Vertisols are clay soils that are common in the monsoonal and dry warm regions of the world. One of the characteristics of these soil types is to form deep cracks during periods of extended dry, resulting in significant variation of the soil and hydrologic properties. Understanding the influence of these varying soil properties on the hydrological behavior of the system is of considerable inter...

A model is presented for the fragmentation of drying soil, based on the geometry of two-dimensional crack growth. The model restricts itself to the formation of twodimensional cracks. The pertinent parameters used to generate cracking patterns include those used to characterise crack growth development as a random walk, fragmentation of peds above a certain size threshold and attraction of crac...

rangement and distribution of the cracks. Moreover, White (1972) explained the energy implications that The theory of water movement in high shrink/swell soils has expericause the cracks to reappear in the same position from enced consistent revision since Haines first presented the topic in 1923. Several aspects of the infiltration process in cracking soils have event to event. Johnston and Hi...

Fine-grained soils, in particular, expansive soils are prone to cracking. For these soils swelling-shrinking potential is quite high and hence they exhibit adverse affect on overall stability of geotechnical structures. This phenomenon may also be responsible for alteration of various engineering properties of soils such as hydraulic conductivity, water and leachate penetration, solute transpor...

A laboratory investigation on a scaled model of a landACT: l ti n a scaled o l f ­ fill liner was conducted to provide data regarding the occurrence l i e e and extent of desiccation cracking of prototype liners. The crack t t of desi t e li rs. intensity factor, CIF, was introduced as a descriptor of the extent of t f , , as i tr as f the extent of surficial cracking. CIF is defmed as the rati...

This study explored the feasibility of lignin based biofuel co-product (BCP) for subgrade soil stabilization, and more specifically, its impact on Hot-Mix Asphalt (HMA) pavement performance using the Mechanistic-Empirical Pavement Design Guide (MEPDG). The HMA pavement systems with BCP stabilized subgrade under different traffic and climate conditions were modeled using mechanistic based damage...

In another work, the “open safe” of the HAZUS-MH methodology was cracked to create seismic vulnerability functions that honor all HAZUS-MH methodologies and data, yet that appear in the form of tables of mean casualty rates (indoor deaths and injuries as four fractions of total occupancy) versus a structure-independent intensity measure, in particular, Sa 0.3 sec,5% or Sa 1.0 sec,5% . In this w...

The existence of specific expansive minerals in the clay soil related to the climatological conditions, seasonable variation of rainfall precipitation (wet and dry periods) and fluctuation of water table in Mediterranean countries, has resulted to induce unexpected shrinkage and swelling movements with all the unfavourable consequences. It was observed that light industrial structures and small...

Understanding of desiccation-induced cracking in soil has improved over the last 20–30 years through experimental studies, but progress predictive modelling desiccation been limited. The heterogeneous structure soils and multi-physics nature phenomenon, involving emergence propagation discontinuities, make mathematical description analysis a challenging task. authors present non-local hydro-mec...
