SPECIAL PROVISIONS - SP20I6 BOOK Last Revision by CO Special Provisions: 2/08/17 Created August 20, 2015 Page 28 SP 0202-101 Obtain four cores in each lot. Take two cores from random locations as directed by the Engineer. Take the third and fourth cores, the companion cores, within 1 foot [0.3 m] longitudinally from the first two cores. Submit the companion cores to the Engineer immediately after coring and sawing. If the random core location falls on an unsupported joint, at the time of compaction, (the edge of the mat being placed does not butt up against another mat, pavement surface, etc.) cut the core with the outer edge of the core barrel 1 foot [0.3 meters] away (laterally) from the edge of the top of the mat (joint). If the random core location falls on a confined joint (edge of the mat being placed butts up against another mat, pavement surface, curb and gutter, or fixed face), cut with the outer edge of the core barrel 6 inches ± 0.5 inch [150 mm ± 12.5 mm] from the edge of the top of the mat (ex. center of 4 inch [100 mm] core barrel 8 ± 0.5 inches [200 mm f 12.5 mm] from the edge of the top of the mat). Cores will not be taken within 1 foot [300 mm] of any unsupported edge. The Contractor is responsible for maintaining traffic, coring, patching the core holes, and sawing the cores to the paved lift thickness before density testing. The Engineer may require additional density lots to isolate areas affected by equipment malfunction, heavy rain, or other factors affecting normal compaction operations. S-31.10 following: MnDOT 2360.3.D,1.j Companion Core Testing is hereby deleted and replaced with the The Department will select at least one of the two companion cores per lot to test for verification. S-31.11 MnDOT 2360.3.D,1.n Longitudinal Joint Density is hereby deleted. S-31.12 MnDOT 2360.3.D.1.p Shoulders is hereby deleted. S-31.13 MnDOT Table 2360-24 Payment Schedule for Longitudinal Joint Density (SP Non -Wear and SP Shoulders, 4% Void) is hereby deleted. S-31.14 MnDOT Table 2360-25 Payment Schedule for Longitudinal Joint Density (SP Non -wear and SP Shoulders, 3% Void) is hereby deleted. S-31.15 MnDOT 2360.3.D.1.r Pay Factor Determination is hereby deleted. S-32 (2461) STRUCTURAL CONCRETE REVISED 02/07/17 MnDOT 2461 is hereby modified as follows: S-32.1 MnDOT 2461.2.A.5 shall be added: A.5 Ternary Mixes Ternary mixes are defined as portland cement or Type IL and two other supplementary cementitious materials, or blended cement and one other supplementary cementitious material with a maximum replacement of 40% by weight. S-32.2 MnDOT 2461.2.B shall be deleted and replaced with the following: B Aggregates Provide aggregates from sources listed on the MnDOT Concrete Aggregate Properties list. B.1 Fine Aggregate 3126 B.2 Intermediate Aggregate 3131 B.3 Coarse Aggregate 3137
