NEW YORK STATE DEPARTMENT OF TRANSPORTATION Sections 200 - 599 STANDARD SPECIFICATIONS (USC) January 1, 202 4 Volume 2 578-1.03 Placement Methods.
A.Method 1 - Separate Placement. Place Class D slab reconstruction concrete and Class E overlay concrete separately.
B.Method 2 - Integral Placement (Optional). When 100% of the top mat of bar reinforcement is exposed or when all of the following conditions are satisfied, Class E overlay concrete and Class E slab reconstruction concrete may be placed in a single lift.
1.The area of the exposed top mat of bar reinforcement is 5% or less of the placement area, per span.
2.No individual area of the exposed top mat of bar reinforcement exceeds 25 sf .
3.No dimension of any area of the exposed top mat of bar reinforcement exceeds 6 feet .

578-4 METHOD OF MEASUREMENT. For placements with 100% exposure of the top mat of bar
reinforcement, the number of square feet of slab reconstruction concrete will be equal to the number of square feet of overlay concrete. For placements with less than 100% exposure of the top mat of bar reinforcement, measure slab reconstruction concrete prior to overlay concrete placement.
A.Method 1 - Separate Placement. Measure slab reconstruction concrete as the number of square feet of Class D slab reconstruction concrete placed. Measure overlay concrete as the number of square feet of plan area of Class E overlay concrete placed.

SECTION 579 - STRUCTURAL SLAB RECONSTRUCTION PREPARATION
579-1 DESCRIPTION. The work shall consist of initially preparing an existing structural slab for
reconstruction. Generally, this work shall entail the removal of concrete to the depths, and at the locations, required by the contract documents.
579-1.01 Structural Slab Scarification
A.This work shall consist of removing the top surface of structural slab concrete. Removal shall be done by scarification to the following limits, unless a greater depth is indicated on the plans:
1.Minimum of 1/4 inch
2.Maximum of 1/2 inch
B.After scarification, if a structural slab survey is required, the surface to be surveyed shall be cleaned sufficiently to allow the survey to be taken. The Engineer will determine if the surface is cleaned sufficiently to allow performance of the neces sary delamination and potential survey tests.
C.All removed materials shall be transported from the work site and disposed of or disposed of in an area on the job site approved by the Engineer.
579-1.02 Exposure of Reinforcing Bars
A.Definitions
1.Bar Mat. That combination of transverse and longitudinal reinforcing steel placed with the structural slab to absorb stresses. Structural slabs generally contain two bar mats; an upper mat and a lower mat.
2.Upper Mat. That bar mat closest to the existing top surface of the structural slab. Only the upper mat is relevant to this work, except in localized areas.
3.Localized Area. An area where full depth removal and subsequent patching will be done as part of this work. For the work of this section a localized area shall not exceed 25 sf . The sum of
