Pavement Guide for Trimble Unity Maintain Introduction
Trimble Unity Maintain Pavement is a set of Pavement Management System (PMS) functions in Trimble Unity Maintain designed to help users manage their pavement network effectively. It stores, retrieves, and processes pavement-related condition and inventory data, and analyzes the current condition, future performance, and expected financial needs of the network.
The system allows users to easily view their inventory as well as its attributes history. It also enables users to perform analysis on the inventory such as:
- What pavement sections do I have?
- What attributes do my pavement sections have?
- What is the construction history of my pavement sections?
- What is the condition and trend of the network?
- How much will it cost to maintain or improve the network conditions?
- What is the best set of treatments?
- How do the various strategies compare to one another?
There are two version of Trimble Unity Maintain Pavement:
- Non-LRS version: Pavement data is modeled based on a segment inventory. Every pavement record in the system is linked back to a segment in the segment inventory.
- LRS version: Pavement data is modeled using a Linear Referencing System (LRS). Each pavement record in the system has its own location on the LRS network, indicated by Route, FromMeasure and ToMeasure.
Pavement is comprised of two major components: configuring the mapping between database tables and importing/exporting between Trimble Unity Maintain and Pavement.
Trimble Unity Pavement is a Trimble Unity Maintain app designed for organizations that use PAVER, a program for pavement management created by the U.S. Army Construction Engineering Research Laboratories (USACERL). Trimble Unity Maintain provides the work management system and access to the geodatabase through the Pavement app.
Designed to fully leverage the GIS investment, Pavement eliminates the need for costly duplication of asset data. Pavement managers create and maintain pavement (asset) inventory in the geodatabase, rather than building a database as tabular entries and shape files with unique identifiers in Pavement. Pavement inventory is managed within the geodatabase and exported to Pavement via Trimble Unity Maintain, which links the geodatabase fields to corresponding fields in Pavement.
The geodatabase serves as the central asset repository open to multiple applications, thereby promoting a truly enterprise-wide solution. Pavement also provides a communication link between Trimble Unity Maintain and PAVER to pass information back and forth between the two programs. Sharing data, such as pavement inventory, work orders, and inspections, increases the overall efficiency by utilizing the strengths of both Trimble Unity Maintain and Pavement.
Pavement inventory, work activities, and inspections are established and maintained in Trimble Unity Maintain. This information is exported to Pavement to calculate the PCI (Pavement Condition Index), perform pavement analysis, and utilize past pavement work histories to predict future pavement conditions. Pavement is also of significant value in planning pavement maintenance and rehabilitation (M&R) because it can set priorities of work to be done according to pavement condition and/or limit the work to a budgeted amount and available resources. This information can be used to schedule and track the recommended work activities. PCI, last construction date, and current surface type can also be imported into the geodatabase and symbolized on the map.
