Hot-mix asphalt paving mixture
A hot-mix asphalt paving mixture includes the use of a hard, angular, non-carbonate ½″ minus igneous crushed rock, washed rounded No. 100 sieve silica sand particles, ½″ minus recycled asphalt pavement particles, and a performance-graded bituminous liquid asphalt binder, thereby to produce an environmentally-friendly hot asphalt mixture that is laid with minimal compaction effort, and without the use of conventional compaction-aiding additives that chemically alter the viscosity of the liquid asphalt binder. During compaction, the rounded silica sand particles react with the igneous rock particles as a mechanical compaction aid, thereby allowing the angular particles to achieve proper aggregate interlock with minimal compactive effort. The aggregate composition comprises about 75% igneous crushed rock, about 5% processed round silica sand particles, about 20% recycled asphalt pavement, and about 5% binder. The resultant pavement is skid-resistant, resists rutting, and has a permanent dark color.
