Initial site preparation
Prior to establishing the site it may be necessary to pre-mill the site. This work should be done with a profiler, not a reclaimer. Pre-milling may be to break down asphalt layers that are severely distressed and also to eliminate oversized particles such as asphalt chunks.
Pre-pulversing is required if:
depth of cut may be variable;
the material needs to be cross blended to achieve uniformity;
materials exhibit plasticity that requires modification; or
The recycling depth requires more power than can be constantly delivered.
See Section 12.2.2 of the Pavement Recycling and Stabilisation Guide - Site preparation - for more information.
The Guide is available to purchase through EA Books.
