the National Institute of Standards and Technology, Gaithersburg, Maryland. In addition, the laboratory must authorize reports of said inspectio ns to be sent to the Department’s Materials Division for review. If said inspection reports indicate that procedures or equipment used in the testing of pozzolan are substandard, test data from that laboratory will not be accepted. A Certificate of Compl iance from the supplier shall accompany each shipment of pozzolan.
702.03.06 Slag Cement and Silica Fume. Slag cement shall be Grade 120 and conform to ASTM C989. A
Certificate of Compliance from the supplier shall accompany each shipment of slag cement. Provide samples upon request. Silica fume shall conform to ASTM C1240. A Certificate of Compliance from t he supplier shall accompany each shipment of silica fume. SECTION 703 BITUMINOUS MATERIALS SCOPE
703.01.01 Materials Covered. This specification covers the quality of asphalt cement, cutback asphalt , and
emulsified asphalt. REQUIREMENTS
703.02.01 Demerit Schedule. Bituminous material failing the requirements of the tests hereinafter prescribed
shall be subject to the provisions of Subsection 109.02. Bituminous materials that cannot be tested by any of the specified test procedures due to the inherent nature of the material will be assessed 21 demerits. For asphalt cements, demerits will be assessed on a prorated basis on the difference between the LIMIT WITH TOLERANCE and the REJECTION LIMIT. For cutback asphalts and emulsified asphalts , demerits will be assessed for each increment of noncompliance. Demerit values will be rounded down to the nearest whole demerit.
703.02.02 Contractor’s Responsibility . When shipment of materials arrive on the project after normal
working hours, give notice sufficiently in advance to allow arrangements for an inspector to be present when the material is sampled. PHYSICAL PROPERTIES AND TESTS
703.03.01 Bill of Lading and Certificate of Compliance. A bill of lading and certificate of compliance shall
be submitted for every load of bituminous material. The bill of lading shall include the following data:
1.Date of shipment and shipping point.
2.Car initials and number of truck transport delivery ticket number.
3.Destination and consignee.
4.State contract number (or State purchase order number, if applicable).
5.Type , grade, quantity, and temperature of material loaded.
6.Signature of shipper or authorized representative.
703.03.02 Asphalt Cements. Prepare asphalt cement by the distillation of crude petroleum. Provide
homogenous asphalt, free from water, and non- foaming when heated to 175 ° C (347 ° F). Asphalt cements submitted for mix designs shall meet the specification requirements, without tolerances. The tolerance applies to production samples only. Asphalt cements shall conform to the requirements herein.
