Development of Economical Low‐Volume Road Bridges

Journal of Structural Engineering, 1988
Low‐volume road bridges are currently designed according to the same specifications as urban highway bridges. Thus, many of the low‐volume bridge designs are overly conservative and uneconomical. This paper addresses this issue and proposes modifications of the existing specifications in the area of fatigue, deflection, allowable stress, composite ...

Enzyme Stabilization of Low-Volume Gravel Roads

Transportation Research Record: Journal of the Transportation Research Board, 2015
The purpose of this research was to investigate the efficacy of enzyme stabilization on unpaved, low-volume roads through formal field experimentation with a control section. An experimental site was divided into six lanes for treatment with water only, portland cement, a combination of portland cement and Enzyme A, Enzyme A only, Enzyme B only, and a

Low-Volume Roads with Neat Sand Bases

Transportation Research Record: Journal of the Transportation Research Board, 2015
Vast areas of Southern Africa are covered with surficial sands of Tertiary to Quaternary age. These consist of aeolian sands that are widespread in the western areas of South Africa, Namibia, Botswana, Zimbabwe, and Angola and reach as far north as the Democratic Republic of Congo, as well as coastal and alluvial sands more prevalent in the eastern ...

Materials for Sealed Low-Volume Roads

Transportation Research Record: Journal of the Transportation Research Board, 1999
Many unsealed roads carry relatively high traffic, which results in excessive maintenance requirements and costs. Sealing of these roads with a bituminous surfacing is typically cost-effective if minimal upgrading of the existing road needs to be done.

Applying Large-Scale Optimization to Evaluate Pavement Maintenance Alternatives for Low-Volume Roads using Genetic Algorithms

Transportation Research Record, 2018
Over the last decade, significant progress has been made to customize the maintenance policies of low-volume roads (LVRs) to local needs and available resources.

MGEOT: A low-volume road designer

Geotextiles and Geomembranes, 1993
Abstract A calculation program is described to design geotextiles in low-volume roads of soft subsoil. The theory is based on membrane action. The program specifies the required quality of the geotextile as a function of the acceptable rut depth.

Pavement Maintenance Management System for Low Volume Roads in Sri Lanka

Moratuwa Engineering Research Conference, 2019
In Sri Lanka there are about 150,000 km of roads and among those about 75% are considered as rural low volume roads [1]. These roads are essential in community development, transport of people, goods and services in the rural areas.

Asset Valuation of Low-Volume Road Networks

Transportation Research Record: Journal of the Transportation Research Board, 2007
Asset management is a systematic process of maintenance, modernization, and operation of infrastructure assets in an economically efficient way. For these reasons, asset management has been considered as an emerging concept applied in the area of transport management. Many countries have developed procedures to evaluate pavement infrastructure assets;
