Basalt is widely valued for asphalt surface courses because of its high polishing resistance and skid resistance. Yet its dense, abrasive nature accelerates hammer, jaw and cone liner wear and demands careful crushing setup.

Simple impact crushing can over-polish particle faces, lowering surface friction. Quarries need staged crushing that preserves micro-texture on stone surfaces while meeting required gradation bands.

SMP basalt crushing lines combine primary jaw crushing, cone secondary crushing and controlled VSI shaping. The process limits over-polishing and keeps surface roughness for long-lasting road skid resistance.

Correctly processed basalt aggregate helps road contractors build durable highway wearing courses that retain friction after years of vehicle traffic.
