Pavement Underdrain To Achieve Longer Life Pavement Structure, Tommy E. Nantung

Purdue Road School

Drainage as the key to pavement performance has been suggested since the early design of modern pavement structures. In fact, the three parameters for pavement performance are drainage, drainage and drainage. Drainage is so important to the performance of pavement that many state DOTs mandate a pavement underdrain system for routes with medium to high truck traffic. In the current evolution of pavement underdrain design, the speed of water removal from the soil foundation is the key issue. In a recent field investigation, some pavement sections with an underdrain system are not immune to pavement structural deterioration. It was determined …

Indygo Downtown Transit Center - Transforming Indianapolis, Ben Smith, Steve Robinson, Joe Fischer

This presentation will give an overview of the facility and then focus on attributes of the facility and of the design process that might offer useful lessons to other transit projects, including those of a smaller scale

Pavement Rehabilitation Options In Indiana, David Holtz, Tommy E. Nantung, Lisa A. Egler-Kellems

Purdue Road School

Many pavement rehabilitation options are now available to maintain the function and structure of a pavement section, and pavement engineers can choose an option that is suitable for the existing pavement condition. Many agencies today use traditional pavement rehabilitation techniques such as patching, overlay, and mill and fill. Recent developments in materials and construction have made available new rehabilitation options that are not only cost effective but also increase the use of recycled materials. This presentation will feature hot-in-place recycling, cold-in-place recycling, and full-depth reclamation techniques used successfully with recently rehabilitated pavement sections in Indiana.

Simplified Pavement Design For Lpas: Introduction To Pavexpress, Dudley Bonte

Purdue Road School

Simplified Pavement Design for LPA's; An introduction to and use of PaveXpress, a simplified, free, web-based pavement design scoping tool for roadway and parking lot pavements. The system was developed by Pavia Systems in partnership with the National Asphalt Pavement Association. PaveXpress creates technical sound pavement structural designs for flexible and rigid pavements based on widely accepted industry standards from the Association of State Highway Officials (AASHTO). The simplified pavement design system is based on empirical equation from the 1993 AASHTO Guide for the Design of Pavement Structures. PaveXpress is intended for use by local agencies, engineers and consultants …

Examining The Impact Of Pavement Rehabilitation Trigger Values And Annual Rehabilitation Funding On The Long-Term Network-Level Pavement Condition: A Case Study With The Indiana State Urban Road Network, Menna Noureldin, Jon D. Fricker, Kumares C. Sinha

Purdue Road School

Management of highway assets, including pavements, is immensely challenging in an era of uncertain funding for transportation agencies and higher service expectations from the public. Furthermore, the maintenance of pavement assets in good serviceable condition is one of the most cost-intensive operations for a highway agency.

Between 1996 and 2008, the Indiana DOT spending on improvement of pavement assets fluctuated between 35% and 50% of its asset management budget annually (Everett2012). Therefore, pavement managers are constantly exploring strategies to fulfill their mission of maintaining roads in good condition with the minimumbudget. Strategies may include examining the effectiveness of individual pavement …

Graphical Performance Measures For Practitioners To Triage Split Failure Trouble Calls, Richard S. Freije, Alexander M. Hainen, Amanda L. Stevens, Howell Li, W Benjamin Smith, Hayley Summers, Christopher M. Day, James R. Sturdevant, Darcy M. Bullock

Purdue Road School

Detector occupancy is commonly used to measure traffic signal performance. Despite improvements in controller computational power, there have been relatively few innovations in occupancy-based performance measures or integration with other data. This paper introduces and demonstrates the use of graphical performance measures based on detector occupancy ratios to verify potential split failures and other signal timing shortcomings reported to practitioners by the public. The proposed performance measures combine detector occupancy during the green phase, detector occupancy during the first five seconds of the red phase, and phase termination cause (gap out or force off). These are summarized by time of …

Road Safety Audits, Henry Brown

Purdue Road School

A Road Safety Audit (RSA) is a formal review of an existing or proposed road segment or intersection by an independent, multi-disciplinary team. The purpose of an RSA is to identify safety concerns and suggest possible countermeasures to the project owner. There are several benefits to conducting RSAs, including increased awareness of safety and a reduction in the number of crashes. The RSA process includes 8 steps during which the RSA team develops a list of findings and presents them to the project owner for consideration. The RSA process for an existing facility includes a field review during which the …
