Stabilized Decomposed Granite

For each 2" lift evenly spread the material over area of concern. Grade and smooth as desired. Thoroughly water entire area so that the entire depth of the material is moist. After a period of +/- 6 hours compact the finale lift with a 1000-3000lb drum roller. Allow for a sufficient curing period of +/- 4 days prior to use.

For pathways, Stabilized decomposed granite shall be placed to a minimum depth of 3" compacted. For driveways or vehicular roadways Stabilized decomposed granite shall be placed to a minimum depth of 4" compacted over a DOT approved base.

Natracil organic binder shall have a minimum swell volume of 35 ml/gm. The binder shall be incorporated with the granite fines by the use of a pug mill that includes a weight belt feeder that insures the proper ratio of binder to granite fines. Blending with the use of a bucket loader or similar is not acceptable. For pathways the binder shall be blended at the rate of 12 lbs. per ton of granite fines. For parking lots or roadways the binder shall be incorporated at the rate of 14 lbs. per ton.

Decomposed granite as produced by Gail Materials (951-279-1095) is derived from the crushing and screening of naturally friable granite. The blending of course sand with rock dust is not an equal product. The granite is screened to include stone particles of 3/8" minus. The particles that pass the 200 screen mesh as determined by ASTM methodology shall not exceed 18 percent. The sand equivalent shall be a minimum of 30.

Natracil is a stabilizing organic binder that is non-toxic, buff in color and without a marked odor. The swell volume shall have a minimum of 35ml/g with a minimum mucilliod content of 80 percent. The light extraneous matter shall not exceed a maximum of 20 percent with the heavy extraneous matter not exceeding 5 percent. The material shall be finely screened with 90-100 percent of particles passing the standard 40 mesh screen.
