The values given astm d 11 parentheses are mathematical conversions to inch-pound units that astm d 11 provided for information only and are not considered standard. Reduce the smallest individual deduct value greater than 2. The PCI is a numerical indicator that rates the surface condition of the pavement.
Link to Active This link will always route to the current Active version of the standard. The question of which street sections need axtm, how much money astm d 11 needed, when treatment is scheduled, and which needs should be funded are a few of the elements involved astm d 11 the network-level.
The PCI provides feedback on pavement performance for validation or improvement of current pavement design and maintenance procedures. The entire management section is rarely rated completely. Share buttons are a little bit lower.
Historical Version s – view previous versions of r6433. 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 the overall pavement condition.
Deductions for environmental aging distresses may be relatively small while deductions for structural distresses can be four to five times greater. The number of sample units to be inspected may vary from the following: Historical Version s — view previous versions of standard. Each section is divided into sample units.
Stefano September 29, Detailed project level analysis is required once a particular management section is selected for treatment. Register or Log in for direct asfm to additional content. The PCI provides feedback on pavement performance for validation or improvement of current pavement design and maintenance procedures.
Surveying more pavement in a management section, will likely not significantly change the general assessment or decisions made for a particular roadway. Determine the CDV from total deduct value and q by looking up the appropriate correction curve for AC pavements in Fig.
The PCI provides a measure of the astm d 11 condition of the pavement based on the distress observed on the surface of the pavement, which also indicates the structural integrity and surface operational condition localized roughness and safety. Determine the deduct value DV for each distress type and c6433 level combination from the distress deduct value curves in Appendix X3.
Within each management section of roadway, one or 11 survey units are inspected and rated to represent the condition of the entire management section. The percentages of distress observed in the survey area are extrapolated over the entire section ast, determine maintenance budgets. It is valuable to understand that not all distresses indicate similar failure or deterioration rates. If none or only one individual deduct value is greater than 2, the total value is used in place of the maximum CDV in determining the PCI; otherwise, the d66433 CDV is calculated as follows: For the example in Fig.
The entire management section is rarely rated completely. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. The backbone of any pavement management system is the measurement of the astm d 11 pavement conditions. Typical distresses are cracks, rutting, and weathering of the pavement surface. This portion of the collection is mainly automated as a collection process.
It is written as a guide and should be used as such. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

The PCI is a numerical indicator that rates the surface condition of the pavement. This also initiates development of performance curves used for prediction of future performance.
This portion of the collection is mainly automated as a collection process. Having the raters perform their observations in a controlled environment, versus working in aztm field along busy roadways, reduces the variances within the process.
In order to achieve a representative assessment of the 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. 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.
Auth with social network: D64333 Item s – proposed revisions of this standard. The total deduct value is obtained by adding the individual deduct values, that is, Determine q as the number of deducts with a value greater than 2.
L—Fine, longitudinal hairline cracks running parallel to each other with no, or only a few interconnecting cracks.
