“…Even though the use of more technologically advanced methods will be useful to avoid manual field work for faster and accurate results and also to eliminate different assessor perceptions, the methods used in this study were more appropriate and cost efficient. As argued by Maser (1996), the use of objective methods alone in assessing and rating of gravel roads is irrational because surface conditions change rapidly. Moreover, identifying surfaces distresses using high-tech equipment will be challenging and very expensive, because it will require the use of technologies with high image resolution.…”

“…Several studies have also attempted to objectively assess and rate surface condition on gravel roads, but found out that they require highly specialized experts, costly equipment and is time consuming (van der Gryp and van Zyl, 2007). Similarly, Maser (1996) argues that the use of objective methods alone in assessing and rating of gravel roads is irrational, because surface conditions change rapidly. Rainfall conditions, traffic volumes and maintenance activities have the ability to modify the characteristics of gravel road surface conditions within a short period of time (Huntington and Ksaibati, 2007).…”

The prioritization and improvement of rural road networks is important in developing countries in order to uplift the socioeconomic conditions experienced by communities. So far, limited information exists on the conditions of unpaved or gravels roads, particularly in rural areas and the associated implications to rural economies. The present study therefore used visual observations and field-based measurements to assess the physical, environmental and anthropogenic factors affecting Minor roads (R3), Collector roads (R4) and Local roads (R5) in four rural communities in the KwaZulu-Natal Province, South Africa. The function of these road classes is to provide access from homesteads to main roads that connect rural areas to towns. In this study, two classification methods were used to rate the severity and extent of each surface distress on each road class. Results indicate that there was more than one surface distresses identified and assessed on each road class within the selected communities. It was noted that all the road classes had moderate to severe surface distress, except for the R3 road class in Emazabekweni community, reflecting problems associated with poor drainage systems and maintenance. Visual observation and field-based methods are useful tools that can aid in identifying and assessing the physical conditions of unpaved roads, as well as possible environmental, physical and anthropogenic factors at interplay, especially in resource limited regions. This study recommended that road authorities should ensure that proper drainage systems should be well designed; constructed and maintained on all gravel roads in order to reduce surface deterioration associated with runoff.

“…GPR data is also collected from vehicular platforms. [77,109] utilized a van-mounted, air-horn antenna to collect GPR data for road evaluations. [131] illustrated how 3D LiDAR data of the pavement surface can be gathered at highway speeds from van-mounted equipment.…”

“…Although GPR is a successful tool for measuring the thickness of asphalt pavement [135], the inherent characteristics of Portland cement concrete (PCC) pavement do not yield similar results. PCC has higher moisture and salt contents resulting in RADAR attenuation [15,77]. Also, the similarity between the dielectric constants of PCC and base materials make distinguishing between the two layers difficult.…”

Introduction Evaluating the condition of transportation infrastructure is an expensive, labor intensive, and time consuming process. Many traditional road evaluation methods utilize measurements taken in situ along with visual examinations and interpretations. The measurement of damage and deterioration is often qualitative and limited to point observations. Remote sensing techniques offer nondestructive methods for road condition assessment with large spatial coverage. These tools provide an opportunity for frequent, comprehensive, and quantitative surveys of transportation infrastructure. Methods The goal of this paper is to provide a bridge between traditional procedures for road evaluation and remote sensing methodologies by creating a comprehensive reference for geotechnical engineers and remote sensing experts alike. Results A comprehensive literature review and survey of current techniques and research methods is provided to facilitate this bridge. A special emphasis is given to the E. Schnebele ( ) · G.
