Tips about milling

Posted by Michael Harris on February 3rd, 2020

Asphalt or cement milling is a process that removes defects from the pavement for safety and driveability reasons. Some of the road problems that milling can rectify are as follows:

Shoving: a washboard appearance opposite travel direction 
Ride quality: uneven road surface such as bumps or indentions 
Damage: caused by impact or fire
Raveling: loose aggregate separates from binder and litters the road
Bleeding: the binder rises to the surface of the road
Rutting: occurrence of low spots in pavement usually along the wheel path

The process of milling asphalt or cement (also called cold planing or profiling) is the removal process of a paved surface. Surface milling or full-depth removal might be necessary based on the desired result and the level of deterioration experienced.

Milling generates the aggregate needed to create the new asphalt to be used in resurfacing or repair. This repurposing is better for the environment than full removal with new asphalt applied thereafter.

The Asphalt Recycling and Reclaiming Association has instituted classes of cold planing that the Federal Highway Administration has recognized. They are:

Class I - milling to remove surface irregularity
Class II - milling to uniform depth as shown on plans
Class III - same as class II with the addition of cross-slope
Class IV - milling to the subgrade (full depth)
Class V - milling to different depths at different areas

A specialist, such as the experts at Parking Lot Striping Jefferson AL, can meet all your needs regarding milling and address any of your asphalt or pavement issues. These matters are best left in the hands of trained professionals
