Investigation of issues arising in these areas is pursued both through the development of theoretical models and through the empirical testing of those models.
The frameworks developed in recent decades, the data gathered, and the empirical testing done have been useful and have advanced the profession's understanding of macroeconomic processes.
The empirical testing methods and Superpave grading procedure that were developed mainly for unmodified bitumens have failed in many cases to predict the performance of modified bitumens.
Section 5 explains the empirical testing of the hypothesis.
This scale is so remote from current experimental capabilities that the empirical testing of quantum gravity proposals along standard lines is rendered near-impossible.
