Astm D6307 Pdf !link! May 2026
ASTM D6307 outlines the ignition method for determining asphalt binder content in mixtures by burning samples at approximately 540°C, providing a solvent-free alternative for quality control. The procedure requires an ignition furnace, sample baskets, and calculates the corrected binder content based on weight loss. For the full standard, purchase the document from ASTM International.
ASTM D6307 is the standard test method for determining the asphalt binder content of hot-mix asphalt (HMA) mixtures using the ignition method
. This process involves heating a sample in an ignition furnace to burn off the asphalt cement, allowing technicians to calculate the binder percentage by comparing the sample's weight before and after ignition. ASTM International Core Objectives and Scope
: It is used for quantitative determination of asphalt content in paving mixtures and pavement samples for quality control and specification acceptance. Eco-Friendly Alternative : Unlike older methods like ASTM D2172, the ignition method does not require solvents , making it safer and more environmentally friendly. Secondary Use
: The aggregate remains left after the test can be used for sieve analysis to check gradation, though some particle degradation may occur due to the high heat. ASTM International The Two Standard Methods
The standard typically describes two primary procedures for conducting the test:
: Uses a furnace with an internal automatic balance that continuously monitors weight loss and automatically calculates the asphalt content percentage.
: Involves a furnace without an internal balance. The operator must manually remove the sample at specific intervals to weigh it until a constant mass is achieved. astm d6307 pdf

ASTM D6307 is the standard test method for determining the asphalt binder content of hot-mix asphalt (HMA) by burning it off in a furnace at approximately 540°C. The procedure provides a safe, solvent-free alternative for quality control and allows for subsequent sieve analysis on the remaining aggregate. Purchase the official standard at ASTM International
الإدارة العامة لرفع كفاءة المشاريع Asphalt Content of Asphalt Mixture by Ignition Method1
The ASTM D6307 standard specifies the test method for determining the asphalt content of hot-mix asphalt (HMA) mixtures using the ignition method. This process is a common alternative to solvent extraction methods, which are often more hazardous and time-consuming. Key Features of ASTM D6307
Quantitative Determination: Provides a precise measurement of the amount of asphalt binder in a mix by burning it off in a furnace at high temperatures (typically around
Correction Factors: Requires the determination of an aggregate correction factor to account for any mass loss in the minerals during the ignition process, ensuring the final binder calculation is accurate.
Automated Monitoring: Most modern furnaces compliant with this standard feature internal scales that monitor the mass loss in real-time, automatically stopping the test when the weight stabilizes. ASTM D6307 outlines the ignition method for determining
Sample Integrity: Once the asphalt is burned off, the remaining heated aggregate can often be used for sieve analysis (ASTM C136) to check the gradation of the mix.
Safety and Environment: Eliminates the need for chlorinated solvents like trichloroethylene, making it a "greener" and safer laboratory procedure for technicians.
Standardized Equipment: Outlines specific requirements for the ignition furnace, including ventilation systems to safely exhaust combustion gases and internal weighing systems. Typical Test Procedure Preparation: Dry the HMA sample to a constant mass.
Ignition: Place the sample in the furnace. The binder is ignited and burned away.
Calculation: The asphalt content is calculated as the difference between the initial mass and the final mass of the aggregate, adjusted by the specific correction factor for those materials. AI responses may include mistakes. Learn more
ASTM D6307-19 defines the standard ignition method for determining asphalt binder content in hot-mix asphalt by heating samples to approximately 540°C to measure weight loss. The standard covers both automatic furnace procedures and manual, external weighing methods, while requiring a calibration factor to account for aggregate degradation.

Understanding ASTM D6307: A Comprehensive Guide to the Standard Test Method for Hydrocarbon Traces in Propylene Concentrates
The American Society for Testing and Materials (ASTM) is a globally recognized leader in the development and delivery of voluntary consensus standards. Among its extensive catalog of standards, ASTM D6307 stands out as a crucial document for the petrochemical industry. Specifically, this standard test method, titled "Standard Test Method for Hydrocarbon Traces in Propylene Concentrates," plays a pivotal role in ensuring the quality and purity of propylene concentrates. This article provides an in-depth look at ASTM D6307, exploring its significance, the methodology it entails, and the importance of accessing the standard in PDF format.
Test Method Overview
The test involves comparing the microbial growth on a treated (test) sample, which contains the antimicrobial agent, to an untreated (control) sample.
Why This Matters (Significance)
- Quality Assurance: Manufacturers use this to verify they are buying the grade of down they paid for (e.g., 600-fill vs. 850-fill).
- Consumer Transparency: It ensures that a jacket labeled as "800 Fill Power" meets that standard, which justifies higher price points.
- Performance Prediction: Higher fill power correlates directly to better thermal insulation efficiency.
Copyright Protection
ASTM International holds the copyright for all its standards. They are not free documents. Distributing or downloading a PDF of ASTM D6307 from unauthorized sources (e.g., file-sharing sites, illegal document repositories) constitutes copyright infringement. Furthermore, using an unauthorized copy in a legal dispute or third-party audit may invalidate your test results, as the document cannot be verified as the current, official version.
2. How often should I recalibrate the correction factor?
The standard recommends determining the correction factor for each unique aggregate blend. Additionally, recalibration should be performed whenever:
- The aggregate source changes
- The aggregate gradation changes significantly
- The ignition furnace is replaced or undergoes major repair
1. Scope
Defines what the test method covers and specifies that it is not suitable for asphalt mixtures containing large amounts of hydrated lime or other materials that decompose during ignition.
Evaluation
- Quantitative Approach: Calculate the reduction in viable microbial counts on the treated sample compared to the untreated sample.
- Qualitative Approach: Observe for zones of inhibition or direct cell counts.
3. Calibration and Correction Factors
One of the most critical sections of the standard involves determining the loss on ignition (LOI) correction factor. Some aggregates (e.g., limestone, slag, or lightweight aggregates) contain hydrates or carbonates that break down and lose mass at high temperatures. The standard mandates a procedure to correct for this, ensuring that the calculated binder content is accurate.
3. Terminology
Defines key terms like ignition furnace, correction factor, and binder content.
