6.0 TEST METHODS FOR WATERBORNE TRAFFIC LINE PAINT

6.1 DRY-THROUGH (EARLY WASHOUT)

Draw down the paint on a glass panel to a wet film thickness of 15 mils.

Immediately place in a humidity chamber maintained at 70F ± 5F and 90% ± 5% relative humidity. Humidity outside of the chamber shall not exceed 50%.

Only two panels shall be placed in the chamber at one time. Rohm Haas 3427 paint formula will be run with each sample as a control. The control shall dry in 90 –100 minutes or the test shall be invalid. Begin testing the panels at 90 minutes and at 10-minute intervals thereafter until 130 minutes has elapsed.

(More frequent testing times allow the paint to prematurely cure and will give an erroneous result.) Test in accordance with ASTM D1640 except that the pressure exerted will be the minimum needed to maintain contact with the thumb and film.

6.2 STATIC HEAT STABILITY

Pour paint into a lined pint container to within 0.25 inches from the top, close the container, seal it with clips and tape, then place the container in an oven maintained at 140F 2°F for 7 days. Equilibrate the paint at standard conditions and mix thoroughly with gentle stirring for a minimum of 2 minutes but not more than 5 minutes. The paint shall not show signs of livering, hard settling, coagulating, lumps, or coarse particles. Then perform the consistency test according to ASTM D562 at 77F. The paint shall show no increase or decrease in viscosity greater than 7 KU over the original viscosity at 77F.

6.3 FREEZE-THAW

Test in accordance with ASTM D2243 for 3 freeze-thaw cycles. Equilibrate the paint at standard conditions and mix thoroughly with gentle stirring for a minimum of 2 minutes but not more than 5 minutes. The paint shall not show excessive signs of livering, hard settling, coagulating, lumps or coarse particles.

Then perform the consistency test in according to ASTM D562 at 77F. The paint shall show no increase or decrease in viscosity greater than 5 KU over the original viscosity at 77F.

6.4 COLOR AND APPEARANCE

Paint drawdowns shall be prepared according to ASTM D823. Colors shall not vary from the standards mentioned herein. Color determination shall be made without beads, at least 24 hours after application.

Color and appearance shall be evaluated using the following: Illuminant C, and standard observer angle 2 degrees. The geometry shall be 45/0 or 0/45.

Measurements shall be taken from samples applied to an opacity chart, e.g., Leneta Form 2A, at a wet film thickness of 15 mils ± 1 mil. The applied sample shall have been allowed to dry for at least 24 hours before measurements are taken. The evaluation shall be as follows:

The color of the dry paint film of the sample shall match the XYZ values provided, under the specified conditions.

For white material: Y > 90. For yellow material, the target values are: X = 63.59, Y = 57.46, Z = 7.60.

7 | P a g e

The colors shall match when compared instrumentally. Tolerances for Yellow are as follows.

X range 60 – 67 units, Y range 55 – 59 units, Z range 6.5 – 8.5 units.

The measurements shall be taken from a sample applied over the white portion of an opacity chart. The Administration will approve or disapprove any batch based on a laboratory visual evaluation for blemishes and irregularities in the test specimen (i.e. cracks, flaking, surface depressions, pooling, etc.) that would interfere with the measurement of color and appearance on the opacity chart.

The Administration will make the final decision.

The reflectance, without beads, and using CIE XYZ Yxy, shall be a minimum Y of 90% for white production batches; and a range of 55-59% for yellow production batches. The measurement shall be taken from a sample applied over the black portion of an opacity chart.

6.5 BLEEDING RATIO

Test in accordance with ASTM D868, except that the bleeding ratio is calculated by dividing the average reflectance of the paint applied to the asphalt-saturated felt by the average reflectance of the paint applied to the tape. Method of determining reflectance reading shall be the same as the method used to determine directional reflectance. (See Section 6.7) A 15 mil wet film thickness of paint shall be applied to the asphalt-saturated test panel

6.6 CONTRAST RATIO

Test in accordance with ASTM D2805, except that the drawdown shall be applied with a 5-mil bird bar to a hiding power chart and air-dried overnight.

The test film is prepared as detailed in ASTM D823.

6.7 DIRECTIONAL REFLECTANCE

Test in accordance with ASTM E1347, except using an instrument equal to Photovolt Model 577 with 45-degrees, 0-degree search unit and green filter standardized with a secondary standard of a porcelain-enameled metal plate.

The test film is prepared as in Section 6.6.

6.8 YELLOWNESS INDEX

Yellowness Index will be tested using a Photovolt Model 577 with 45-degrees, 0- degree search unit with amber, blue and green filters readings being taken on the white background. The test film is prepared as in ASTM D823 using a 6-mil wet film thickness of paint applied to a Hiding Power Chart and air-dried overnight. CIE Tristimulus values X, Y, Z, and the Yellowness Index are calculated as shown below:

X = (0.8 x (amber reading) + 1.8 x (blue reading)) / 100 Y = 1.0 x (green reading) / 100 Z = 1.18 x (blue reading) / 100 Yellowness Index = [1.25 x (X) – 1.038 x (Z)] / (Y)

8 | P a g e

6.9 SETTLING

Settling will be tested by filling a round-bottom centrifuge tube with the calculated weight of paint so that when it is centrifuged at the required revolutions per minute it will create 250 Pounds-force on the paint. The sample shall be revolved for two hours. The department will use a centrifuge tube capable of holding 150 grams of paint and it will be centrifuged at approximately 1820 revolutions per minute. The paint shall not show a clear separation at the top of the tube of more than 0.25 inches and the cake that forms in the bottom of the tube shall not be greater than 3.5 inches. The cake at the bottom of the tube shall be capable of being penetrated when probed with a stirring rod.

6.10 SKINNING

Fill a lined paint can 3/4 full with paint and seal tightly. Invert the can momentarily then turn it upright. Place the can in an area where the temperature is between 70F and 80F for 7 days. The sample shall not be agitated or disturbed until inspected. No evidence of a skin shall be present.

6.11 FLEXIBILITY

Test in accordance with ASTM D522 Test Method B, except that a 6 mil wet film thickness of paint is applied to a tin plate panel and baked for three hours at 220°F 2°F after air-drying overnight. After cooling the panel is bent 180 degrees over a 0.25 inch mandrel and examined without magnification. The paint shall show no evidence of cracking, flaking, or loss of adhesion.

6.12 CRACKING

The dry film shall show no cracks when examined after drying for 24 hours. The film shall be cast with a 15 mils wet film on 15 pounds asphalt saturated felt.

6.13 NO-TRACKING TIME

The paint shall be applied to smooth asphalt or concrete pavement at a wet film thickness of approximately 15 2 mil. Application of the glass beads shall be at a rate of 6-7 lbs/gal of paint. Dry pavement temperature may vary between 50°F and 122F. The relative humidity shall be a maximum of 85%. The no-tracking time shall be determined by a simulated passing maneuver made by a passenger car crossing over the paint line at a speed of approximately 40 mph. A line showing no visual pickup and redepositing of the materials onto the pavement surface, when viewed from a distance of 50 feet in the highway direction is considered as showing no pickup and conforming to the dry time requirements. Under special circumstances of weather and pavement conditions, the paint may be heat applied at a temperature not to exceed 95°F to achieve the specified dry time.

6.14 SCRUB RESISTANCE

Test in accordance with ASTM D 2486 with the following exceptions.

In Section 8.1, replace the 7.0 mil clearance applicator with an applicator that will provide a wet film of 15 mils.

9 | P a g e

Replace Section 8.5 with the following:

“Record the number of cycles to remove the paint film fully in one continuous 1/8 inch wide line across the 1/2-inch width of the shim. Stop the machine and wipe off the area to determine the end point”.

All bid samples will be tested using a GARDCO D10 Set Speed Linear Motion Test Machine. The test will be performed using a Nylon bristle brush in an aluminum block with a 5/4 pattern.
