The water will pond below the surface of the flex Base, creating soft spots in the subgrade (not the flex Base) which in turn will create potholes over time. Spend the time or extra money when hiring a professional to do your grade work to ensure that the subgrade (the area below the flex Base) has been graded properly to ensure water flow.
In addition to having a uniform mixture, each lift of loose base material should be graded properly. Gradation is the percentage by weight of different-sized particles in a mixture. Proper gradation helps a material obtain strength. The strength of a raw aggregate depends partially on the unit weight of the total material.
A. Aggregate for the two classes of aggregate bases at the time the base material is deposited on the prepared sub grade or sub base shall conform with ASTM D1241 and the following requirements: 1.

All GAB materials were non-plastic and their as-received fines content ranged from 6.9% to10%. According to SHA specifications, the fines content of the GAB materials used in highway base layers must be less than 8% (SHA 2012). The absorption of fine and coarse aggregates of GAB materials varied between 0.89 and 5.33% and 0.4 and 0.79%

Products in this range are notably more compactible and suited for creating a base layer -such as Crusher Run, Screenings, Sand and Soil. For support of heavy vehicles – choose our #3 or #4 stone. For standard driveways – choose our #57 or #67. For more elaborate driveways – choose our 1/2" to 2" river gravel.
Subbase Course is the layer of aggregate material of the pavement structure placed on the subgrade. Subbase is often the main load-bearing layer of the pavement structure. Its role is to spread the load evenly over the subgrade. This material is typically unbound granular material and is very important for the useful life of the road.

Density is also called as unit weight of substance. It is represented by symbol called row ( p). Density represents the degree of compactness of material. If the material is of more density, it is more compacted material. Density is defined as the ratio of mass to volume. p = m/v Units = kg/m 3 or lb/ft 3 Conversion: 1 kg/m 3 = 0.624 lb/ft 3.
