Cold-mix patch is useful when plant material or full repair conditions are unavailable, especially for temporary hazard reduction. Hot-mix asphalt is generally used for planned permanent repairs when the failed material can be removed, edges prepared and the replacement compacted in a defined repair section.
What determines the scope
The lasting result depends on more than mix temperature: water, unstable base, shallow repair depth, poor edge preparation and inadequate compaction can cause either repair to fail. State whether the patch is temporary or permanent in the scope.
What a commercial proposal should define
- Document existing failures and drainage.
- Define repair limits and depth assumptions.
- Plan access, closures and traffic control.
- Confirm jurisdiction and applicable requirements.
- Put materials and exclusions in the written scope.
How to compare bids
Compare the same repair boundaries, depths, materials, preparation, access plan and exclusions. A lower number is not a comparable bid when it assumes a thinner section, skips failed base, omits traffic control or leaves drainage and striping unresolved.

Property-manager action
State whether a patch is temporary or permanent and address water, unstable base, edges and compaction in the repair scope.

Frequently Asked Questions
What should be included in a Cold Mix vs Hot Mix Asphalt Patching proposal?
The proposal should define repair limits, depth and material assumptions, preparation, traffic control, access, schedule conditions, exclusions and any connected drainage, concrete or striping work.
Can the work be completed while the property stays open?
Often it can be phased, but the workable plan depends on entrances, fire and accessible routes, deliveries, parking demand, cure or cooling time and the amount of safe staging space.
How do we know whether repair or replacement is appropriate?
The decision starts with the failure pattern and supporting conditions. Isolated sound areas may be preserved, while widespread movement, unstable base or drainage failure can require deeper correction.
