Standard Test Method for Evaluation of Durability of Rock for Erosion Control Under Wetting and Drying Conditions

Importancia y uso:

5.1 Rock for erosion control consists of individual pieces of natural stone. The ability of these individual pieces of stone to resist deterioration due to weathering action affects the stability and longevity of the integral placement of rock for erosion control and hence, the stability of construction projects, structures, shorelines, and stream banks.

5.2 This test method is designed to determine the effects of wetting and drying action on the individual pieces of rock for erosion control and the resistance of the rock to deterioration. This test method is used in conjunction with additional test methods listed in Practice D4992. This test method does not provide an absolute value but rather an indication of the resistance to wetting and drying. Therefore, the results of this test method are not to be used as the sole basis for the determination of rock durability. The data is summarized, and any interpretations of the data are made by the end-user or client.

Note 1: The quality of the result produced by this standard is dependent upon the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluation some of those factors.
