Overview

ASTM D8012-18, titled Standard Practice for Reclamation of Scrap and Waste Asphalt Shingles to Produce Reclaimed Asphalt Shingles (RAS) for Use in Transportation Applications, establishes a systematic approach for recovering and processing both manufacturing scrap and tear-off roofing asphalt shingles. The resulting reclaimed asphalt shingles (RAS) are suitable for use in various transportation-related applications, most notably in asphalt paving and as granular fill.

This standard provides essential guidance for ensuring material quality, operator competence, and facility qualifications. It outlines sourcing, inspection, sampling, testing, and stockpiling requirements, creating a baseline framework that supports both quality assurance and environmental stewardship in asphalt recycling efforts.

Key Topics

• Material Quality Requirements

  • Only asphalt shingles are allowed; other roofing materials are excluded except for incidental contamination.
  • Asbestos inspection and testing are required for each incoming load.
  • Processed RAS must meet gradation, cleanliness, and moisture content standards.

• Operator and Facility Qualifications

  • Operators must adhere to all applicable local, state, and federal regulations regarding waste management, health, and environmental protections.
  • Facilities need documented quality management systems and procedures for sampling and testing.
  • Certification forms are required to verify compliance for operations, incoming material, and outgoing RAS.

• Inspection and Testing Procedures

  • Mandatory asbestos testing using recognized microscopy methods.
  • Material gradation must meet specified sieve criteria for size reduction.
  • Extraneous materials such as metals, glass, rubber, and wood must be minimized according to set limits.
  • Moisture content must not exceed prescribed thresholds.

Applications

ASTM D8012-18 enables the responsible reclamation of asphalt shingles, supporting sustainability initiatives and optimizing resource utilization in transportation projects. Its primary applications include:

• Asphalt Paving Materials

  • RAS can be incorporated into the production of hot mix asphalt (HMA) for roadways, reducing the demand for virgin resources and lowering project costs.
  • Consistent quality management ensures reliability and performance of recycled asphalt materials.

• Unbound Materials for Road Construction

  • RAS is increasingly used as a granular fill, either alone or in combination with other materials, for applications such as base courses and embankments.
  • This practice fosters diversification of end-use possibilities and conserves landfill space.

• Environmental Compliance

  • Clear requirements regarding asbestos and extraneous waste safeguard public health and align with regulatory mandates for environmentally sound recycling practices.

Related Standards

ASTM D8012-18 references several standards fundamental to the reclamation and testing process, including:

• ASTM C136 - Test Method for Sieve Analysis of Fine and Coarse Aggregates
• ASTM D75/D75M - Practice for Sampling Aggregates
• ASTM D2216 - Test Methods for Laboratory Determination of Water (Moisture) Content of Soil and Rock by Mass
• ASTM E11 - Specification for Woven Wire Test Sieve Cloth and Test Sieves
• EPA 600-R-93-116 - Polarized Light Microscopy: Method for the Determination of Asbestos in Bulk Building Materials

Adhering to these referenced standards ensures the accuracy and reliability of material characterization, sampling, and safety protocols in RAS production.
