Local calibration of JPCP transverse cracking and IRI models using maximum likelihood estimation

Journal of Road Engineering 2024年第4期4卷 433-445页

作者： Rahul raj Singh Syed Waqar Haider James Bryce Department of Civil and Environmental Engineering Michigan State UniversityEast LansingMI 48824USA Wadsworth Department of Civil and Environmental Engineering West Virginia UniversityMogantowWV 26506USA

The calibration of transfer functions is essential for accurate pavement performance predictions in the PavementME design. Several studies have used the least square approach to calibrate these transfer functions. Least square is a widely used simplistic approach based on certain assumptions. Literature shows that these least square approach assumptions may not apply to the non-normal distributions. This study introduces a new methodology for calibrating the transverse cracking and international roughness index(IRI) models in rigid pavements using maximum likelihood estimation(MLE). Synthetic data for transverse cracking, with and without variability, are generated to illustrate the applicability of MLE using different known probability distributions(exponential,gamma, log-normal, and negative binomial). The approach uses measured data from the michigan Department of Transportation's(MDOT) pavement management system(PMS) database for 70 jointed plain concrete pavement(JPCP) sections to calibrate and validate transfer functions. The MLE approach is combined with resampling techniques to improve the robustness of calibration coefficients. The results show that the MLE transverse cracking model using the gamma distribution consistently outperforms the least square for synthetic and observed data. For observed data, MLE estimates of parameters produced lower SSE and bias than least squares(e.g., for the transverse cracking model, the SSE values are 3.98 vs. 4.02, and the bias values are 0.00 and-0.41). Although negative binomial distribution is the most suitable fit for the IRI model for MLE, the least square results are slightly better than MLE. The bias values are-0.312 and 0.000 for the MLE and least square methods. Overall, the findings indicate that MLE is a robust method for calibration, especially for non-normally distributed data such as transverse cracking.

Condition indices for rigid pavements: A comparative analysis of state DOTs using michigan PMS data

Journal of Road Engineering 2024年第3期4卷 348-360页

Pavement infrastructure is vital in providing services and links between various sectors of society. Therefore, thepreservation and maintenance of these roads are critical to attaining a pavement network in good conditionthroughout its service life. Various performance indicators like the international roughness index (IRI), pavementcondition index (PCI), and present serviceability rating (PSR) have been used by the state department of transportation (DOT) and highway agencies for evaluating pavement surface conditions and planning future maintenance strategies. Limited data availability, multiple distresses depending on region, lack of correlation of thesecondition indices to maintenance strategies, and data collection limitations pose a challenge for applying theseindices to local conditions. This paper compares condition indices of different states for rigid pavements. Further,using a specific condition index for local conditions is also highlighted. For this purpose, five states and theircorresponding condition indices were evaluated and compared to the michigan DOT distress index (DI). Thesestates include Virginia, minnesota, North Dakota, Louisiana, and Oregon. The corresponding distresses of eachcondition index were converted to make them compatible with the MDOT DI. This study used the MDOT'spavement management system (PMS) database to evaluate each condition index for 433 rigid pavement *** distress index was plotted against MDOT DI and compared using a paired t-test. Results show that thecondition indices of Virginia and minnesota are comparable to DI in terms of the Spearman correlation value. Thet-test results show that except for Virgina, condition indices from other states statistically differ from ***, one can't use those directly for local conditions in michigan. This paper presents the evaluation anddata requirements for each condition index and its impact on selecting a maintenance treatment.

PURPOSE: To evaluate the benefit of pars plana vitrectomy (PPV) and removal of the internal limiting membrane (ILM) in eyes with diffuse diabetic macular edem a refractory to laser ***: Prospective, consecutive, interve ntional case series. METHODS: Diabetic patients with biomicroscopic, angiographi c, and tomographic evidence of diabetic macular edema persisting for at least 3 months after numerous sessions of macular photocoagulation were evaluated for in clusion. Patients with biomicroscopic evidence of epiretinal membrane or taut po sterior hyaloid, previous vitreoretinal surgery, or active proliferative diabeti c retinopathy were excluded. The main outcome measures were macular thickness, a s measured by optical coherence tomography (OCT) and visual acuity (VA). RESULTS : PPV with ILM removal was performed in 11 eyes of 10 patients (four men, six wo men; mean age=58.2 years). Six-month follow-up data were available for 10 eyes (91%). At 6 months postoperatively, central macular thickness had improved by at least 20%in eight of 11 eyes (mean preoperative thickness of 421 μm compare d with mean postoperative thickness of 188 μm; P=.007). Mean VA improved from 2 0/352 to 20/94 at 6 months (P=.002). By the most recent visit (range=6-20 month s postoperatively), VA had improved by at least 2 Snellen lines in 6 of 10 eyes treated with surgery alone. CONCLUSIONS: The early results of this ongoing study suggest that PPV with ILM removal may provide anatomic and visual benefit in so me eyes with chronic diabetic macular edema unresponsive or unamenable to additi onal laser photocoagulation.
