AASHTO TP 103

Description / Abstract: This method of test covers the specimen fabrication, testing protocols, and laboratory-accelerated weathering of detectable warning systems for the purposes of evaluating durability. This method of test covers the following categories:

Non-Destructive Evaluation Tests:

• Visual and Microscopic Evaluation (Section 6)

• Dome Shape and Geometry Measurement (Section 7)

• Slip Resistance Measurement (Section 8)

• Color Measurement (Section 9)

Destructive Evaluation Tests:

• Resistance to Impact from Falling Tup (Section 10)

• Resistant to Impact from Simulated Snowplow Blade (Cold Exposure) (Section 11)

• Wear Resistance (Section 12)

• Coating and Single Dome Bond (Systems with Coatings or Surface-Applied Single Domes) (Section 13)

Laboratory-Accelerated Weathering—Exposure Regime (Hot and Cold Exposure Categories):

• High Temperature Thermal Cycling (Section 14)

• Abrasion Exposure (Section 15)

• Freeze–Thaw Durability (Cold Exposure Applications only) (Section 16) • Ultraviolet Light Exposure (Section 17)
