Pothole Patching Mixes
Most pavements will require repairs such as potholes, utility cuts or traffic loading. The kinds of defects may vary from minor abrasions to major holes. Prompt repair can control expenditures and prolong the service life of a pavement. There are a number of different ways of producing the repair material needed.
Emulsions used to make hot mixed cold mix can be either cationic or anionic. They can have very high residue (very little water) or like a conventional asphalt emulsion
They are designed with the proper solvents to ensure that the cold mix has low temperature workability and high temperature stability. They are used in the production of conventional cold mix. They have unique formulations that resists stripping and bleeding. Emulsions available are CCM5, ACM5, CCP3 and HF1000M. There are also polymer versions available.
Cutback asphalt used for the cold mix patch process is SC800. The cold patch material is produced in a hot mix plant. The cold mix has the appearance of regular surface hot mix but has low temperature workability and cohesion. Both are normally developed to have a minimum stockpile life of at least six months.
Specialty asphalt used to produce the proprietary cold patch is designed and formulated to produce MACPATCH cold mix, which is classified as a high-performance cold mix. The finished liquid has a unique formulation that provides resistance to stripping and bleeding and gives excellent aggregate coating.
