SPECIAL PROVISIONS - SP2016 BOOK Last Revision by CO Special Provisions: 2/08/17 Created August 20, 2015 Page 27 SP 0202-101 Table 2360-8 Requirements for Ratio of Added New Asphalt Binder to Total Asphalt Binder' min%: PG 58X3-34 Wear & Non -Wear 80 80 80 ' The ratio of added new asphalt binder to total asphalt binder is calculated as (added binder/total binder) x 100 2 The Contractor can elect to use a blending chart to verify compliance with the specified binder grade. The Department may take production samples to ensure the asphalt binder material meets the requirements. The blending chart is on the Bituminous Office Website. 3 X=S,H,V,E S-31.3 Mix Designation Numbers for the bituminous mixtures on this Project are as follows: Type SP 9.5 Wearing Course SPWEA340B Type SP 12.5 Non -Wearing Course SPNWB340B S-31.4 Asphalt binder meeting AASHTO M332 (MSCR) is required. See Section S-3151 (BITUMINOUS MATERIAL (MSCR)) of these Special Provisions. S-31.5 The sentence "In addition to the list the above the pavement surface must meet requirements of 2399 (Pavement Surface Smoothness) requirements." is deleted from MnDOT 2360.3.E Surface Requirements. The requirements of MnDOT 2360.3.E Surface Requirements will apply. S-31.6 The first paragraph of MnDOT 2360.2.G.4.b Sampling and Testing is revised as shown below: Take QC samples at random tonnage or locations, quartered from a larger sample of mixture. Sample randomly and in accordance with the Schedule of Materials Control. Determine random numbers and tonnage or locations using the Bituminous Manual; Section 5-693.7 Table A or ASTM D 3665, Section 5, or, an Engineer approved alternate method of random number generation.

Sample mixture from behind the paver. Sampling from the truck box at the plant site is not allowed unless approved by the Engineer. In addition to the OC sample, the Contractor will also bring an additional split of the mixture sample to the plant site and store for the Department for 10 calendar days. The procedure for truck box sampling is on the Bituminous Office website. The Contractor will obtain at least a 130 pound [60 kg] sample Split the sample in the presence of the Inspector. The Inspector will retain possession of the Agency portion of each split sample and randomly submit a minimum of one sample, on a daily basis, to the District Laboratory for Verification testing (see 2360.2.G.3). Store compacted mixture specimens and loose mixture companion samples for 10 calendar days. Label these split companion samples with companion numbers. S-31.7 The first paragraph of MnDOT 2360.3.D.1 is hereby deleted and replaced with the following: D.1 Maximum Density Compact the pavement to at least the minimum required maximum density values in accordance with Table 2360-19, "Required Minimum Lot Density (Mat)". S-31.8 MnDOT Table 2360-20 Longitudinal Joint Density Requirement is hereby deleted. S-31.9 MnDOT 2360.3.D.1.h Mat Density Cores is hereby deleted and replaced with the following: D.1.h Mat Density Cores
