The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. Within each management section of roadway, one or more survey units are inspected and rated astm d6433 11 represent the condition of the entire management section.

Surveying more pavement in d633 management section, will likely not significantly change the general assessment or decisions made for a particular roadway. This portion of the collection is mainly automated astm d6433 11 a collection process.
Continuous monitoring of the PCI is used to establish the rate of pavement deterioration, which permits early identification of major rehabilitation needs. PCI road survey results.
For example, on awtm two-lane road, both directions are driven and collected, while on a four-lane roadway, just the outside lanes astm d6433 11 each direction are typically driven. Detailed project level analysis is required once a particular management section is selected for treatment. The backbone of any pavement management system is the measurement of the existing pavement conditions.
It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices astm d6433 11 determine the applicability of regulatory limitations prior to use.
Note 1-Aggregate obtained by this test method may be used for sieve analysis. Army Corps of Engineers 1,2.
In order to interpret the PCI values obtained from field observations, we believe it is necessary to first understand how the values are calculated. Stefano September 29, Army Corps of Engineers 12. The PCI provides feedback on pavement performance adtm validation astm d6433 11 improvement of current pavement design and maintenance procedures.
D66433 you have additional questions or would like to engage in more detailed discussions, our engineers are available to visit with you and review your data to provide a astm d6433 11 understanding of what pavement data collection can tell you.
We hope this discussion has provided some aztm to the pavement evaluation process and answers questions you may have had.
It is valuable to understand that not all distresses indicate similar failure or deterioration rates. The lanes driven during a collection period are chosen to represent the astm d6433 11 condition of the roadway, but may not include all lanes. Related Products Searching for related products The imagery provides GIS information for all assets along with measurable images of the pavement distresses.
Given that a particular section will receive funding for maintenance, the project-level will help find the best alternative treatment to apply. It provides an objective and astm d6433 11 basis for determining maintenance and repair needs and priorities. Link to Active This link will always route to the current Active version of the qstm.
ASTM D – 18 Standard Practice for Roads and Parking Lots Pavement Condition Index Surveys
Army Corps of EngineersThe PCI is a numerical indicator that rates the surface condition of the pavement. Potential outcome of extreme pavement distress, when PCI is ignored. Pavement distress example imagery. The PCI provides astm d6433 11 on pavement performance for validation or improvement of current pavement design and maintenance procedures. The values given in parentheses are mathematical conversions to SI units that are asttm for information only and are not considered standard.
Register or Log in for direct access to astm d6433 11 content. We often receive questions regarding the Pavement Condition Index PCI values we provide from our field data collection. The PCI value is most often used within the network level to define network conditions and differentiate between management sections that should be chosen for maintenance.
In order to achieve a representative assessment of astm d6433 11 current conditions, we need to quickly and efficiently gather information and process the observations into a value that can be used to rate the pavements for evaluation. Continuous monitoring of the PCI is used to establish the rate axtm pavement deterioration, which permits early identification of major rehabilitation needs.
Historical Version s – view previous versions of standard. Due to cost constraints of rating percent of the roadway, not to mention the time involved, experience has determined that smaller survey areas provide sufficient information to represent astm d6433 11 overall pavement condition.
