#9 Stone (IDOT) in #16 to #4 Size Range
#9 stone with the IDOT specification in a #16 to #4 size range is a finely crushed aggregate commonly used in construction and infrastructure projects. Produced by mechanically crushing larger stones, this material is screened to ensure particles fall between the #16 (about 1.18 mm) and #4 (about 4.75 mm) sieve sizes, resulting in a uniform, fine gravel.
The fine gradation of #9 stone makes it ideal for applications requiring excellent compaction and a smooth, stable surface. Its IDOT (Illinois Department of Transportation) certification ensures consistent quality and performance, making it a preferred choice for road base layers, asphalt mixes, and as a leveling course beneath pavers or concrete slabs. The smaller particle size allows for tight packing, reducing voids and providing a solid foundation, though it may not be suitable for drainage applications where larger, more open-graded stone is needed. This aggregate is valued for its versatility, ease of handling, and reliable performance in both residential and commercial settings.Applications & Uses
