Laboratory Mixing and Compaction Temperatures for …
– Mixing temperature • can best be defined as the temperature at which the aggregate can be sufficiently and uniformly coated. • As with the lab temperatures, the mixing temperature should not exceed 177°C (350°F). – Compaction temperature • usually in the range of 135-155°C (275-310°F)
Why Tracking Temperatures is Key to Successful Asphalt …
Why Tracking Temperatures is Key to Successful Asphalt Paving. The temperature of the mix on the base after it has passed through the laydown machine – not the mix or manufacturing temperature -- is the most important factor in determining the available time for compaction. Hot mix asphalt pavement arrives at a project at temperatures between 275°F...
Asphalt /bitumen flow measurement by Coriolis mass flow meter
Asphalt flow measurement is always a technical problem because of the high viscosity and poor fluidity. The operation temperature of the pipeline liquid asphalt is usually around 200 ° C. Although the temperature is very high, the viscosity is still large, and the medium contains a small amount of solid part
Asphalt-Rubber Systems - CEI Enterprises
Portable Mixing Unit. Then, the GTR is blended with virgin asphalt by a high shear mixer running at a speed of 3400 rpm. As the materials are mixed, they are pumped to the portable holding tank. During the mixing process, fresh materials are continuously fed into the chamber until the required volume of material has been mixed.
Mixing shall be done with a twin shaft pug mill-type …
Paving grade asphalts shall be added to the aggregates, in both batch and drier-drum plants, at a temperature between 285EF (140EC) and 350EF (177EC). The temperature of the aggregates at the time of adding the asphalt cement shall not be less than 265 EF (130EC), nor more than 325 EF (163EC).
