LIME IN ASPHALT
Establishing a standard of safety and cost-effectiveness.
Hot-mix asphalt uses lime as an anti-stripping additive and as mineral filler. This adds years of life to highways, establishing a standard of safety and cost-effectiveness.
Hydrated lime reduces stripping, rutting, cracking and aging. When hydrated lime is used alone, it substantially improves these properties, but it also works well in conjunction with polymer additives. When lime is used in this way it helps create pavement systems that will perform to the highest expectations for many years.
The filler effect is a result from oxidative hardening and improves resistance to high-temperature rutting and adds fracture toughness at low temperatures— Something needed in Texas’ temperamental weather.
