Specifications include, but are not limited to: HYDRATED LIME SLURRY FOR ASPHALT MIXTURES: The Contractor will have the option of using Hydrated Lime Slurry For Asphalt Mixtures or Hydrated Lime For Asphalt Mixtures. Hydrated lime slurry will be added to all aggregates (at the Contractor’s option, limestone may be excluded) used for asphalt mixtures except Asphaltic Concrete used for Temporary Surfacing, and Asphaltic Concrete Type SPS and SPL. Hydrated lime slurry will be added to aggregates whether it is used directly into the mix or stockpiled for marinating purposes. The application of hydrated lime slurry to the aggregates along with equipment calibration and procedures shall be documented and approved in the Contractor's Quality Control (QC) Plan.; The lime shall meet the chemical and physical properties defined in AASHTO M 303 for Type I - High calcium-hydrated lime, or meet the requirements of ASTM 1097 for Type S Hydrated Lime.; The dry hydrated lime being used, whether for mix design or plant mix production, shall be stored in an enclosed container and must be used within 90 days. Stockpiles marinating shall also be used within 90 days. Hydrated lime (dry or slurry) that is stored over 90 days in a protected storage silo or slurry tank may be submitted for chemical analysis to verify that it meets the specification for use in the mix.; Hydrated Lime shall be added at a rate of 1.25 percent by weight of virgin aggregate, including the weight of the limestone.; HYDRATED LIME FOR ASPHALT MIXTURES: Hydrated lime will be added to all aggregates (at the Contractor’s option, limestone may be excluded) used for asphalt mixtures except Asphaltic Concrete used for Temporary Surfacing, and Asphaltic Concrete Type SPS, and SPL. Hydrated lime will be added to pre-moistened aggregates whether it is used directly into the mix or stockpiled for marinating purposes. The application of moisture and hydrated lime to the aggregates, along with equipment calibration and procedures to prevent any "dusting", shall be documented and approved in the Contractor's Quality Control (QC) Plan.; The lime shall meet the chemical and physical properties defined in AASHTO M 303 for Type I - High calcium-hydrated lime, or meet the requirements of ASTM 1097 for Type S Hydrated Lime.; The hydrated lime being used, whether for mix design or plant mix production, shall be stored in an enclosed container and must be used within 90 days. Stockpiles marinating shall also be used within 90 days. Lime that is stored over 90 days in a protected storage silo environment may be submitted for chemical analysis to verify that it meets the specification for use in the mix. ; Prior to the addition of hydrated lime, the aggregates shall have a minimum moisture content of 3% by weight of aggregate. The surface of the aggregate shall be uniformly dampened by water.; If additional moisture is required, it shall be added at the entry end of an enclosed pug mill mixer and prior to the addition of hydrated lime.; Hydrated Lime shall be added at a rate of 1.25 percent by weight of virgin aggregate, including the weight of the limestone.; ACRYLIC RESIN WATERBORNE LEAD-FREE TRAFFIC PAINT: 1. Condition in Container – The paint shall be finely ground; shall not show excessive settling; shall show no gelling, curdling, livering, caking, lumps, skins, or color separation and shall be easily dispersed with a hand paddle to a smooth, homogeneous state. After storage for periods up to 6 months from the date of packaging, the pigment shall be readily dispersed, and the consistency of the paint shall not have changed more than 5 KU (Krebs Units) from that of the freshly delivered paint. ; 2. Fineness of Grind – The traffic paint shall have a grind of not less than 3 on the Hegman Scale when tested in accordance with ASTM D 1210. ; 3. Color - For white traffic paint, the color after drying shall be a flat white, free from tint, furnishing good opacity and visibility under both daylight and artificial light. For yellow, the color shall closely match Color 33538 of Federal Standard 595b and shall be ± 6% from the PR #1 chart central color when read over the black portion of a Leneta black and white paper chart. Measurements shall be performed using a color spectrophotometer with a 45°/0° circumferential viewing geometry, illuminate “C”, and an observer of 2°. ; 4. Reflectance - The daylight directional reflectance (Y) of the white traffic paint shall not be less than 83. The daylight directional reflectance (Y) for the yellow traffic paint shall not be less than 50. The paint shall be applied to a Leneta black and white paper chart at a wet film thickness of 15 mils. After drying 24 hours, the reflectance of the traffic paint shall be measured over the black portion of the chart using a Hunter Lab color spectrometer or equal. (ASTM E 1347) ; 5. Contrast Ratio – The minimum contrast ratio for both white and yellow traffic paint shall be 0.96. The paint shall be applied on a Leneta black and white paper chart at a wet film thickness of 15 mils and dried for at least twenty-four hours. Using a color spectrometer, the Reflectance (Y) values of the paint shall be obtained using a 45° viewing angle, a 2° observation angle and illuminate “C”. Contrast Ratio is the ratio of the reflectance on a black square to that of an identical film on a white square.
