ASTM D5360/D5360M-23

Overview

ASTM D5360/D5360M-23: Standard Practice for Design and Construction of Asphalt Surface Treatments provides standardized guidance for the design and construction of bituminous (asphalt) surface treatments. Developed by ASTM International, this practice serves as a guide, not a specification, allowing adaptation to specific project and user requirements. Asphalt surface treatments, such as chip seals and seal coats, are widely used to maintain and extend the service life of pavements, offering enhanced durability, skid resistance, and weather protection.

This standard addresses both SI units and inch-pound units individually and highlights the importance of adhering to appropriate safety, health, and environmental protocols prior to application. It is intended for use by civil engineers, highway agencies, contractors, and infrastructure owners seeking consistent approaches to asphalt surface treatment projects.

Key Topics

• Scope and Applicability

  • Establishes best practices rather than mandatory requirements
  • Covers both single and multiple surface treatments
  • Applicable to roads, bridges, and general paving

• Material Selection

  • Bituminous materials: asphalt binder, emulsified asphalt, cutback asphalt, and road tar
  • Aggregates: size, cleanliness, and proper shape (preferably cubical)
  • Emphasizes matching material choice to climate, traffic, and job requirements

• Construction Procedures

  • Surface preparation: patching, cleaning, and ensuring a dry, debris-free base
  • Application of bituminous material and aggregate: specified rates, calibration, and timing
  • Rolling and compaction: techniques for embedding aggregate into the asphalt layer

• Safety and Environmental Considerations

  • Guidance on temperature thresholds and weather limitations
  • Precautions to ensure safe and environmentally responsible application

• Quality Assurance

  • Sampling and testing protocols for materials and finished work to ensure conformance

Applications

Asphalt surface treatments following ASTM D5360/D5360M-23 are widely applied for:

• Extending the service life of existing pavements by sealing cracks and preventing water intrusion
• Improving surface texture and skid resistance on both urban and rural roadways
• Providing cost-effective preventive maintenance for municipal streets and parking lots
• Treating bridge decks and other transportation infrastructure subjected to weathering
• Reducing maintenance costs by delaying more extensive pavement rehabilitation

Facilities management teams, municipal authorities, and transportation agencies benefit from utilizing this practice to optimize road safety, minimize disruption, and manage lifecycle pavement costs.
