ASTM D517-23 PDF

Overview

ASTM D517-23 - Standard Specification for Asphalt Plank is an internationally recognized standard developed by ASTM International, detailing requirements for asphalt plank utilized in bridge deck waterproofing and industrial flooring applications. This specification outlines material composition, classification, manufacturing guidelines, and essential physical properties, ensuring consistent quality and reliable performance. ASTM D517-23 plays a critical role in infrastructure durability, primarily focusing on applications where long-term service and protection against environmental factors are essential.

Key Topics

• Classification: Asphalt planks are classified into three types based on their application and construction:

  • Type Ia: Plain, butt-edge plank for industrial floors.
  • Type Ib: Plain, butt-edge plank for use as a protection layer in railroad bridge deck waterproofing.
  • Type II: Ship-lap edge plank designed for railroad bridge waterproofing protection.

• Material Composition: Asphalt planks are manufactured from a uniformly dense mixture of asphalt, fibers (natural or synthetic, excluding asbestos), modifiers, and mineral filler (such as slate, limestone, or silica).

• Physical Requirements: The specification sets stringent criteria regarding:

  • Absorption: Maximum 1.0% by weight, measured to verify low porosity.
  • Brittleness: Test ensures resistance to cracking in cold conditions.
  • Hardness: Performance under specified temperatures and loads to guarantee structural integrity during use.
  • Dimensions and Mass: Strict tolerances ensure planks fit design requirements and maintain consistent coverage.

• Workmanship & Appearance: Planks must be free from visible defects, have straight edges, and possess square corners for proper installation and functionality.

Applications

• Bridge Deck Waterproofing: Asphalt plank is widely used as a protection course in waterproofing systems for bridge decks, providing a durable barrier against water infiltration and extending the lifespan of the structure.

• Railroad Infrastructure: Both Type Ib and Type II planks are specifically designed to safeguard waterproofing membranes on railroad bridges, enhancing resilience against vibrations and heavy loads.

• Industrial Flooring: Type Ia planks serve as robust industrial flooring solutions in facilities subjected to high traffic, heavy equipment, and fluctuating environmental conditions.

By adhering to ASTM D517-23, project stakeholders-including engineers, contractors, and facility managers-ensure that asphalt plank materials meet uniform standards, optimizing performance and reducing the risk of premature failure.

Related Standards

Each of these standards complements ASTM D517-23 by addressing adjacent material requirements and installation practices for paving, flooring, or bridge construction projects.

Practical Value

Using asphalt plank conforming to ASTM D517-23 guarantees:

• Consistent protection against water ingress and mechanical stress
• Extended service life for bridges and industrial floors
• Reliable performance under a variety of temperature and load conditions
• Ease of installation and reduced maintenance through strict dimensional controls

This standard is essential for professionals seeking durable, high-performance solutions in structural waterproofing and heavy-duty flooring, ensuring compliance with international best practices.
