This study analyzes the role of vehicle speed and surface fines content on dust emission.
Accordingly, fifty unpaved road sections in Iowa were evaluated; surface loose-aggregate …

Granular roads are important to the economies of rural communities, as they provide access
to urban areas and comprise one of the main transportation systems for hauling agricultural …

In the current study, a mechanistic-based analysis was conducted to compare the
mechanical performance of granular roadway test sections built with three aggregate …

Poor subsurface drainage is frequently identified as a factor leading to the accelerated
damage of roadway systems. Geocomposite drainage layers offer an alternative to …

The freeze–thaw cycle is one of the major sources of damage to granular-surfaced
roadways, especially in areas where the timing of heavy agricultural traffic coincides with …

Unpaved roads in seasonal frost regions frequently experience severe damage during
spring thaws, which adversely affects traffic safety and significantly increases maintenance …

The goal of this project was to investigate the performance of granular road sections
stabilized with quarry fines byproducts and perform a benefit-cost analysis (BCA) to find the …

Granular surface roads in rural Iowa were frequently subjected to freeze-thaw cycle. Which
resulting road damage such as frost heave, frost boils, thaw weakening, rutting and …

Cyclical temperature changes occurring during seasonal freezing and thawing cycles
significantly impact the moisture content and matric suction of subgrade soils, contributing to …
