Analysis and Evaluation of Transverse-Cracked Semi-Rigid Base Asphalt Pavements Using FWD Data

11 May 2006-pp 1-6
TL;DR: Wang et al. as mentioned in this paper developed a 3D FEM to analyze dynamic response of the cracked asphalt pavement under FWD loading pulse, which indicated that different types of transverse cracks affect the structure performance of pavement differently.
Abstract: Transverse cracks are the main premature distress of semi-rigid base asphalt pavements in China, which come from semi-rigid base reflective crack or temperature shrinkage This paper develops a 3-D FEM to analyze dynamic response of the cracked asphalt pavement under FWD loading pulse The results indicate that different types of transverse cracks affect the structure performance of pavement differently A new parameter, Pavement Structure Condition Efficiency (PSC), is developed to distinguish the different type to the transverse crack conditions, which can be directly induced by the FWD deflection data These results will be useful to the rehabilitation of transverse cracked asphalt pavement

TL;DR: In this article, the authors used dynamic finite element method (FEM) model instead of continuum elastic layered system to simulate whole or broken semi-rigid base asphalt pavement response under falling weight deflectometer (FWD).
Abstract: This paper used dynamic finite element method (FEM) model instead of continuum elastic layered system to simulate whole or broken semi-rigid base asphalt pavement response under falling weight deflectometer (FWD). Calculating results indicated that the sublayer strength can be evaluated by special FWD deflection basin parameter. Subgrade modulus (Esg) can be well evaluated by Curvature Index CI7 and Shape Factor F8 and the estimated results were not affected by pavement structure cracking condition. Whether Esg greater than 170MPa or not is defined as pavement subgrade failure criteria. Curvature Index CI3 can use to indicate the semi-rigid base layer structural condition and its criteria is CI3 value greater than 60um. This method have been applied and validated successfully in Jialiu Expressway rehabilitation project in Shanghai. It can more precisely distinguish weak sections for pavement rehabilitation design.
