Pavement Fatigue Degradation Phenomenon Assessment Based on Multi-load FWD Data and Stochastic Process Evaluation
On the example of the road pavement of a semi-rigid structure, this paper presents the concept of the parameters estimation of the experimental section tested after 30 years of use. In the context of the lack of technical history data of the analyzed road section, the resultant (conventional multilayer system, which is pavement and its subgrade) stiffness was analyzed in relation to the moment ...
متن کاملEvaluation of the Pavement Structural Condition at Network Level Using Falling Weight Deflectometer (fwd) Data
Large amounts of seal coats and thin overlays are applied every year by state highway agencies to improve the surface condition of pavements, but these measures have not successfully prevented the problem from reoccurring. As a result, the overall pavement condition keeps deteriorating because of the structural deformation of pavement layers and the subgrade. To make effective decisions about t...
متن کاملEmbedded Machine for Measuring Pavement Deflection Based on Lpc2214
In order to improve precision and efficiency of measuring pavement deflection in the transport area of China, a measuring machine based on embedded operating system μC/OS-II is designed with LPC2214 MCU. In the design, wireless communication technology, embedded technology, filter technology of software and hardware, anti-jamming technology and other advanced technologies are applied. The machi...
متن کاملStructural evaluation of rubblized concrete pavements in Iowa
Rubblization is one of the surface preparation techniques before placing a Hot Mix Asphalt (HMA) overlay that involves breaking the Portland Cement Concrete (PCC) pavement into pieces. This paper describes the structural assessment related to the long term performance of rubblized concrete pavements in Iowa. The structural performance of seven representative in-service rubblized concrete paveme...
متن کاملRunway Stiffness Evaluation Using an Artificial Neural Systems Approach
A critical issue concerning the deterioration of ageing road infrastructure all around the world is the need to rapidly and cost-effectively evaluate the present condition of pavement infrastructure. Non-Destructive Test (NDT) and evaluation methods are well-suited for characterizing materials and determining structural integrity of pavement systems. The Falling Weight Deflectometer (FWD) is a ...
