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. Stefano September 29, Detailed project level analysis is required once a particular management section is selected for treatment.
Specific precautionary statements are given in Section astm d The PCI is a numerical indicator that rates the surface condition of the pavement. List the individual deduct values in descending order. Continuous monitoring of the PCI is used to establish the rate of pavement deterioration, which permits early atsm of major rehabilitation needs.
Once management sections are chosen for funding within a given year, the project level deals with technical management decisions for more detailed conditions and specific project conditions.
Typical distresses are cracks, rutting, and weathering of the pavement surface. Note 1-Aggregate obtained by this test method may be used for sieve analysis. For a six-lane roadway, typically the outside and inside lane of each direction are driven.
Values obtained from these deduct curves depend upon the density and severity of each distress. How to Measure—Alligator cracking is measured in square feet of surface area. Once management sections are chosen for funding within a given year, the project level deals with technical management decisions for more detailed conditions and specific project conditions.

The percentages of distress observed in the survey area astm d 11 extrapolated over the entire section x determine maintenance budgets. Grading designations are related to the average seven-day maximum pavement design temperature, and minimum pavement design temperature. The PCI provides a measure of the present 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.
Instructional Objectives n Need for condition surveys n Collection methodologies n Four basic types of condition. Each distress must correspond in type and severity to that described in Appendix X1Distress in Asphalt Pavements Nineteen distress types for asphalt-surfaced pavements are listed. The lanes driven during a collection period are chosen to represent the overall condition of the roadway, but may not include all lanes.
ASTM D – 18 Standard Practice for Roads and Parking Lots Pavement Condition Index Surveys
The question of which street sections need work, how aastm money is needed, when treatment is scheduled, and which needs should be funded are a few of the elements involved in the network-level. 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.
We believe it may be helpful to answer commonly asked questions about this astn system.
For example, each roadway or parking area is a separate branch. We often receive questions regarding the Pavement Condition Index PCI values we provide from our field data collection. You have successfully saved to your supplier list.
The entire management section is rarely rated completely.
PAVEMENT CONDITION INDEX
PCI road survey results. Monday, June 9, Asphalt Systems Inc. This portion of the collection is mainly automated as a collection process.

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. Historical Version s – view previous versions of standard. A section should have the same traffic volume and load intensity. The PCI cannot measure structural capacity, nor does it provide direct measurement of skid resistance or roughness.
