Models for Predicting Pavement Deterioration K. GEORGE, A. RAJAGOPAL, AND L. LIM The measurement and prediction of Models for pavement deterioration using LTPP book performance is a critical element of any pavement management system (PMS). Pavement condition rating (PCR), a composite statistic derived from functional and structural conditions, is used as a measure.
DEVELOPMENT OF PAVEMENT DETERIORATION PREDICTION MODELS GENERAL An important feature of a pavement management system is its ability to determine the current condition and to predict the future condition of the pavement network. Pavement deterioration models relate functions which are measures of distress to their causative factors.
As pavement condition grows to be one of the crucial problems facing our national highway system, a new challenge emerges in developing pavement deterioration prediction models that are reliable yet easily applicable by Highway Pavement Management System (HPMS) in State DOTS and other agencies.

Literature Review Pavement Deterioration PredictionAuthor: Nader Solatifar, S. Mohammad Lavasani. The CDOT pavement management software uses five distress indices to model pavement deterioration: three cracking indices (transverse, longitudinal, and fatigue), roughness, and rutting indices.
When all the values are loaded into the software, it generates deterioration curves for all roadway by: 5. Long-term pavement performance (LTPP) monitoring has been conducted in Australia for over 20 years. This research was funded by Austroads (representing federal, state and territory road agencies, local government and the New Zealand road agency) to promote improved practice and capability for the road by: 4.
The research objectives are to (1) evaluate and enhance asphalt pavement condition deterioration prediction models, (2) evaluate modulus backcalculation approaches for characterizing asphalt pavement layers of selected test sections, (3) develop three dimensional-finite element (3D-FE) asphalt pavement models and study impacts of cracking on.
BENCHMARKING PAVEMENT PERFORMANCE BETWEEN TRANSIT’S LTPP AND CAPTIF PROGRAMMES Table 1 Summary of results from this research. Hypothesis Outcome from this study Hypothesis 1: Three distinct stages of rut rate progression exist: • initial densification, • stable rut rate progression, and • failure and/or accelerated deterioration.
True. The LTPP database includes performance measures such as the International Roughness Index (IRI) and individual quantities of measured pavement distresses.
However, a performance measure based on these distresses, such as the PCI, is not part of the LTPP database and has not been fully developed to date. The paper investigates the applicability of IRI-based pavement deterioration prediction models, which include four deterministic models for pavement performance prediction (i.e., the NCHRP model.

A comprehensive, state-of-the-art resource on pavement design and materials. With innovations ranging from the advent of Superpave, the data generated by the Long-Term Pavement Performance (LTPP) project, to the recent release of the Mechanistic-Empirical Pavement Design Guide developed under NCHRP Study A, the field of pavement engineering is Cited by: Accurate pavement management systems are essential for states' Department Of Transportation and roadway agencies to plan for cost-effective maintenance and repair (M and R) strategies.
Pavement deterioration model is an imperative component of any pavement management system since the future budget and M and R plans would be developed based on the predicted pavement Cited by: 1.

Pavement condition data are collected by agencies to support pavement management system (PMS) for decision-making purpose as well as to construct performance model.
The cost of pavement data collection increases with the increase of survey frequencies. However, a lower monitoring frequency could lead to unreliable maintenance decisions. It is necessary to Author: Hui Wang, Zhoucong Xu, Lei Yue. Long-Term Pavement Performance Program, known as LTPP, is a research project supported by Federal Highway Administration (FHWA) to collect and analyze pavement data in the United States and Canada.
Currently, the LTPP acquires the largest road performance database. Short-term aging of asphalt binders is an inevitable phenomenon during mix production and laydown that significantly affects the rheological properties of asphalt binders and further contributes to the deterioration of pavement performance.
