• Abstract:
  Maine has hundreds of miles of highway that were constructed of Portland Cement Concrete (PCC) ; roughly 5.5 to 6.0 m (18 to 20 ft) wide forty or more years ago. Since that time these same highways have ; been paved and widened to 6.7 or 7.3 m (22 or 24 ft) with hot bituminous pavements to accommodate ; increased traffic volumes and enhance roadway safety. Bituminous materials were used in place of ; concrete due to the ease of placement and price of material. ; PCC is a rigid pavement capable of supporting weight with little deflection. In contrast, hot bituminous ; pavement is flexible and will flex to distribute weight across the roadway. When the highway is expanded ; beyond the concrete slab, there is a sharp decrease of support for this bituminous pavement resulting in ; settlement over prolonged use. This settlement may also be compounded by poor drainage capabilities of ; the underlying soils causing the unsupported pavement to drop lower than the existing height of the ; concrete supported pavement. This creates a longitudinal crack aligning with the concrete slab edge about ; 0.3 to 1 m (1 to 3 ft) from the right edge of pavement. Pavement to the right of this crack deteriorates to ; the point where maintenance crews attempt to smooth it out with cold patch year after year. Paving over ; the entire roadway is an option but, due to reflective cracking, the edge of pavement begins to deteriorate ; within 2 or 3 years. ; It is the intent of this experimental project to explore various shoulder treatments to increase support of ; the extended roadway and hopefully decrease or eliminate deterioration of the shoulder pavement.
