- 352 - SECTION 511 -- SALVAGING AND STOCKPILING BITUMINOUS MATERIAL
511.01 Description
1.This work will consist of salv aging, hauling, and stockpiling existing bituminous surfacing for the Department to locations shown in the contract.
2.The bituminous surface shall be removed by cold milling. If the road is closed to all but local traffic, the Contractor may use other approved methods, except heating, to remove and pulverize the bituminous material.
511.02 Material Requirements
1.The salvaged material shall be pu lverized until all of the material will pass a 2 inch (50 mm) sieve. The Contractor shall avoid including any of the underlying material with the salvaged bituminous surfacing material.
511.03 Equipment
Cold milling equipment shall c onform to the requirements of Subsection 510.03.
511.04 Construction Methods
1.Cold milling shall be performed in accordance with Section 510.
2.a. The Engineer will locate each stockpile. b. The Contractor shall prepare stockpile sites by removing all vegetation on the portion of the site on which the material will actually be placed. The stockpile area shall be graded so that water will drain away from the stockpiled material. Unsurfaced areas upon which material is stockpiled shall be smoothed and rolled so that the salvaged material may later be removed with a minimum of loss.
c.The maximum height of stockp iles is 10 feet (3 m). Equipment shall not be driven over the stockpiled material.
511.05 Method of Measurement
1.The work of salvaging and stockpiling bituminous material will be measured for payment by the ton (Meg agram) of material placed into stockpile sites.
511.06 Basis of Payment
1.P a y I t e m P a y U n i t Salvaging and Stockpiling Bituminous Material Ton (Tn) [Megagram (Mg)]
2.Cold milling will be paid for under Section 510.
3.Payment is full compensation for all work described in this Section. - 353 - SECTION 512 -- BITUMINOUS SURFACE COURSE
512.01 Description

4.The Contractor shall compact the bituminous material with three complete coverages of a roller or other approved compaction equipment.
512.04 Method of Measurement
1.The bituminous surface course will be measured for payment by the square yard (square meter).
512.05 Basis of Payment
1.P a y I t e m P a y U n i t Bituminous Surface Course Square Yard (SY) [Square Meter (m 2)]
