Roads are extremely important to a country's socioeconomic growth. Pavement performance
depends on its ability to carry commercial traffic over its design life. During the construction …

One concern usually expressed about the implementation of Intelligent Compaction (IC),
especially in tandem with modulus-based spot tests, is the uncertainty in the depth of …

Nondestructive testing methods have been increasingly used to evaluate in situ layered
stiffness of pavement systems. However, different testing methods could yield considerable …

Experimental results from field and laboratory investigations using a ground-coupled ground
penetrating radar (GPR), dielectric measurement, magnetic imaging tomography (MIT) and …

The use of highly-polydisperse soil-rock mixtures (S-RM) as the main filling materials in civil
engineering is increasing. The rapid and accurate evaluation on the compaction densities of …

This paper presents a case study for constructing aggregate subgrade improvement (ASI)
layers using quarry by-product aggregates (QBA)—a quarry mix of large primary crushed …

An earth-rock dam is composed of multiple materials compacted by rollers with complex
operation modes, which can easily lead to the abnormal fluctuation of harmonic-ratio-based …

Intelligent compaction (IC) technologies have been used to locate and identify areas of soft,
weak or non-uniform subgrade support, which can be linked to pavement performance to set …

Abstract Quarry By-products (QB), usually less than 0.25 in.(6 mm) in size, are the residual
deposits from the production of required grades of aggregates and are often stockpiled in …

Texas Department of Transportation (TxDOT) current practice for field compaction quality
control and acceptance for base, subbase and soil layers is to determine the compacted …
