Available in PDF, EPUB and Kindle. Book excerpt: "The theory of viscoelasticity has been a classic topic, but its application to the modeling of flexible pavement has not been so successful even though viscoelasticity has long been characterized in asphalt concrete (AC). This is mainly owing to that the time-dependent property of a viscoelastic material is always very challenging and also that flexible pavement is a layered structure which further complicates the modeling work. This work establishes an efficient and accurate semianalytical solution for primary response (stresses, strains, and displacements) of flexible pavement on the ground of layered viscoelastic theory (LVET). Chapter I highlights the development of flexible pavement. On account of the viscoelastic AC, the theory of linear viscoelasticity is reformulated briefly from a mechanical standpoint. The material characterization and the constitutive equation for viscoelastic AC are reviewed. In Chapter II, pavement response to a moving load is expressed by the convolution integral of the pavement impulse response and the moving load. This convolution integral is elaborated, and in doing so the history of viscoelastic modeling of flexible pavement is reviewed and summarized. Pavement impulse response, the kernel of pavement response, is introduced in detail in Chapter III. Making use of the Prony series for a viscoelastic material, pavement impulse response is established numerically in the space domain and, for the first time, analytically in the time-domain. Such solution is called the semianalytical solution. To verify the semianalytical solution established in Chapter III, Chapter IV establishes the semianalytical solution for pavement response under the stationary load. This semianalytical solution is verified with a finite-element-based method through numerical examples, after which, the well-know collocation method is examined. Chapter V proposes the semianalytical solution for pavement response under moving dynamic load. The semianalytical solutions under various typical loading conditions are verified with the Abaqus solutions. Main conclusions are summarized in Chapter VI. Future works needed further research are suggested."--Abstract.

This book was released on 2009 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing interest for the use of mechanistic procedures and analytical methods in the design and evaluation of pavement structure rather than empirical design procedures. The mechanistic procedures rely on predicting pavement response under traffic and environmental loading (i.e., stress, strain, and deflection) and relating these responses to pavement field performance. A research program has been developed at the Center for Pavement and Transportation Technology (CPATT) test track to investigate the impact of traffic and environmental parameters on flexible pavement response. This unique facility, located in a climate with seasonal freeze/thaw events, is equipped with an internet accessible data acquisition system capable of reading and recording sensors using a high sampling rate. A series of controlled loading tests were performed to investigate pavement dynamic response due to various loading configurations. Environmental factors and pavement performance were monitored over a two-year period. Analyses were performed using the two dimensional program MichPave to predict pavement responses. The dynamic modulus test was chosen to determine viscoelastic properties of Hot Mix Asphalt (HMA) material. A three-step procedure was implemented to simplify the incorporation of laboratory determined viscoelastic properties of HMA into the finite element (FE) model. The FE model predictions were compared with field measured pavement response. Field test results showed that pavement fully recovers after each wheel pass. Wheel wander and asphalt mid-depth temperature changes were found to have significant impact on asphalt longitudinal strain. Wheel wander of 16 cm reduced asphalt longitudinal strains by 36 percent and daily temperature fluctuations can double the asphalt longitudinal strain. Results from laboratory dynamic modulus tests found that Hot Laid 3 (HL3) dynamic modulus is an exponential function of the test temperature when loading frequency is constant, and that the HL3 dynamic modulus is a non-linear function of the loading frequency when the test temperature is constant. Results from field controlled wheel load tests found that HL3 asphalt longitudinal strain is an exponential function of asphalt mid-depth temperature when the truck speed and wheel loading are constant. This indicated that the laboratory measured dynamic modulus is inversely proportional to the field measured asphalt longitudinal strain. Results from MichPave finite element program demonstrated that a good agreement between field measured asphalt longitudinal strain and MichPave prediction exists when field represented dynamic modulus is used as HMA properties. Results from environmental monitoring found that soil moisture content and subgrade resilient modulus changes in the pavement structure have a strong correlation and can be divided into three distinct Seasonal Zones. Temperature data showed that the pavement structure went through several freeze-thaw cycles during the winter months. Daily asphalt longitudinal strain fluctuations were found to be correlated with daily temperature changes and asphalt longitudinal strain fluctuations as high as 650 [mu]m/m were recorded. The accumulation of irrecoverable asphalt longitudinal strain was observed during spring and summer months and irrecoverable asphalt longitudinal strain as high as 2338 [mu]m/m was recorded.
