<p><p><h2>Preferred Design Procedure</h2>Blast densification currently has no recommended FHWA design guidance. There are two existing methods for blast densification design including one method based on empirical calculations and test blasts and another method that estimates results using energy input. Neither design method is proprietary.</p><p>It is recommended that the design procedures be combined, using the method for estimating results through energy input to improve the results of the empirical design procedure. This document contains summaries of the two methods. Table 2, illustrates typical inputs and outputs for design and analysis procedures.</p></p>
