Asphalt Pavement Thickness and Mix Design | Asphalt Institute

Mix temperature is dependent on the grade of asphalt used in the mix. Less viscous the asphalt requires lower the temperatures, while more viscous asphalt requires higher temperatures.At the start of a mix design project, target temperatures are specified for proper mixing and compaction.

Evaluation of Crumb Rubber in Hot Mix Asphalt - Rutgers CAIT

May 15, 2018 · An asphalt-rubber hot mix asphalt (AR-HMA) design was created using a Superpave 12.5mm gradation and a #30 (-) mesh crumb rubber at 20% total weight of the asphalt binder. At this point in time, asphalt rubber has only been used with HMA that contains a more open graded nature, such as open graded friction course (OGFC).

Asphalt Calculator - How much asphalt do you need?

Many road builders and just people who want a nice driveway to their home are faced with estimating the amount of Hotmix Asphalt (HMA, also bitumen, blacktop, Tarmac) they need to cover a given area with it. Our asphalt calculator is of great utility in such cases, but you should keep in mind that the results will only be as good as the measurements entered into it. Also, we use a standard asphalt density of 145 lbs/ft3 (2322 kg/m3) which may be somewhat different depending on the precise asphal

SUPERPAVE ASPHALT CONCRETE

The bid price for the asphalt mix will include the cost of the liquid asphalt or the asphalt recycling agent. There will be no separate payment or unit price adjustment for the asphalt binder material in the asphalt mix. For the calculation of unit price adjustments of bituminous material, the asphalt content will be based on the percentage ...

Warm Mix Asphalt (WMA) A typical WMA is produced at a temperature around 20 – 40 °C lower than an equivalent Hot Mix Asphalt. Less energy is involved and, during the paving operations, the temperature in the mix is lower, resulting in improved working conditions for the crew and an earlier opening of the road.
