Specifications include, but are not limited to: A. Description. Removing pavement will involve milling a 4” patch area and creating 4” vertical "butt" joints on all sides of the patch in order to match existing pavement. Should topographic or other physical constraints prevent a milling machine from making a satisfactory straight line, vertical "butt" joint, the contractor shall provide all labor and equipment necessary to complete the joint by other means. B. Method of Measurement. Milling shall be measured by the square yard of pavement surface ground. Widths of grinding greater than designated by the County shall be at the contractor's expense. A. Description. Materials covered under this provision shall conform to the State of Wisconsin, Department of Transportation's specifications for each “Type” mix. The contractor will be responsible for providing mix design(s) and for testing required to insure uniformity of mix and adequacy of compaction. A mix design must be submitted to the County for approval a minimum of 2 weeks prior to the start of paving. In no case will paving be allowed to begin until the County is in receipt of said mix design(s). Section 460.2.1 Replace the entire text with the following: (1) Furnish a homogeneous mixture of coarse aggregate, fine aggregate, mineral filler if required, SMA stabilizer if required, recycled material if used, warm mix asphalt additive or process if used, and asphaltic material. Design mixtures conforming to table 460-1 and table 460-2 to 4.0% air voids to establish the aggregate structure. HMA Pavement is per the WisDOT 2019 HMA specification using 3% air voids by the addition of liquid asphalt to achieve the required air voids. (2) Determine the target JMF asphalt binder content for production from the mix design data corresponding to 3.0% air voids (97% Gmm) target at the design the number of gyrations (Ndes). Add liquid asphalt to achieve the required air voids at Ndes. (3) For SMA, determine the target JMF asphalt binder content for production from the mix design data corresponding to 4.0% air voids (96% Gmm) target at Ndes.
