摘要: |
In 1992 the Ontario Ministry of Transportation (MTO) developed a new, statistically based end result specification (ERS) for the acceptance of hot-mix asphalt. As part of the ERS phase-in plan for hot mix, the specification for pavement compaction was introduced to the industry with the intent for full implementation by 1995. The acceptance procedure employs a percent-within-limits specification using the lot mean and standard deviation to ensure that the desired compaction is achieved. Using a life-cycle cost analysis, the appropriate payment factors were calculated on the basis of the expected life of the final product. Operating characteristic curves were developed to analyze buyers' and sellers' risks and to evaluate the expected payment factors for the acceptance plan. Simulations were carried out to assess the effects of the proposed price adjustment system. The system provides a bonus for consistent compaction that exceeds a specified quality level and an adjustment in contract price for work that does not comply with the specification. |
