Low-Cost Pavement Systems

This report presents the benefits of low-cost pavements to agencies and their challenges, based on real-life examples. It offers a methodology that can be adapted by the user to specific conditions or used as is with the suggested parameters. Low-Cost Pavement Systems are defined as infrastructure solutions for road surfaces designed to minimize initial construction expenses and ongoing maintenance costs while ensuring adequate performance and durability. A Low-Cost Pavement System should ensure [...]

Super-Single Tires Configuration Overview

Development of road freight transport is led by economic growth and efficiency. The impact of road freight on infrastructure is very important for road authorities. Physically, the impact on pavement is directly linked to the pressure exerted by vehicle loads, which highly depends on global vehicle weight but also on tires configuration. Looking for more cost-efficient transport, hauliers are looking for trucks that have lower maintenance costs with higher loading capacity. To address this demand, [...]

Disaster Management and Recovery Techniques for Road Administrators - Technical Report

Road networks are one of the most important infrastructure elements that support all kinds of socio-economic activities. In the case of disasters, the role of a road network is more crucial. The purpose of road disaster management is to increase resilience of road networks, effectively and efficiently. Resilience of road networks include not only resilience of the network itself (e.g., planning and construction of alternative road network or alternative transportation) but resilience of road facilities [...]

Models for Sight Distance in Road Design - A Worldwide Comparison of Standards - A PIARC Technical Report

This report is the second of two planned publications of PIARC Task Force 4.1 “Road Design Standards” in the period 2020 – 2023. PIARC considered the importance of comparing international road design standards to check their updated status and the degree of their readiness to face the forthcoming innovations in road mobility. The full report presents a review of selected models in the field of road design standards based on a literature review, which was the first publication of PIARC TASK [...]

Measures for improving resilience of pavements - Technical Report

This report discusses resilience in pavements with regard to various vulnerability issues resulting from disruptions or hazards due to climate change, vehicular traffic, and natural and human-caused disasters. For the purpose of this report, resilience is approached from a “bottom up” or object level perspective. The possible impacts of the three categories of pavement stressors mentioned above—climate change, vehicular traffic, and natural and human-caused disasters—are described. Several [...]
