| 摘要： | Performance-based pavement marking maintenance contracts (PBPMMCs) are one of the latest mechanisms used to maintain adequate pavement marking performance levels. TxDOT has issued two PBPMMCs, but the effectiveness of these contracts as compared to other contracting mechanisms from a risk management, cost, performance, or safety perspective has not been evaluated. This project gathered information to evaluate the effectiveness of PBPMMCs by evaluating the delivered pavement marking performance, safety performance, potential cost savings, and the most suitable performance measures and measurement protocols for inclusion into the PBPMMCs. The evaluations found inconclusive evidence as to the benefit of the PBPMMC from a safety, marking performance, or cost-effectiveness standpoint. Recommendations are provided to improve future PBPMMCs. |
