(1)Select the rubberized membrane, primer, and mastic from the de partment's APL. Use membrane at

least 60 mil thick. 516.3 Construction 516.3.1 General

(1)Do not perform dampproofing and waterproofing in wet weather or if the air temperature or the

concrete temperature is below 45 F, unless the engineer specifi cally allows.

(2)Do not cure surfaces that require dampproofing or waterproofin g with membrane curing material.

(3)Cure the concrete and finish the concrete surface as specified for concrete surface finish in 502.3.7

before applying dampproofing or waterproofing.

(4)During primer application, ensur e the concrete surface is dry and thoroughly clean, free from

contaminants, dust, or ot her loose material.

(5)Apply at a material temperatur e that allows uniform application. If required, heat material uniformly in a

kettle with an armored thermometer. Do not heat asphalt above 3 50 F or coal-tar pitch above 250 F. 516.3.2 Dampproofing

(1)Under the Dampproofing bid item, provide a prime coat and a finish coat of asphalt, coal-tar pitch, or

emulsified asphalt.

(2)Apply a light coating of the primer to the concrete surface after preparation, cleaning, and drying.

Apply the primer to thoroughly and uniformly coat the concrete surface. Apply the finish coat after the prime coat cures but is still tacky to the touch.

(3)Apply asphalt, coal-tar pitch, or emulsified asphalt so that i t uniformly and completely covers the

primed surface. Use n o less than 4 1/2 gallo ns, for each 100 sq uare feet of surface, of asphalt, coal- tar pitch, or emulsified asphalt. 516.3.3 Rubberized Membrane

(1)Under the Rubberized Membrane Waterproofing bid item, provide a prime coat, one layer of a

preformed rubberized asphalt and plastic film membrane, and col d-applied rubberized asphalt mastic.

(2)Prime the concrete surfaces wi th the membrane manufacturer's p rimer, applied by brush or roller at

the rate of 250 to 350 square fee t per gallon. Let the primer dry one hour or until tack free. Re-prime primed surfaces not c overed within 36 hours. Do not prime dense surfaces like metal, but ensure it is clean, dry, and free of grease, oil, dust, or other contaminants.

(3)Apply a single layer of membrane to the accepted primed surfac e. Overlap 9 inches at membrane

joints and double cover intersections to eliminate butt joints in the membrane. Chamfer or round the exterior corners.

(4)Apply a double layer of membrane around drains, posts, bolts, or other protrusions and liberally coat

them with mastic next to seams a nd protrusions after applying t he membrane.

(5)Apply a trowelled bead of cold-applied rubberized asphalt mast ic to the perimeter of the membrane

placed in any day's operation and to all outside edges of membr ane after placing the membrane.

(6)Make a careful inspection of t he membrane and patch any ruptures, misaligned seams, or other

discontinuities with membrane and place any required backfill m aterial against the membrane. Backfill within 30 days of installation o r otherwise protect from ultra violet radiation.

Effective with the December 2018 Letting 289 2019 Standard Spec ifications 516.4 Measurement

(1)The department will measure Damp proofing by the square yard ac ceptably completed.

(2)The department will measure Rubberized Membrane Waterproofing by the square yard acceptably

completed, measured as the length of concrete joint sealed times the plan width of membrane with no additional allowance for overlap at joints and intersections.

516.5Payment

(1)The department will pay for measured quantities at the contrac t unit price under the following bid

items: ITEM NUMBER DESCRIPTION UNIT

516.0100 Dampproofing SY

516.0500 Rubberized Membrane Waterproofing SY

(2)Payment for Dampproofing and Rubberized Membrane Waterproofing is full compensation for heating

materials; for applying prime c oats, mastic, and asphalt, coal- tar pitch, or emulsified asphalt; and for placing preformed membrane.

Effective with the December 2018 Letting 290 2019 Standard Spec ifications Section 517 Paint and Painting

517.1Description

(1)This section describes furnis hing paint materials and applying paint to steel or ti mber structures,

including structural steel, misc ellaneous metal or lumber, or t imber parts of other structures. This work also includes, unless specified otherwise in the contract, prep aring surfaces for painting, applying paint, protecting and drying the paint coatings; protecting traffic and property upon and in the vicinity of the structure; and pr otecting of all portions of the structure against disfigurement by paint or paint materials.

(2)This section also describess hop cleaning; the furnishing and shop application of a complete epoxy

coating system on new structural steel; the field cleaning and repair of surfaces field welded or damaged in shipping, handling and er ecting the structural steel ; and providing a field-applied urethane top coat on exterior girders.

517.2Materials

517.2.1 General Requirements

(1)All coatings or paints shall c onform to the requirements speci fied for the type of coating or paint

named.

(2)Furnish factory mixed paint or field mix according to the manu facturer's directions and as the contract

directs.

(3)Ready-mixed paints shall not settle or cake in the container, but should break up readily with a paddle

to a smooth, uniform paint of good brushing consistency that dr ies without streaking, wrinkling, running, or sagging if painted on smooth, vertical surfaces. Pr ime and undercoats shall dry to a dull gloss, and finish coats to a full gloss. If required, colors and hiding powers shall equal those of samples the department furnished . Any proportions specified in formulae are by weight, unless indicated otherwise in the requirements for specific paint. 517.2.2 Containers

(1)Generally, paint shall arrive packaged in strong, tight, stand ard commercial, 5 US standard-gallon

capacity metal containers, except for the fractional parts of u nits. Package the fractional parts in one US standard-gallon capacity metal containers. If mechanical mea ns for mixing and stirring are provided at the job site or painting facility, then the contrac tor may furnish the paint in 30 gallon or other suitable size metal containers.

(2)Mark each container with the name and address of the manufactu rer, the type of paint contained, and

the date of manufacture. Use tight -fitting covers on the contai ners and arrange them so that the inspector may attach wire-lead seals.

(3)Except as specified above for mixing paint mechanically, mix paint on the job in c ontainers with not

more than 15 gallons capacity. 517.2.3 Inspection, Sampling, and Testing

(1)Paint sampling and inspection normally takes place at the poin t of manufacture; the department may

sample the paint at the fabricating shop or in the field. The engineer will obtain samples of paints purchased directly by the state, either for approval at their p oint of manufacture, or at their destination as indicated, either at the time c ontracts are awarded, or in t he invitation for bids.

(2)If inspecting paints at the poi nt of manufacture, the manufact urer shall furnish, if requested, any

formulae required to determine the ingredients before making th e paints. The manufacturer shall allow the inspector to check the make up and grinding of paint batches and shall allow test sampling of any or all batches. The manufacturer also shall furnish, if requested, any formulae required to determine specification conformance.

(3)Take representative samples of ready-mixed paints after thoroughly mixing the paints. Consider one

container chosen at random from each lot or batch for each coat , or if a batch or lot exceeds 500 gallons, one container for each 500 gallon increment or fractio n thereof, as repres entative. Take a one-pint sample from the represen tative container in the inspec tor’s presence. It is the contractor or manufacturer’s responsibility to ensure paint mixing occurs in a container that allows sampling of the paint it contains. Take field samples only from paint that is o n the job. Take samples in fabricating shops from containers of paint pro posed for the specific bid it em of work.

(4)Perform tests according to applicable standard methods of ASTM or AASHTO.

(5)The engineer may waive sampling a nd testing requirements for q uantities of 5 gallon or less of paint of

any single formulation required for each project, provided the paint purchased is from stock that demonstrated a satisfactory service record.
