“…Michalowski, and Biswas and Ghosh demonstrated that reinforcement in the soil domain increases the rate of internal energy dissipation in the system, thus enhancing the bearing capacity of footings ( 17 , 19 ). Following the same concept, the current analysis attempts to capture the effect of geosynthetic reinforcement on the load-bearing capacity of rigid pavements.…”

“…It is worth noting that the theory of Meyerhof was primarily developed considering the foundation bed to be homogenous and unreinforced ( 16 ). After that, several bearing capacity theories addressing the effect of reinforcement in the foundation bed were reported in literature ( 17 – 19 ). Subsequently, it could be reasonable to broaden the bearing capacity theories proposed by earlier investigations for estimating the load-bearing capacity of rigid pavements placed on reinforced soil beds.…”

“…In most earlier studies, the ground surface was assumed to be horizontal ( 17 – 19 ). However, soil embankments are inevitable with the growing demand for transportation infrastructure projects such as dual carriageways and high-speed railways in the built-up areas ( 20 , 21 ).…”

This study investigates the ultimate load-bearing capacity of rigid two-way concrete pavements placed on conventional and reinforced soil embankments using upper-bound limit analysis (UBLA). In the presence of the median strip, upper-bound solutions of rigid pavements resting on reinforced embankments did not draw much attention from previous researchers. Therefore, a rigorous UBLA is performed, adopting the multi-block failure mechanism for the intended purpose. The true upper-bound solution is achieved by satisfying the conditions of geometric compatibility and kinematic admissibility. The effects of the proximity of dual carriageways and embankment slopes on the load-bearing capacity of pavements are expressed in relation to interaction factors. The critical spacing beyond which the proximity effect ceases to exist is estimated for different slope angles of the embankment. A parametric investigation is performed to understand the influence of various soil parameters, embankment geometry, and layers of reinforcement. A notable improvement in the performance of two closely spaced rigid pavements can be observed by providing additional layers of reinforcement. The current outcomes are sensible and match well with the existing investigations.

“…In the past three decades, geosynthetics have been extensively implemented all around the world for improving weak foundations, reinforcing critical slopes and retaining walls, coastal protection systems, and improving weak pavement layers, among many other applications ( 12, 17–20 ). Both woven and non-woven geotextiles have been widely used for reinforcement and hydraulic applications in pavement design ( 17 ).…”

The longevity and performance of a pavement section depend on the characteristics of the subgrade soil. A majority of the pavements in North Texas, U.S., are constructed on expansive soils. The deterioration of the pavement performance because of rutting, cracking, and differential heaving is a regular phenomenon in the regions predominantly distributed with expansive soils. The pavements, particularly those built for low-volume traffic conditions, experience distress because of the high swelling and shrinkage characteristics of the underlying problematic soils. Geosynthetics have been traditionally used to improve such poor subgrades because of their many benefits, such as ease of installation, and ample mechanical and hydraulic properties. In the last decade, a newly available wicking geotextile, with a moisture redistribution capacity, has been developed to improve the performance of pavements constructed over expansive and frozen soils. In this study, small-scale laboratory and full-scale field studies were conducted to comprehend the wicking ability of this innovative geotextile in an expansive soil environment. Full-scale test sections were constructed with reclaimed asphalt pavement aggregate and traditional crushed stone aggregates in the base layer near North Texas. Details of the construction and instrumentation procedure are discussed in this paper. A comparative study between the performance of the pavement sections subjected to traffic loads and moisture intrusion was also performed. Furthermore, the rutting life of the sections, estimated using a linear elastic model, was compared and validated using the in situ data. The observations during the initial phase indicated that the wicking geotextile has the potential to improve the long-term pavement performance.
