Evaluating the Friction Characteristics of Pavement Surface for Major Arterial Road

Evaluation of Pavement Surface Friction Treatments

Measuring and Analyzing Pavement Texture Concrete Pavement Surface Characteristics Program

Introduction Pavement texture is defined by the irregularities on a pavement surface that deviate from an ideal, perfectly flat surface. As shown in Figure 1, the World Road Association (PIARC) has established standard categories of texture, classified by wavelength. These categories include microtexture (wavelengths up to 0.5 mm), macrotexture (0.5 to 50 mm), megatexture (50 to 500 mm), and ro...

Toughness Performance of Recycled Aggregates for use in Road Pavement

The policy of driving organization such as Highways Agency is towards the use of performance related specifications. This policy and adoption of European wide aggregate standards on the one hand, and sustainable construction pressures on the other, all strongly emphasize on further need for more developments to specifications and performance assessment methodologies inst...

Influence of the Road-surface Texture on the Speed Dependency of Tire/road Friction

Tire/wet road friction depends on two road-surface texture scales: the macrotexture (centimeterto millimeter dimensions) is responsible for the speed dependency of friction, and the microtexture (submillimeter dimensions) is responsible for the friction level at any speed. This paper deals firstly with the description of road-microtexture, the macrotexture scale being well documented. Consideri...
