Suggested Citation:"Chapter 2 - Survey to Determine the Density of Asphalt Pavements." There is not even a consensus on the reference density that is used for the calculation of the percent density.

The control asphalt model consists of three components: asphaltenes, aromatics, and saturates. This modified asphalt model was verified through density calculations and comparisons.

EXCUTIVE SUMMARY. In-situ asphalt mixture density is critically important to the performance of flexible airport pavements: density that is too high, or too low, may cause early pavement distresses.

T 312 Preparing and Determining the Density of the Hot-Mix Asphalt (HMA) Specimens by Means of the Superpave Gyratory Compactor . 2.2 . Asphalt Institute 2.3 . ASTM Standards 2.4 ... combinedaggregate bulk specific gravity and subsequentVMA calculations.The Agency may. choose to specify adjustments to the VMA requirements to account for this ...

The gradation should not be too close to the FHWA's 0.45 power maximum density curve. If it is, then the VMA is likely to be too low. Gradation should deviate from the FHWA 's 0.45 power maximum density curve, especially on the 2.36 mm (No. 8) sieve. Asphalt Binder Evaluation

Measuring Asphalt Density- Does a Day Make a Difference? Density or degree of compaction is one important component of asphalt pavement quality and long-term performance.

GSSI's PaveScan RDM Asphalt Density Assessment Tool. Achieving proper density is key to avoiding premature Asphalt density variations create varying reflections that are picked up by the system.

Calculate Asphalt in Tons . Need to calculate asphalt in tons? Here is a simple step by step process with an example: Step 1 - Determine the dimensions (Length, Width, and Depth) in feet of all areas requiring asphalt. ex: 2 inches of asphalt / 12 = .167 feet (2" = 0.167') Part A: 10 foot wide . 50 foot long .

An asphalt density lot size shall equal one paving day's production per mix. A lot shall be divided into a minimum of five equal sublots. A sublot shall not be greater than 500 tons. When a paving day's production per mix is greater than 2,500 tons, then each sublot size shall be 500 tons or fraction thereof

correction for thermal expansion of asphalt (Figure 5), g; density of water at the test temperature, Curve D in Figure 6, Mg/m3; and density of water at 25°C (77°F), Mg/m3.

Here, the Density of Asphalt is taken as 2400 kg/m3. The Quantity of Asphalt = Volume of Asphalt x Density of Asphalt. The Quantity of Asphalt = 18000 x 2400 = 43200000 Kg. Quantity of Asphalt in Tons = Quantity of Asphalt / 1000. Quantity of Asphalt for Road in Tons = 43200000 / 1000 = 432000 Tons.

Typical values for theoretical maximum specific gravity range from approximately 2.400 to 2.700 depending on the aggregate specific gravity and asphalt binder content. Unusually light or heavy aggregates may result in a value outside this typical range. Calculations (Interactive Equation) Calculate and report Gmm to the nearest thousandth.

The paver operator, the paving mix, even the distance from the asphalt plant to the jobsite all play a role in achieving optimum mat density. But the last person to touch the pavement is the roller operator.
