摘要：	A Maintenance Test Section Survey (MTSS) was conducted as part of a Peer State Review of the Texas Maintenance Program conducted October 57, 2010. The purpose of the MTSS was to conduct a field review of 34 highway test sections and obtain participants opinions about pavement, roadside, and maintenance conditions. The goal was to cross-reference or benchmark TxDOTs maintenance practices based on practices used by selected peer states. Representatives from six peer states (California, Georgia, Kansas, Missouri, North Carolina, and Washington) were invited to Austin to attend a 3-day Peer State Review of TxDOT Maintenance Practices Workshop and to participate in a field survey of a number of pre-selected one-mile roadway sections. It should be emphasized that the objective of the survey was not to evaluate and grade or score TxDOTs road network but rather to determine whether the selected roadway sections met acceptable standards of service as perceived by Directors of Maintenance or senior maintenance managers from the peer states. The pavement sections were selected such that the sample contained a wide range of conditions including Very Good (like new) to Very Poor (extensive cracking, rutting, and rough ride) and in immediate need of maintenance or rehabilitation. In addition to pavement conditions, the roadside and traffic marking maintenance conditions were evaluated by the researchers when making final section selection. It was also important to sample sections within each facility type; therefore, the sample contained sections from the interstate, national, and state systems as well as numerous Farm-to-Market roads. Two county roads were also included in the sample. The MTSS participants traveled in six vans, and rated the one-mile sections traveling at highway speeds over a four-hour period. The results were recorded by the participants on survey sheets handed in at the end of the Survey. The evaluation was based on a simple 1.0 (Well Below Expectations) to 5.0 (Well Above Expectations) scale for each category. These results of the peer state rating were compared to the Texas Maintenance Assessment Program (TxMAP) annual ratings for these sections and the ratings of other participants, grouped according to their background and experience in highway maintenance assessment.
