PDF Determining Asphalt Content for Recycled Asphalt Pavement

Conventional means of measuring asphalt cement contents as a percentage involve physically determining the mass of the asphalt cement. An alternate strategy is to solve for the asphalt cement content using standard volumetric equations for HMAC.

Determination of Asphalt Content and Characteristics of

1. Compared to the reflux extraction procedure, nuclear asphalt content gauges determine asphalt content of bituminous mixes with much greater accuracy and comparable precision. 2. As a means for determining asphalt content, the nuclear proce­ dure should be used as an alternate to chemical extractions whenever possible.

DETERMINATION OF ASPHALT CONTENT OF BITUMINOUS

This test method provides a procedure to determine the asphalt binder content of bituminous paving mixtures by removing the asphalt binder via pyrolysis. Bituminous mixture samples are placed in a furnace and heated past the autoignition point of the asphalt binder (typically ranging from 420 to 570°C).

PDF Quantitative Extraction of Asphalt Binder from Hot Mix

The asphalt binder content is calculated by differences from the mass of the extracted aggregate and moisture content, and mineral matter in the extract (when using centrifuge extraction from Test Method A and when using the automated extraction in Method F . The asphalt binder content is expressed as a mass percent of moisture-free mixtures.

Binder Content – Pavement Interactive

The ignition method of determining asphalt binder content allows for the asphalt binder in an HMA sample to be burned off in an oven (Figure 2) at temperatures above the flame point of the binder. Asphalt binder content is then calculated by subtracting the mass of the aggregate remaining after the asphalt binder is burned off from the initial

8.15 Calculate the asphalt content of the sample according to Section 11.1. Note 9—Asphalt content reported by the ignition oven may be used if proven accurate. 8.16 Empty the contents of the basket into a flat pan. Use a small wire sieve brush to ensure removal of any residual fines from the basket. Add those fines to the contents in the flat pan.

Concrete vs Asphalt Driveways: Which is Better?| Mashvisor

The cost of a concrete driveway is almost double the cost of an asphalt driveway. According to Cost Helper, the cost for a new concrete driveway is about $3 - $10 per square foot, while a new asphalt driveway costs around $2 - $5 per square foot. The price can fluctuate depending on the location, the size of the driveway, and the complexity
