Expansive clayey soils undergo significant volumetric changes, and desiccation cracks develop due to wetting and drying cycles. The presence of desiccation cracks changes the soil's hydro-mechanical properties and allows ...

The American Society of Civil Engineers ranks the existing pavement infrastructure in the USA at a sub-par ‘D’ grade. Population growth, fast-paced industrialisation and infrastructure ageing put significant strain on the ...

The quality and acceptability of the results of the spectral analysis of surface waves (SASW) field test are dependent upon the coherence function, in conjunction with the transfer function. The coherence value is a measure ...

Design of flexible pavements over fine-grained soils requires determination of subgrade resilient modulus over a wide range ofdegree of saturation and suction for different soils. A novel experimental setup was developed ...

The seismic response of a highly heterogeneous hydraulic fill dam was evaluated by studying the natural frequencies of the first and second modes of vibration and analyzing the crest accelerations of different two-dimensional ...

This paper presents a seismic slope stability assessment study of an inherently heterogeneous hydraulic fill dam in Texas. Extensive cone penetration soundings conducted at the dam site were interpreted to estimate different ...

A comprehensive investigation was designed and conducted to identify the potential causes of failure of a highway embankment slope in Texas and evaluate the effectiveness of lime treatment to rehabilitate the failed slope. ...

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 ...

The current pavement design guidelines, for example, Mechanistic-Empirical Pavement Design Guide (MEPDG), heavily rely on the resilient moduli of pavement materials. Some locally available pavement materials may not meet ...

Engineered cementitious composites are a class of high-performance fiber-reinforced cementitious composites with strain hardening and multiple cracking properties. The specialty of engineered cementitious composite is its ...
