Will there be any negative implications of RAP on soil and water when stored in open for a long period of time
You may find this helpful. The rules may change by country and laws. For surface and groundwater integrity, the conservative approach may be limit to upland disposal sites.

Another approach with benefit is recycling material into fresh asphalt or crushing and reusing with gravel surfacing for spreading on low traffic roads. With hot sunny weather, the RAP with gravel surface tends to bind together with traffic. I have seen this gravel mix approach used only once, but impressed. I have also seen RAP deposited on land. It made the surface basically unusable, but perhaps some sites for snakes, mice, etc. It has no scenic appeal.
not recommended to do so .. because storing it in an open environment will cause aging.. and become more stiff and brittle
