Performance-related properties of low-volume roads when stabilised with a sustainable anionic polyacrylamide: particle and specimen-levels study

International Journal on Road Materials and Pavement Design, 2020
This study has been undertaken to investigate the benefit of using a sustainable water-soluble anionic polyacrylamide on different properties of pavement surface materials for low-volume roads.

Financing Low-Volume Road Improvements

Transportation Research Record: Journal of the Transportation Research Board, 2011
Over the past 30 years the population of Washington County, Oregon, has doubled to more than 530,000 residents. With growth limited to the urban area, resources for urban roads mostly kept pace with population growth, but little funding was available for maintenance and improvement of rural local roads.

Low-Volume Road Bridge Alternative

Transportation Research Record: Journal of the Transportation Research Board, 2000
Recent reports indicate that a significant number of the nation’s bridges are either structurally deficient or functionally obsolete. A large number of these bridges are on the secondary road system and fall under the jurisdiction of county engineers with limited budgets and engineering staff.

Modeling Low-Volume Road Erosion

Transportation Research Record: Journal of the Transportation Research Board, 1999
Low-volume roads are recognized as one of the primary sources of sediment in many watersheds. The authors have carried out research on the details of the complex soil erosion processes occurring on low-volume roads for more than 10 years. An overview of their research summarizes the results of numerous past and ongoing field and computer modeling ...

Soil Stabilization in Low-Volume Roads

Transportation Research Record: Journal of the Transportation Research Board, 2011
Overwhelming evidence supports the importance of gravel roads. However, road agencies are increasingly faced with the necessity of relying on marginal materials in construction of low-volume roads. Use of these materials necessitates that stabilization be used to alter the engineering parameters to ensure that corrugation, erosion, rutting, poor pass ...

Matting Solutions for Low-Volume Roads

Transportation Research Record: Journal of the Transportation Research Board, 2011
An evaluation of 11 commercial roadway matting systems was conducted to determine their effectiveness in carrying heavy vehicle traffic over loose-sand subgrades. Three of the 11 matting systems were also evaluated under the same loading conditions over soft, fine-grained subgrades.

A Framework to Incorporate Safety Performance for Low Volume Roads in Pavement Management Systems

Moratuwa Engineering Research Conference, 2020
Low volume roads provide the connectivity between residential, agricultural areas and the national road network. Those are especially critical in rural areas to provide accessibility for the community to fulfill their social and economic needs.

Models of Operating Speeds for Low-Volume Roads

Transportation Research Record: Journal of the Transportation Research Board, 2011
Recent studies have documented a noticeable disparity between the speeds for which roads are designed and the actual operating speeds. An important reason for driving errors on two-lane rural roads is the misjudgment of the real course of the road by road users.

Pavement maintenance practices of low-volume roads and potential enhancement: the regional experience of Colorado pavement management system

International Journal of Pavement Engineering, 2019
Most transportation agencies employ low-cost surface treatments and light pavement rehabilitation as affordable maintenance strategies on Low-volume roads (LVRs).

Overlay Thickness Design for Low-Volume Roads

Transportation Research Record: Journal of the Transportation Research Board, 2015
Identifying the appropriate overlay thicknesses is critical to a local transportation agency's ability to maintain its pavement network. Local agencies often use empirical approaches for designing the overlay thickness for low-volume pavements. For example, overlay design for low-volume roads in Illinois is currently carried out using assumed layer ...
