Mo, L.T. Woldekidan, M.F. Faculty Civil Engineering and Geosciences Department Geoscience & Engineering Date 2010-08-04 Abstract By assignment of the Centre for Transport and Navigation (DVS) of the Dutch Ministry of Transport, Public Works and Water Management the Delft University of Technology developed LOT. LOT is a Lifetime Optimisation Tool for Porous Asphalt, PA, based on meso scale structural modelling. LOT sees an asphalt mixture as a structure and computes stress and strain throughout that structure as a function of mixture component behaviour, mixture geometry, and mixture loading. This paper discusses the validation of LOT on the basis of full scale ravelling test. Further validation is achieved by analysis of winter damage which developed in PA during the Dutch 2008/2009 winter. For this analysis LOT simulations considering Long Term Aged (LTA) PA at temperatures of -10° to +20°C were made. The paper comes to the conclusion that meso scale mechanical models allow ravelling performance based mechanistic design of high performance PA mixtures.
