“…One potential choice is ABAQUS (Kim 2007;Leonardi 2014), which we will discuss in later sections. FEMs have successfully modeled not just the results of mechanical deformation and wear, such as from traffic, but also pavement degradation from thermal effects (Ban et al 2017).…”

The natural freezing and thawing of soils dramatically affects their thermal and mechanical properties. This can have destructive effects on structures built on those soils. This study developed a thermodynamic finite element model using multiple frost-susceptible soil types. It measured thermal conductivity and temperature through several freeze-thaw cycles. We identified moisture migration as likely the most significant factor in frost heave and frost penetration. Additionally, the thermal conductivity increased near the freezing front across all samples. For example, the thermal conductivity for ML (low-plasticity silt) soils rose from 301 to 357 milliBtu/(hr*ft*°F), which appeared to correspond to where the moisture concentrated and ice formation was highest. Our experimental results guided model development, where thermal parameters changed with respect to temperature, ice, and moisture during freeze-thaw cycles. Using dynamic thermal parameters improved frostdepth prediction compared to the standard Modified Berggren equation. For our tested conditions, the equation had an error of 2.2 in. for a frost depth of 8 in. while our model had an error of 1.4 in. These developments are important to airfield runway and general pavements design and maintenance in frost-affected regions. The findings will allow more accurate predictions of frost depth and deflection. DISCLAIMER: The contents of this report are not to be used for advertising, publication, or promotional purposes.

“…However, according to Rashadul Islam et al [ 7 ] and Rasol et al [ 8 ], existing pavements are no longer safe and comfortable, as they deteriorate over time, resulting in potholes, ruts, cracks, and other depressions. Similarly, Bevacqua et al [ 9 ] found that deterioration depends on water infiltration, weather conditions, repetitive traffic loading, stiffness gradients, construction problems, and the intrinsic and fracture properties of asphalt mixtures and pavement structures, which all clearly show the structural degradation of the pavement [ 4 , 7 , 8 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. This occurs because asphalt is a viscoelastic material and its behavior depends on temperature, i.e., the binder becomes viscous as temperature increases; otherwise, the asphalt turns brittle and susceptible to cracking [ 19 ].…”

Mode I fracture (tensile type) is the common cracking mode of asphalt pavements, which is caused by thermal cyclic loading or traffic. Some studies allow the analysis of the fracture modes by means of standardized tests, some of which are limited, difficult, with little repeatability or do not generate an adequate tension state. In this paper, mode I fracture toughness of asphalt mixtures with symmetric geometry specimens at intermediate temperature is evaluated. Experimental results from direct tension test and simulations on asphalt mix specimens subjected to intermediate temperatures of 10, 20 and 30 °C, mode I load rates (0.5, 1 and 2 mm/min) and notches (2 and 3 cm) were compared to find the variables that reflect the operating conditions of the asphalt mix. Results showed that shear stresses are 8.12% lower in the simulations with respect to the tests, while the load–deformation curves show 30% and 35% variation, where the temperature of 20 °C, the notch of 2 cm and the loading speed of 1 mm/min are the conditions that best represent the stress state of the test; moreover, it manages to consider the elastic and viscous components of the material.

Cracking of bituminous materials is one of the main distresses that results in roadway failure. As bituminous media are highly rate‐dependent at intermediate temperatures due to the viscoelastic nature of the binding materials, cracking is also highly rate‐dependent viscoelastic. This presents a clear need to address the phenomenon in the modeling‐analysis process for a more accurate design of mixtures and pavements. This study proposes an advanced computational modeling method to predict complex rate‐dependent cracking in bituminous materials and pavements. In particular, we explored an extrinsic nonlinear viscoelastic cohesive zone (NVCZ) integrated with Gaussian damage evolution. To examine the modeling method and its validity, two modeling efforts in multiple length scales were made: mm‐scale material‐level modeling and cm‐m scale hierarchical modeling that linked the mixture with pavement structure. The NVCZ modeling with Gaussian damage evolution successfully predicted material cracking and damage at different loading rates by using a single set of fracture parameters. This implies that the complex cracking behavior of bituminous materials can be characterized by material‐specific fracture parameters that can be identified by a simple fracture test. The pavement modeling through a parametric analysis demonstrated the sensitivity and capability of the modeling to effectively capture the interrelated influence of several core design variables, such as traffic, material properties, and layer configurations, all of which affect pavement responses and damage evolution. The computational modeling presented in this study has the scientific rigor to predict nonlinear rate‐dependent viscoelastic fracture of bituminous materials and pavements with a good modeling efficiency by significantly reducing laboratory tests.
