Foundation Design of Low Volume Roads: Evaluation and Performance
<p>A majority of roads in the state of SD are low volume roads (LVRs). The SDDOT has developed simplified methods for LVR pavement thickness selection. These guides allow users to obtain recommended asphalt surfacing and base course layer thickness based on the subgrade support and the average …

Hydraulic modeling and performance evaluation of low water crossings in Illinois
… are many old and aging bridges, culverts, and low water crossings on rural low-volume roads that need to be replaced. Low water crossings (LWCs) have been used as an economical alternative to culverts and bridges, designed without overtopping, on low-volume roads where there is a low number of …

Foundation for a national road prioritisation model for South Africa
… basic services; insufficient prioritisation of roads that best promote the general economy; an excessive rural road network; and application of inefficient road surfaces that increase road maintenance and road-user costs and fail to take advantage of the low shadow price of unskilled labour. The …

Artificial Intelligence and Spatial Modeling to Estimate Traffic Volume Measures on Local Roadways
… the variability and complexity of traffic flow on low-volume roads. To address this gap, the research develops and compares two modeling frameworks: a non-spatial Random Forest (RF) model and an enhanced spatial RF model. Using the comprehensive Statewide Traffic Monitoring Program (STMP) …

Development of a multivariate logistic model to predict bicycle route safety in urban areas
… operational and physical factors (traffic volume, lane width, population density, highway classification, the presence of vertical. grades, one-way streets and truck routes) to predict the severity of an injury that would result from a crash that occurred at a specific location. The rating …

Aggregate characteristics affecting response and performance of unsurfaced pavements on weak subgrades
"Design of low volume roads and unsurfaced pavements traditionally involves covering the prepared subgrade with an unbound aggregate layer of sufficient thickness such that traffic-induced wheel loads are adequately distributed and stresses on the subgrade can be tolerated. Aggregate gradation and …

Performance evaluation of unconventional aggregates from primary and recycled sources for construction platform and low volume road applications
… viable for the construction of unsurfaced and low volume roads. Although large-size unconventional virgin aggregates (also referred to as ‘rock cap’, ‘primary crusher run’ and ‘macadam stone base’) have been successfully used by several transportation agencies previously, performances of …
