Pavement Management Information System (PMIS) Defined

The PMIS is an automated system for storing, retrieving, analyzing, and reporting pavement condition information. It can be used to retrieve and analyze pavement information to compare maintenance and rehabilitation treatment alternatives, monitor current pavement conditions, and estimate total pavement needs. Detailed descriptions of the PMIS are given in the electronic manual file for the Design Division's Pavement Management Information System (PMIS) User’s Manual.

Data Collected

PMIS contains pavement evaluation data on all major pavement types used in Texas, including asphalt surfaced pavement, continuously reinforced concrete pavement and jointed concrete pavement. These types of data include the following:

  • distress data—describes surface defects
  • ride quality data—measures pavement roughness
  • deflection data—measures the structural strength of the pavement section
  • skid resistance data—measures surface friction using the TxDOT Skid Truck.

Important Distress Data

Some of the most important data collected are visual distress and rutting data. This is basic information that management at the section level may use to determine pavement maintenance needs. Skid data, when applied in conjunction with accident studies, can also indicate maintenance priorities for needed spot work with maintenance forces. It can also give valuable information for developing the preventive maintenance program. The following table lists the visual distresses that are collected for the three basic pavement types.
