Nuclear density gauges (NDG) have been widely used for field compaction control. However, their shortcomings include the burden of licensing with nuclear regulatory agencies, gauge maintenance, storage and transportation restrictions, requirement to

When subjected to ambient daily temperature fluctuations, a 109.5 ft-long geosynthetic reinforced soil integrated bridge system (GRS-IBS) was observed to undergo cyclic straining of the superstructure. The upper and lower reaches of the superstructur

A 109.5-Ft-long Geosynthetic Reinforced Soil Integrated Bridge System (GRS-IBS) in Hawaii was instrumented to measure superstructure strains, vertical pressures below the footing, lateral pressures behind the end wall and modular block facing, and la

Obtaining the particle size distribution (PSD) of fine-grained soils in hydrometer testing has several shortcomings, particularly long test duration, whereas a laser diffractometer can provide a soil’s PSD relatively expediently. PSDs of the finer

A power model (e = A. NB) to estimate permanent strain (e) from single-stage repeated load triaxial (RLT) tests can simulate both shakedown and incremental collapse. When the exponent B 1, the same plot concaves upwards, mimicking that of a material

The scour rate found by the cohesive soil-erosion function apparatus (SRICOS-EFA) method provides more accurate and realistic scour predictions than the Richardson and Davis equation, which tends to overpredict scour, especially in cohesive soils. Sc

Nearly 60% of bridge failures in the United States are caused by scour. When water flows in a channel, there is a critical value of riverbed shear stress; below this value, scour will not take place. This critical shear stress is an important paramet

Scour and Erosion.
The pocket erodometer test (PET) is an inexpensive and expedient way to derive the erosion categories of soils. The test involves impinging a regulated jet of water at the end of an undisturbed soil sample and measuring the depth of scoured hole afte

Crushed recycled concrete aggregate (RCA) has been widely utilized as base and sub-base course and as backfill. Despite the advantages of RCA, one of the potential concerns in some states is that its use can lead to the precipitation of calcium carbo

The pressure for pavement and geotechnical engineers to incorporate sustainability into engineering projects has led to a rise in the use of recycled concrete aggregate (RCA) as fill and in pavement sublayers. Although the use of RCA has many economi
