PAVEMENT DESIGN METHODS: A LITERATURE SURVEY INTO LINEAR-ELASTIC THEORY AND CONDITION PREDICTION MODELS

This report presents the results of a literature survey into design methods for asphaltic pavements, discussing: 1) the applicability of the Linear Elastic Multilayer Theory (LEMT) in the calculation of pavement stresses and strains; and 2) condition prediction models for pavements, emphasizing on cracking and bearing capacity. It was written with a view to Dutch pavement design circumstances. Mechanistic design procedures are divided into response models and condition prediction models. The first predict the stresses and strains in a pavement as a result of a single load. The second predict the condition development of the pavement due to a repetition of such stresses, strains or loads. The predictions of the LEMT, which is used as the response model in Dutch design methods, are compared to various measurements. After a general review of condition prediction modelling, some models for cracking prediction are reviewed: a) visual condition index model; b) power model; c) sigmoidal model; d) lognormal probability of survival; e) Weibull probability of failure; and f) World Bank models for cracking initiation and progression. Two empirical models for bearing capacity are studied: a) one predicting development of the equivalent layer thickness; and b) one directly predicting deflection increase.
