The performance of a pavement structure is directly related to the properties and conditions of the roadbed soils and pavement materials. The design procedures in this manual are based on the assumption that most soils can be adequately represented for flexible pavement design by their corresponding resilient modulus (M R) values. However ...

Pavement Preventive Maintenance Guidelines Page 6 Crack Sealing - Flexible, Composite and Rigid Pavements Description & Purpose: Crack Sealing is the placement of a mixture of a neat or modified binder, such as a PG64-22, mixed with polyester or polypropylene fibers, into existing cracks in the pavement. Crack Sealing is used
Maintenance actions, such as crack sealing, joint sealing, fog seals and patching help slow the rate of deterioration by identifying and addressing specific pavement deficiencies that contribute to overall deterioration. Rehabilitation is the act of repairing portions of an existing pavement to reset the deterioration process.
MnDOT's Pavement Distress Identification Manual is located at the MnDOT Pavement Management Website. The MnDOT Pavement Management Unit performs visual surveys on all state highways and interstate routes using pavement management collection vans. Most distresses are recorded for the first 500 feet of every mile.

pavement distress types and defining the levels of severity and extent (area, length, count) associated with each distress. This manual is intended to be a training aid for pavement raters and a field reference during the rating process. In performing pavement inspec-tions, you, the pavement condition rater, should be able to identify each ...
Types of Pavement Maintenance Pavement maintenanceis the key to pavement preservation. An effective pavement preservation program integrates many maintenance strategies and treatments. There are three types of pavement maintenance: Preventive Maintenance:Planned strategy of cost-effective treatments to an existing roadway system and its
