Pavement Preservation Journal - Spring 2013 - (Page 25)

By Eric Thibodeau, P.E. I n an effort to bring pavement preservation (PP) practice to the attention of the motoring public and elected officials, the New Hampshire (NH) DOT conducted ceremonial ribbon cuttings for two pavement preservation projects in fall 2012. The ceremonies highlighted two of NH DOT’s PP techniques, asphalt rubber chip seal and micro surfacing, on two separate roads that were in good condition. The ceremonies were attended by DOT executives and personnel, elected officials, news media and industry representatives. NH DOT has developed an extensive strategy to preserve its 4,559-centerlinemile roadway network, valued in excess of $3.6 billion. Prior to 2005, most of the pavement maintenance work utilized hot-mix overlays, mill-and-fills, or rehabilitation/reconstruction. In most cases there were no planned strategies and most treatments were worst first. At ribbon cutting for New Hampshire 12 (Troy-Swanzey) micro surfacing on Oct. 5, 2012 are Rich Goodick, vice president-operations, and Elizabeth Wuori, president, Sealcoating, Inc.; New Hampshire St. Rep. Alfred ‘Gus’ Lerandeau; Alan Rawson, administrator, NH DOT Bureau of Materials & Research; Bill Cass, NH DOT Director of Project Development, NH DOT Commissioner Chris Clement, and Eric Thibodeau, chief, pavement management, and Chris Lanza, Construction Bureau, New Hampshire DOT ‘KEEP GOOD ROADS GOOD’ Pavement preservation treatments were utilized to a limited degree, but there was no formal program. With the use of a pavement management system and developing strategies, NH DOT has developed an extensive pavement preservation program by increasing its efforts to “keep good roads good” and minimize the need to spend large budget dollars doing rehabilitation and reconstruction. The PP program has been embraced not only by the pavement management group but also by NH DOT executives, including Commissioner Christopher Clement, as well as elected officials. Today, NH DOT is using field data, automated roughness and distress data collected annually, in-house analysis, and a well-designed pavement IDENTIFYING PAVEMENTS The first key is the identification process of selecting pavements in good condition, based on field data and timing of the planning of the treatment before the pavement falls below the good condition. The treatment alternatives are determined based on pavement condition, expected service life, desired surface characteristics, traffic volume and type, and pavement location within the state. The techniques are inclusive from crack sealing to CIR with an overlay. Originally in the development of the selection process, expected service life of various treatments were based on field experience, input from literature on various processes, other agencies experiences and contractor recommendations. Now, as NH DOT management program to develop and implement performance and costing data to aid in the decision process of selecting the right treatment for the right pavement at the right time—the definition of pavement preservation. This has resulted in a mix of fixes based on the existing pavement condition, expected outcome relative to performance and life extension, and cost-effectiveness. gains more experience with these treatments, the expected service life for each treatment is being determined for local conditions in the Granite State based on existing pavement, climate and traffic conditions. As a result, a system of Equivalent Annual Costs (EACs) has been developed for NH conditions based on field performance experience and data from various techniques. The data used are based on actual project costs and expected life for all the PP treatments used. Completed projects will continue to be monitored over time for treatment performance, treatment pricing will be updated as new projects are advertised, and expected service life and EACs adjusted accordingly. Pavement preservation now is embraced by DOT staff, management and elected officials in New Hampshire. Pavement preservation will continue to play an important role in spending the state’s limited budget dollars more wisely, and protecting previous infrastructure investments. Thibodeau is the pavement management chief for NH DOT and serves on the board of directors of the Northeast Pavement Preservation Partnership.
