Asphalt Millings Calculator
Understanding Asphalt Millings and This Calculator
Asphalt millings, also known as milled asphalt or RAP (Reclaimed Asphalt Pavement), are the material generated from the grinding down of existing asphalt surfaces during resurfacing or road repair projects. This material is highly valuable as a cost-effective and environmentally friendly alternative to virgin asphalt for various applications.
Common Uses for Asphalt Millings:
- Driveways: A popular choice for its durability and lower cost compared to traditional asphalt.
- Parking Lots: Suitable for smaller lots or as a base layer for new asphalt.
- Road Base: Excellent for stabilizing unpaved roads, farm lanes, and construction entrances.
- Erosion Control: Can be used to manage water runoff on slopes and around structures.
- Landscaping: For pathways or decorative borders.
How This Calculator Works:
This calculator helps you estimate the quantity and cost of asphalt millings needed for your project. It takes into account the dimensions of your area, the desired depth of the millings, the typical density of the material, and its cost per ton.
Calculations Performed:
- Calculate Area: The length and width of your project area are multiplied to find the total square footage.
Area (sq ft) = Length (ft) * Width (ft)
- Calculate Volume: The area is then multiplied by the desired depth, converting inches to feet, to find the volume in cubic feet.
Volume (cubic ft) = Area (sq ft) * (Depth (inches) / 12)
- Convert to Cubic Yards: Since materials are often sold by the cubic yard, the volume is converted.
Volume (cubic yards) = Volume (cubic ft) / 27
- Calculate Weight: Using the provided density, the total weight of the millings is estimated.
Weight (lbs) = Volume (cubic yards) * Density (lbs/cubic yard)
- Convert to Tons: The weight is converted from pounds to tons for easier cost calculation.
Weight (tons) = Weight (lbs) / 2000
- Calculate Total Cost: The total cost is determined by multiplying the weight in tons by the cost per ton.
Total Cost ($) = Weight (tons) * Cost per Ton ($)
Note: The density of asphalt millings can vary depending on the source and composition. A common average is around 1200 lbs per cubic yard, but it's always best to confirm with your supplier. It's also wise to order slightly more material than calculated to account for settling and potential unevenness in the sub-base.
