Limestone Powder for Making Asphalt Concrete

Day 27/06/2020

Limestone Powder is an important component in asphalt concrete mixtures. When mixed with asphalt, the fine-grained composition in mineral powder has a particle size smaller than the thickness of the plastic film that hardens the asphalt and creates a mastic mixture with many advanced features such as increased adhesion between stone and resins, increase stability, increase durability in humid environments, reduce cracking and extrusion, … Particles with bigger size than the thickness of plastic films work to fill pores in asphalt concrete, making increase specific gravity and compaction of asphalt concrete.

Limestone Powder (CaCO3) usually accounts about 5% of the hot asphalt mixture.

Limesotne Powders need to be dry and porous when mixed with non-lumped bitumen, capable of absorbing bitumen and must satisfy the mechanical and physical criteria specified in the respective standards (plasticity index, plastic absorption, etc.). ). For grades of super-length roads, super-highways, highways, ports or in cases where the adhesion between stone and resin is unsure, it is necessary to use mineral powder ground from carbonate stone (limestone, dolomite stone, powder lime). When building roads with low tonnage, urban roads, rural roads can use mineral powder derived from crushed stone, baghouse recovery powder. Besides cement, fly ash, marble powder, blast furnace slag powder, … are also used to make asphalt concrete.
