摘要：	This project has demonstrated that it is possible to track the network-level performance of surface mixtures constructed in Texas. A procedure is outlined in the report to accomplish this and involves firstly identifying a projects extents in terms of Texas Reference Marker (TRM) information. A web-based tool was developed to allow TRM information to be derived for SiteManager projects constructed in Texas. This involves locating the beginning and ending points of a project as described in TxDOT SiteManager and/or Design and Construction Information System (DCIS) databases and interpolating the TRM information from a geographical database containing longitude and latitude coordinates of TRMs in Texas. The web-based tool provides street, topographical and satellite aerial maps to assist with the identification of the project extents. Once TRMs for a project are defined, network level performance indices and measures may be extracted for the project from the TxDOT Performance Management Information System (PMIS) database. The procedure as outlined is subject to certain constraints that are discussed in the report, most notably the assumption that the performance information as reported is for the asphalt mixture on the surface of the road being queried, which is not necessarily the case. / NOTE: Technical rept. / Supplementary Notes: Sponsored by Texas Dept. of Transportation, Austin.
