Pavement condition assessment is essential when developing road network maintenance programs. In practice, pavement sensing is to a large extent automated when regarding highway networks. Municipal roads, however, are predominantly surveyed manually due to the limited amount of expensive inspection vehicles. As part of a research project that proposes an omnipresent passenger vehicle network fo...

A pavement surface having its texture deflections mostly directed downwards is said to have a “negative texture” and is expected to result in positive tire/road noise and rolling resistance properties. Negative textures are typical of porous asphalt pavements, but another way to achieve this is to grind-off the top of the asperities of a rough-textured surface. This paper explores the applicati...

Longitudinally tined (LT) concrete pavement surfaces were shown to produce less noise than transversely tined (TT) ones, making them more desirable where traffic noise may be an issue, if the two textures are shown to have equivalent safety performance. The present effort focused on rural freeway crashes between 1991 and 1998. This guaranteed the presence of high speeds and absence of various f...

The surface layer of road pavement has a particular importance in relation to the satisfaction of the primary demands of locomotion, such as security and eco-compatibility. Among those pavement surface characteristics, the "texture" appears to be one of the most interesting with regard to the attainment of skid resistance. Specifications and regulations, providing a wide range of functional ind...

Conventional distress detection method which dealing with each image through single algorithm and under single scale with lower efficiency. A robust and high-efficiency model for segmentation and distress statistic of massive pavement images which based on multi-scale space is proposed in this paper. It based on the facts that: (1) the crack pixels in pavement images are darker than their surro...

Desert pavement is a distinctive feature widespread across arid lands of the world. It plays a dynamic role in geomorphic, hydrologic, and ecologic processes. Where desert pavement predominates, infiltration is limited and rainfall is delivered as runoff to nearby bare ground areas where shrubs cluster. Desert pavement surfaces may appear monotonously flat and barren, but we have found, instead...

Abstract The assessment of the texture airfield pavements, in addition to assessing their roughness, is a component broader concept anti-skid properties, which significantly affect safety air operations. roughness pavement directly affects adhesion aircraft tire pavement, and additionally effectiveness dynamic drainage water from pavement. current standard requirements terms pavements do not di...

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...
