This project is the extension of a Northland Advanced Transportation System Research Laboratory (NATSRL) FY09 project, titled as " Intelligent Pavement for Traffic Flow Detection " , which aims to explore a new approach in detecting vehicles on a roadway by making a roadway section as a traffic flow detector. Sections of a given roadway are paved with carbon-nanotube (CNT) enhanced pavement; th...

Abstract
 
 Inspection of the quality asphalt pavement layer is carried out by measuring dimensions pavement, namely length, width, and thickness, determining density layer. In implementation road construction or improvement, it often found that quantity mixture not in accordance with specifications used. Asphalt layers thickness according to standards tend reach design service life. ...

Large amounts of seal coats and thin overlays are applied every year by state highway agencies to improve the surface condition of pavements, but these measures have not successfully prevented the problem from reoccurring. As a result, the overall pavement condition keeps deteriorating because of the structural deformation of pavement layers and the subgrade. To make effective decisions about t...

This report discusses the implementation of a pavement condition rating (PCR) procedure to sample sections of the road network system. The resources needed are identified for such implementation. The uses of PCR data at the network and project level are also identified. The report stresses the development of a data base for integration of the various engineering systems for pavement management ...

This paper presents a model through which the cost associated with pavement warranty in performance based maintenance contracts are analyzed and quantified. Performance based maintenance contracts are eventually getting popular among the Highway agencies.These are long term pavement warranty contracts where the contractors are responsible for maintaining the pavement condition upto a certain sp...

In order to effectively prevent and control the rutting problem of asphalt pavement in deep loess area Eastern Gansu reduce road diseases, diatomite was added into mixture for laboratory tests. Through Marshall test test, optimum mix proportion mixture, optimal amount this were determined. The performance activated SBS is compared analyzed through tests on-site paving. results show that under s...

Incorporating Network Considerations into System-level Pavement Management Systems

Life Cycle Assessment (LCA) is recognized as one of the most comprehensive ways to evaluate the environmental impacts of different strategies associated with a physical feature such as highway pavement structures, bridges and vertical structures. Alternatively, life cycle cost analysis (LCCA) is performed by different agencies including Manitoba Infrastructure (MI) to select the most cost-effec...

This paper evaluates the importance of factors affecting commuter bicyclists’ route choices. Both route-level (e.g., travel time) and link-level (e.g., pavement quality) factors are examined. Empirical models are estimated using data from a stated preference survey conducted by the authors over the Internet. The models indicate that, for commuter bicyclists, travel time is the most important fa...
