Whether new utility lines are being installed or existing services are being rehabilitated or maintained, subsurface utility work frequently involves cutting...

This presentation is intended to expose DOT and Local Government staff to the mechanics and repair of slope failures, commonly referred to as landslides. While the presentation will heavily cover general and introductory information on slides, exposure to more detailed analysis and repair type concepts...

The Maintenance Decision Support System (MDSS) is a decision support tool that integrates relevant road weather forecasts, coded maintenance rules of practice, and maintenance resource data to provide winter maintenance managers with recommended road treatment strategies. This presentation will give...

This presentation will cover the 4 processes most commonly used in maintenance welding - stick, MIG, flux core & TIG - as well as welding metallurgy, industry terminology, and safety.

Highway engineers continue to look for a means to increase the service life of surface treatments and reduce complaints by highway users of loose chips from traditional chip seal projects. Microsurfacing/Slurry Seals have proven to provide better results. The mixture cures into a hardwearing, dense-graded...

Cold-in-place recycling (CIR) is the processing and treatment with bituminous and/or chemical additives of existing HMA pavements without heating to produce a restored, cold mix, pavement layer. A complement to the CIR process is cold central plan recycling (CCPR). CCPR allows a contractor to produce...

Hot-in-place recycling (HIP) is an efficient process used to repair and rehabilitate deteriorated bituminous streets and highways. What is hot-in-place recycling? Maintenance strategy Specialty equipment States using HIP Review of stabilizing agents Design Criteria Bidding tips Construction...
