  • Open-Graded Base Courses for Slabs-on-Ground

    ASTM No. 57 and No. 67 coarse aggregates are examples of such materials. Such open-graded (permeable) base courses are intended to serve as subdrainage layers in concrete pavements and as a capillary break that prevents liquid water from rising to the bottom of interior concrete slabs through capillary action in the base course.

ASTM has created a numbering system to classify rocks and crushed stone based on its size. ASTM number 57 stone is large enough to allow drainage while supporting asphalt and cement. It is used in road beds, foundation beds and gravel walkways.See more on hunker
  • The Construction and Design of Concrete Slabs on Grade

    A layer of open graded, clean, compacted coarse aggregate is usually needed as a capillary break when a floor will be built on sandy soils or very fine soils (more than 45% of the particles by weight passing the No. 200 sieve). The capillary break usually consists of a 4 to 8 inch thick layer of 3/4 inch washed, single size aggregate.

  • Maintaining Slab Subgrade Concrete Construction Magazine

    2008-02-01  Thickened aggregate base course can be considered above the soil sub-grade to resist weather and construction traffic. When using a thicker aggregate subbase, it is important to watch the fines content in the aggregate. Even though some state transportation departments allow up to 15% fines for typical dense-graded aggregate, many aggregates become sensitive to moisture and traffic

  • Subgrade and Subbase for Concrete Slabs - The Constructor

    4. Subbase for Concrete Slab. Subbase is a layer of gravel, which is fairly cheap material, placed on top of subgrade. The subbase placement is optional and it serves as a work platform for construction of the slab and provide more uniform support for the slab. As the thickness of subbase increases, the ultimate load carrying capacity of slab ...

  • Subgrades Subbases for Concrete Slabs - The Concrete Network

    2018-07-31  And in some ways that's good, because slabs curl and if the base can deflect a little, it can continue to provide support for the slab even when it curls. But if it doesn't provide uniform support, if the slab has to bridge over soft spots, the slab will probably crack. There doesn't even need to be much of a load on the slab--its own weight is usually enough since a slab on grade is not ...
