Product overview
What PHPM-50 is built to do

Product benefits
Why crews specify it
Performance depends on pavement condition, preparation, equipment, weather, traffic, and application.
02
Patch-Mix Compatible
PCT specifies compatibility with all patch mixes, simplifying use across maintenance programs.
03
Liquid Stable
Formulated not to gum up, become viscous, or clog application equipment.
04
Longer Patch Life
PCT states that PrimePatch can increase patch life by up to five times by helping stop water infiltration.
Field planning
From product fit to deployment
Product fit is only the first decision. The field plan still needs project-specific rates, equipment checks, safety documents, and acceptance criteria.
Prepare the repair
Remove loose debris and prepare the pothole or overlay surface in accordance with the patch-mix and agency requirements.
Apply the membrane
Use PrimePatch as the tack membrane. The liquid-stable formula is designed to avoid gumming or clogging equipment.
Place the patch mix
Install the selected compatible patch mix or overlay while following its placement and compaction requirements.
Protect stored material
No application heat is required, but PCT specifically calls for freeze protection during storage.
Project details to confirm
Confirm the current storage temperature, placement procedure, traffic reopening criteria, application rate, package size, and compatibility requirements before use.
