Wisconsin WisDOT Standard Specifications (within FDM) — Section 325

Effective with the December 2018 Letting 133 2019 Standard Spec ifications Section 325 Pulverized and Re-laid Pavement

325.1Description

(1)This section describes full dept h in-place pulverizing of the existing asphaltic pavement along with a

portion of the underlying base and relaying the pulverized mate rial to construct a new base. 325.2 (Vacant)

325.3Construction

(1)Pulverize the full depth of the existing asphaltic pavement un til 97 percent or more will pass the 2-inch

sieve. Also pulverize the exis ting base to the depth the plans show and mix with the pulverized asphaltic pavement. Windrow mat erial as construction operations dictate.

(2)Immediately after pulverizing, r elay the material with a paver , grader, or both a paver and grader.

(3)If sufficient material is available at a given location, match the lines, grades, and cross slopes the

plans show. If there is insuffici ent material at a given locati on, shape the available material to create a smooth profile and cross slope for a good ride. Eliminate localized bumps, depressions, and ruts. Unless the engineer specifically directs, the contractor is not required to haul material from one location on the project to another.

(4)Immediately after relaying, compact the re-laid material first with either a rubber tired roller or vibratory

padfoot roller and second with a v ibratory steel roller. Add water, as required, both before and during compaction. Compact each layer to the extent required for stand ard compaction under 301.3 . Use compaction equipment as follows:

1.For a compacted lift of 6 inc hes or less, use equipment as specified in 301.3.1.

2.For a compacted lift from 6 to 8 inches, use a 12.5-ton or heavier vibratory padfoo t roller and an 8-ton or

heavier vibratory steel roller.

3.For a compacted lift greater than 8 inches, split into lifts less than 8 inches and use the equipment

specified for those lift thicknesses.

(5)Perform each day's pulverize and relay operations to avoid leaving abrupt longitudinal differences

between adjacent lanes. Repair surf ace damage caused by interve ning construction or public traffic immediately before paving as ne cessary to provide a good riding pavement.

325.4Measurement

(1)The department will measure Pulv erize and Relay by the square yard acceptably completed,

measured using the centerline length and the width from outside to outside of completed base, but limited to the width the plans show or the engineer directs.

325.5Payment

(1)The department will pay for the measured quantity at the contr act unit price under the following bid

item: ITEM NUMBER DESCRIPTION UNIT

325.0100 Pulverize and Relay SY

(2)Payment is full compensation for pulverizing, windrowing, rela ying, adding water, shaping, and

compacting. If the engineer requires hauling material from one location on the proj ect to another, the department will pay for that hauling as extra work.

(3)Payment also includes water fo r compaction and dust control ex cept, if the contrac t contains the Water

bid item, the department will pays eparately for compaction and dust control water under 624.5 .

Effective with the December 2018 Letting 134 2019 Standard Spec ifications Section 330 Milled and Re-laid Pavement

330.1Description

(1)This section describes partial depth in-place milling of the e xisting asphaltic pavement and relaying the

milled material to construct a new base. 330.2 (Vacant)

330.3Construction

(1)Mill the existing asphaltic pavement to the depth the plans show and until 100 percent will pass the 1

1/2-inch sieve. Windrow materia l as construction operations dic tate.

(2)Immediately after milling, relay the material with a paver, gr ader, or both a paver and grader.

(3)Match the lines, grades, and cr oss slopes the plans show. Elim inate localized bumps, depressions,

and ruts. Unless the engi neer specifically di rects, the contractor is not required to haul material from one location on the project to another.

(4)Immediately after relaying, compact the re-laid material first with either a rubber tired roller or vibratory

2.For a compacted lift from 6 to 8 inches, use a 12.5-ton or heavier vibratory padfoo t roller and an 8 ton or

heavier vibratory steel roller.

3.For a compacted lift greater than 8 inches, split into lifts less than 8 inches and use the equipment

specified for those lift thicknesses.

(5)Perform each day's mill and re lay operations to avoid leaving abrupt longitudinal differences between

adjacent lanes. Repair surface damage, caused by intervening co nstruction or public traffic, immediately before paving as ne cessary to provide a good riding pavement.

330.4Measurement

(1)The department will measure Mill and Relay by the square yard acceptably completed, measured

using the centerline length and the width from outside to outside of completed base, but limited to the width the plans show or the engineer directs.

330.5Payment

(1)The department will pay for the measured quantity at the contr act unit price under the following bid

item: ITEM NUMBER DESCRIPTION UNIT

330.0100 Mill and Relay SY

(2)Payment is full compensation fo r milling, windrowing, relaying , furnishing and adding water, shaping,

compacting, and removing and disposing of excess material. If t he engineer requires hauling material from one location on the project to another, the department wil l pay for that hauling as extra work.

(3)Payment also includes water fo r compaction and dust control ex cept, if the contrac t contains the Water

bid item, the department will pays eparately for compaction and dust control water under 624.5 .
