In an asphalt mix weighing 3,020g, with aggregate weighing 2,865.98g, what is the percentage of asphalt by weight of the mix?

To determine the percentage of asphalt by weight in the asphalt mix, you first need to find the weight of the asphalt itself. This can be calculated by subtracting the weight of the aggregate from the total weight of the mix.

The total weight of the mix is given as 3,020g, and the weight of the aggregate is 2,865.98g. Therefore, the weight of the asphalt can be calculated as follows:

Weight of asphalt = Total weight of mix - Weight of aggregate

Weight of asphalt = 3,020g - 2,865.98g

Weight of asphalt = 154.02g

Next, to find the percentage of asphalt by weight, you can use the formula:

Percentage of asphalt = (Weight of asphalt / Total weight of mix) × 100

Percentage of asphalt = (154.02g / 3,020g) × 100

Percentage of asphalt = 0.0510 × 100

Percentage of asphalt = 5.10%

Thus, the percentage of asphalt by weight of the mix is 5.10%, making this the correct answer. This calculation displays how to apply basic principles of weight percentage to assess the composition of materials in an asphalt mix
