Semi Hot Pave

Outline

Warm Mix Asphalt (Product name: Semi Hot Pave) is a mixture allowing the tempreture at the time of production and construction to be lowered by about 30℃ by adding a special additive agent (Semi Hot Support) in the plant-mixing method.

Characteristics

• Even after lowering the tempreture, it still has mixing performance and compaction degree equivalent to those of normal mixture. For this reason, it can secure performance and construction ability equivalent to normal asphalt mixture.
• Even with construction in cold seasons and of thin layer pavement, which are generally difficult with lower tempreture mixture, production tempreture dose not need to be increased too much for application.

Comparison of mixture properties between Normal Mixture and Semi Hot Pave (Example)

CO₂ emission reduction (Example)

The emission of CO₂ in the heating process of production can be reduced by 16% compared with normal mixture.

Early opening of traffic (Example)

Traffic can be opened about 40 minutes earlier than with the normal mixture.
