Classification of the Acoustics of Loose Gravel [PDF]
Sensors, 2021 Road condition evaluation is a critical part of gravel road maintenance. One of the assessed parameters is the amount of loose gravel, as this determines the driving quality and safety. Loose gravel can cause tires to slip and the driver to lose control. An expert assesses the road conditions subjectively by looking at images and notes.

Experimental Study of the Modulus of Deformation Determined by Static and Dynamic Plate Load Tests
The Baltic Journal of Road and Bridge Engineering, 2020 Soil, or soil structure modulus of deformation, is one of the main design parameters for road engineering and traffic infrastructure design of, for example, highways, railways, runways and embankments. It is also the main soil improvement criterion. When
