DESCRIPTION
410.01 Description
This work consists of constructing a Bituminous Plant -Mix Surface Course (Cold Mix), composed of aggregate and bituminous material, on a designated base in one or more layers and at the rate of application shown on the Plans or established by the Engineer. MATERIALS
410.02 Materials
Provide materials as specified in: Mineral Aggregate ................................ ................................ . 903.10 Emulsified Asphalt, Grade AE -3 ................................ ........... 904.03 410.03 349 The Engineer will accept mineral aggre gate for gradation in the stockpile at the paving plant site, and plant mixed material after being spread on the road. The Engineer may conditionally accept bituminous material at the source.
410.03 Composition of Mixtures
Combine the specified mineral aggregate and bituminous material in such proportions as to produce mixtures within the master composition limits specified in Table 410.03 -1. Table 410.03-1: Proportions of Total Mixture, Percent by Weight Material Components Percent by Weight Mineral Aggregate 93.0 – 95.0% Emulsified Asphalt 5.0 – 7.0% EQUIPMENT
410.04 Equipment
Provide equipment as specified in 407.04 with the following modifications:
1.Automatic screed control devices will not be required on the bituminous pavers.
2.Plant equipment required for heating or drying materials and for blending different size aggregates will not be required. CONSTRUCTION REQUIREMENTS
410.05 Limitations
Comply with the limita tions specified in 407.09.
410.06 Preparing Designated Surface
Prepare the designated surface upon which the material is to be placed as specified in 404.05. 410.07 350 410.07 Mixing Perform mixing as specified in 407.13. The Contractor may either stockpile the mix or haul it directly from the mixer to the road. If stockpiled, ensure that the material shows no damage from weather or signs of stripping during handling.
410.08 Spreading and Finishing
Perform spreading and finishing and spreading choker aggregate as specified in 407.14.
410.09 Compaction
Perform compaction operations as specified in 407.15.
410.10 Surface Requirements
Comply with the surface and testing requirements specified in 407.18 to ensure th at the deviation of the surface from the testing edge of the straightedge does not exceed ¼ inch.
