temperature range at which the viscosity of the asphalt is between 50 and 200 centipoise. The mopping behaviour is good and an asphalt film of between 17 and 27 pounds per square is achieved. The EVT of roofing asphalt is the temperature at which the viscosity of the asphalt is 125 centipoise.

• Laboratory mixing and compaction temperatures – intended for determining design volumetric properties of the asphalt mixture – not intended to represent actual mixing and compaction temperatures at the project level.

The new mixing temperaturen range is 173~179℃, and new compaction temperature range is 162~167℃. The decided temperature is lower than the last test results. The mix design result will apply in the city street construction and the total length is abot 1km, and it is trial pavement to estimate the effectiveness of PAC.

Warm mix asphalt (WMA) can be thought of as Hot Mix Asphalt’s cooler relative…not ‘cooler’ in that Fonzie sort of way, but based on the temperature required to produce it. Warm mix asphalt is produced in the 212 to 275 degrees Fahrenheit range, while hot mix is made between 275 to 350 degrees Fahrenheit.

Asphalt driveway installation may be just what you need for a flexible, cost-effective, and quickly completed driveway.

EAPA position paper The use of Warm Mix Asphalt – January 2010 7 vapour remains in the bitumen during compaction reducing effective viscosity and facilitating compaction. On cooling the binder reverts to normal, as the amount of water is insignificant.

the pavement within a specified density range (Series 50, 60, and 70). Because the contractor is responsible for compacting the pavement, then the contractor should have the authority to dictate factors such as mix temperature (165 °C is the maximum), rolling trains, patterns, or passes. References: 1. Standard Construction Specifications 2.

Table A shows the time a contractor has to achieve initial density and compaction with ambient temperatures ranging from 50°F to 90°F, base temperatures ranging from 50°F to 80°F and mix temperatures of 300°F and 250°F.

literature revealed a wide range of reported thermal conductivity values for asphalt concrete and limited information on the specific heat and thermal diffusivity of asphalt concrete. However, mixture types, temperatures, and densities were rarely reported in the literature. Two test methods were developed to measure the required thermal properties.

Warm Mix Asphalt (WMA) is the generic term for a variety of technologies that allow producers of Hot Mix Asphalt (HMA) pavement material to lower temperatures at which the material is mixed and placed on the road. It is a proven a technology that can: Reduce paving costs. Extend the paving season. Improve asphalt compaction.

asphalt concrete mix when that material is placed on top of another existing layer of the pavement structure. Those variables are: air tem- perature; base temperature; mix laydown temperature; layer thickness; and wind velocity. All other factors being equal, as the ambient air temperature increases, the time available for compaction also increases.

Temperature testing in asphalt is essential to verifying the varying degrees of temperature in asphalt mixtures. Our most popular asphalt thermometer is the Pocket Dial Thermometer that has a temperature range of 50 to 500F, an 8" Stem, and a large 2" Dial for easy reading.

Existing driveways of asphalt or concrete can be overlaid with asphalt with excellent results. Usually for driveways, a surface course 1.5 to 2 inches thick will suffice. Before paving, be sure the contractor patches any serious holes or …
