Abstract:Recurring slope failures are common in Texas due to the extreme weather and soil conditions. TxDOT spends millions of dollars annually to repair embankment slope failures along state roads and highways. The proactive maintenance of highway embankments and cut slopes can significantly reduce the cost of emergency stabilization and improve highway operations. This project aims to develop a Slope Repair Maintenance and Management System (SRMMS) to identify the highly critical highway slopes to facilitate proactive slope maintenance. The objectives of this implementation project were to (1) collect data and create layers of an existing TxDOT ArcGIS database for assessing conditions of slopes and slope repairs, (2) develop slope failure predictive models, (3) monitor slope failures, calibrate slope failure predictive models, and update the location of critical segments of the corridors, (4) recommend rapid, resilient, and sustainable repair methods to prevent recurring failures, and (5) develop a repair and maintenance master plan. SRMMS will help TxDOT personnel identify critical slope segments and facilitate proactive slope maintenance decisions. The implementation of the system will minimize slope failures and enhance safety, road-user satisfaction, infrastructure service life, environmental sustainability, and transportation system reliability.
