MIXING AND COMPACTION TEMPERATURES OF ASPHALT MIXTURES WITH ...

the bitumen temperature is too high, low viscosity, bitumen can drain off the asphalt mixture during transport. On the other hand, if bitumen temperature is too low, high viscosity, not all aggregate particles will be coated [2, 3]. After the mixing process, asphalt is transported to field; it is spread and compacted at a predefined temperature ...

Cohesion of bituminous binders and asphalt concrete ...

The mixing time for bitumen BND 90/130 with polymer was increased while enhancing the polymer content: ranging from 1 hour for PMB with 3 % of SBS to 1,5 hours for PMB with 6 % of SBS and 2 hours for PMB with 10 % of SBS. Bitumen cohesion was measured at 25 °C and shear rate of 1 s-1.The properties of bituminous binders are given in Table 1.

What Temperature Should Asphalt be Laid? Ideal Temp for ...

Asphalt is a fantastic product, but it takes the right temperature on both the ground and in the air for proper installation. Generally, the best temperature for asphalt installation ranges from 50 to 90, so most of the country can only install asphalt during the warmer months.

7 Pro Tips on Temperature Requirements When Laying Asphalt

Nov 03, 2020 · To know at what temperature you can lay asphalt, first note that asphalt is mixed in a drum, typically at 280 degrees Fahrenheit on average, and then installed while still warm. This is done because asphalt is a mixture of aggregates or crushed stone, a petroleum-based bitumen …
