Conclusions

  1. 1.

    Rock materials containing up to 30% weathered rock possess adequately high structural properties and can be used for the construction of earth-and-rockfill dams. The use of these materials is one of the basic factors responsible for a significant reduction in capital outlays in hydraulic construction, up to 20% for the project in question.

     
  2. 2.

    The presence within allowable limits (according to Standard Norms and Specifications II-53-73) of clayey particles in the end products of weathering, which form under natural conditions during the service life of a structure, serves as the basic criterion for solving the problem of the applicability of rock material from weathered strata.
