Pavement Surface Evaluation & Rating System

What is PASER?

Pavement Surface Evaluation and Rating (PASER) is a system for visually rating the surface condition of a pavement from a scale of 1 to 10, with 1 being a pavement in a failed condition and 10 being a pavement in excellent condition. Guidelines for rating the pavement surface using the PASER system have been developed by the Michigan Transportation Asset Management Council.

Lansing has conducted pavement rating analysis since 2002. The 2007 report can be found here. An updated 2013 report will be available soon. The city began a 3 year analysis cycle in 2010 with approximately one third of the streets being evaluated each year.

Why does the City conduct a pavement survey?

Pavements age with time and gradually deteriorate due to environmental effects and traffic loadings. Resources for maintaining and repairing roads can be efficiently managed so that the money is spent in the right place at the right time by knowing the condition of the pavement network. The City of Lansing has recognized the benefits of performing regular pavement condition surveys to evaluate the existing pavement conditions and to allocate maintenance and construction funds. The pavement survey is one aspect of a larger asset management program not only for pavements but for all infrastructure in the City.

What do the PASER ratings actually mean?

Most pavements will deteriorate through various phases as shown. The rate at which pavement deteriorates from an excellent (10) to a very poor condition (1) depends largely on its environment, traffic loading conditions, original construction quality, and interim maintenance procedures. Two pavements constructed at the same time may have significantly different lives, or certain portions of a pavement may deteriorate more rapidly than others, due to material or construction problems.

The PASER rating scale can generally be translated into maintenance categories as shown. The normal maintenance or rehabilitation procedure has been found helpful in relating to the surface rating scheme. However, choosing an individual surface rating should not automatically dictate the final maintenance or rehabilitation technique. Future traffic projections, original construction and pavement strength should be considered since these may dictate a more comprehensive rehabilitation. On the other hand, it may be appropriate under special conditions to do nothing and let the pavement fully deteriorate, then rebuild when funds are available.
