The new AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) performance predictions for the anticipated climatic and traffic conditions depend on the values of the numerous input parameters that characterize the pavement materials, layers, design features, and condition. This paper proposes comprehensive local sensitivity analyses (LSA) and global sensitivity analyses (GSA) methodologies...

The correlations between pavement texture and tire pressure with the actual tire-road contact area were first investigated according to static characteristics; on this basis, influence mechanisms of speed friction coefficient systematically explored from angle coupling system dynamics via self-developed dynamic testing tire-pavement friction. By integrating above factors, BP neural network meth...

ROSANNE is a collaborative project in the Seventh EU Framework Programme which aims at developing/harmonising measurement methods for skid resistance, noise emission and rolling resistance of road pavements as a preparation for standardization. To achieve this, the project will follow the recommendations of key predecessor projects as well as consider ongoing work in CEN and ISO. The project wi...

this paper is a case study of the cause of distress and evaltion of main runway (29 l-ll r) of mahrabad international airport in 1320 , this run way was built (1800 length & 60 width ) from pcc for small aircrafts. later on 1329 and 13 39 the length of this run way was inc reased to 3000 m and 4000m , respectedly was increased to 3000m and 4000m,respectedly .since 1320, this run wa y h a s bee ...

The Local Authority road networks commonly comprise roads of various functional characteristics and a variety of construction types. In this paper we investigate about the use of digital techniques to obtain field data to increase safety and reduce labour (cost) requirements using a semi-automated distress collection and measurement system. In particular, the proposed algorithm automatically de...
