Interstate Pavement Condition Sampling General Interest: provides practical guidance to engineers responsible for the day-to-day design, construction, rehabilitation, maintenance, and management of pavements.

Primary Topic: Pavement Management

Description: With the passing of the Moving Ahead for Progress in the 21st Century Act (MAP-21), the Federal Highway Administration (FHWA) has proposed that the Highway Performance Monitoring System (HPMS) data set is the data source for the national pavement performance measures. The objectives of this project are to: 1. Collect an unbiased baseline study of a statistically significant sample of the entire Interstate Highway System (IHS) and produce a report indicating the pavement condition on the IHS nationally and in each State where data were collected. 2. Determine if HPMS is an unbiased representation of the pavement condition of the IHS. 3. Recommend improvements to HPMS data collection and reporting that are necessary to either make HPMS unbiased or improve its precision, in regard to performance management and FHWA's use of HPMS data.

The project answers the following questions regarding HPMS data collection: Is two-way data collection necessary? Does data need to be collected in more than one lane in a direction? What is the optimum HPMS section length? Do all distress items require full extent reporting or is sampling adequate? Are protocols proposed by FHWA adequate for collecting and reporting distress or do they need improvement? This report documents the entire research effort, with particular emphasis on the data collection and data analyses activities.
