Temperature acts like a conductor for asphalt paving performance. Warmer asphalt becomes more viscous and pliable, allowing for smooth spreading and compaction. This warm, pliable state is ideal for binding aggregate and binder together to create a strong end product.
Temperature can affect the performance of asphalt mixtures in several important ways:
Asphalt viscosity
When it comes to viscosity (a measure of fluidity), asphalt and how to write philippine phone number temperature have an inverse relationship. As temperature increases, viscosity decreases, just like thick honey turning into thin syrup.
The drop in viscosity makes asphalt binder easier to work with. Hot fluid binder allows for smoother mixing, spreading and compacting during the paving process. Cooler temperatures cause asphalt to harden.
Asphalt compaction
A hotter asphalt mix becomes softer and more pliable, allowing the individual particles to move and press together more efficiently during compaction. This process eliminates air voids, creating a denser, more uniform pavement.
