Why Tracking Temperatures is Key to Successful Asphalt …

When there is wind, the temperature of the hot mix asphalt pavement will cool faster than normal. The higher the wind velocity the quicker the hot mix asphalt will cool.

Temperature Range for Hot Mix Asphalt | Top West Asphalt

In general, though, the minimum temperature ranges from approximately 107 C to 121 C. The working temperature is adjusted based on project conditions, but should normally never rise above 135 C. Based in Abbotsford, Topwest Asphalt also serves Langley, Chilliwack, Mission, and Maple Ridge.

Getting started with warm mix asphalt - NYSDOT Home

2. Begin warm mix asphalt (WMA) production gradually and lower the mix temperature to within + 10°F of the WMA target temperature. 3. Check loaded transports to assure that the mix tempera-ture has stabilized and proceed to reduce to target WMA temperature. 4. Monitor conveyor and mixing motors for power demand.

Asphalt Pavement Construction - Asphalt InstituteAsphalt ...

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

Asphalt

The temperature required varies depending upon characteristics of the asphalt and the aggregates, but warm-mix asphalt technologies allow producers to reduce the temperature required. [70] [15] The weight of an asphalt pavement depends upon the aggregate type, the asphalt, and the air void content.

Roofing 101 – Part Two | Asphalt magazine

At the moment the asphalt ball touches the plate, the temperature of the liquid is determined, and this is designated as the ring-and-ball (R&B) softening point of the asphalt binder sample. It is important to note that for asphalt materials, the softening point is not the same thing as the melting point.

Asphalt Heating and Circulation - tpub

Asphalt Heating and Circulation Provisions should be made for the circulation of the asphalt through the feeding and storage system. All storage tanks, transfer lines, and pumps should have heating coils and/or jackets to maintain the asphalt at the required temperature.

Determining Lab Mixing and Compaction Temperatures for ...

Asphalt Institute Technical Advisory Committee. The Asphalt Institute recommends that, for unmodified asphalt binders, the laboratory mixing and compaction temperatures should be determined where the viscosity‐temperature line crosses the viscosity ranges of 0.17 ± 0.02 Pa‐s (mixing temperature range) and 0.28 ± 0.03 Pa‐s (compaction temperature range).
