Standard Test Method for Evaluation of Asphalt Mixture Cracking Resistance Using the Semi-Circular Bend Test (SCB) at Intermediate Temperatures

Importancia y uso:

5.1 The critical strain energy release rate parameter, J_c, is used to compare the cracking resistance of asphalt mixtures prepared with different asphalt binder and aggregate types prepared to meet the volumetric requirements of differing traffic levels tested at intermediate temperatures.

5.2 The critical strain energy release rate parameter, J_c, is an engineering property and a performance indicator at intermediate temperature cracking.

Note 1: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
