“…There are many factors that may affect the texture characteristics and friction variation of diamond grinding surface. The detailed information can be found elsewhere (Li, Harris, & Wells, 2016). Although a great degree of variability clearly existed in the friction measurements regardless of pavement type as shown in Figure 4.10, there is no doubt that diamond grinding can provide durable, sound surface friction for both concrete and asphalt pavements.…”

“…A linear relationship was derived from the characteristic values of the Base IMFs and the measured coefficient of friction. Li et al came to the same conclusions from a qualitative point of view [135]. In their study, they characterised different diamond-ground road surfaces using laser scanners and experimentally measured the corresponding tyre-road friction coefficient by locked wheel braking.…”

Abstract:In this paper, a review on road friction virtual sensing approaches is provided. In particular, this work attempts to address whether the road grip potential can be estimated accurately under regular driving conditions in which the vehicle responses remain within low longitudinal and lateral excitation levels. This review covers in detail the most relevant effect-based estimation methods; these are methods in which the road friction characteristics are inferred from the tyre responses: tyre slip, tyre vibration, and tyre noise. Slip-based approaches (longitudinal dynamics, lateral dynamics, and tyre self-alignment moment) are covered in the first part of the review, while low frequency and high frequency vibration-based works are presented in the following sections. Finally, a brief summary containing the main advantages and drawbacks derived from each estimation method and the future envisaged research lines are presented in the last sections of the paper.

“…This grinding technique is referred to as horizontal grinding as the grinding tools rotate in the horizontal plane. This shall not be confused with the much more common grinding technique, most often referred to as "diamond grinding", in which parallel "saw blades" rotate in the vertical plane (Gardziejczyk & Gierasimiuk, 2016;Li, Harris, & Wells, 2016;Sandberg & Mioduszewski, 2015). While both machine types use diamond tools, the horizontal type was used in this application to reduce macrotexture by "shaving off" the top of the texture, while the diamond grinding machines aim at reducing unevenness while simultaneously creating a longitudinal texture of narrow grooves.…”

A pavement surface having deflections from a plane mostly directed downwards in valleys is said to have a "negative texture", in contrast to a "positive texture" dominated by peaks. Negative textures are typical of porous asphalt pavements, but another way to achieve this feature is to grind off the peaks of the surface. This paper explores the effects of grinding off texture peaks in the horizontal plane on a number of Swedish asphalt pavements in order to reduce noise and rolling resistance. Noise measurements were made to evaluate the groundoff surfaces versus the original surfaces, and, in most cases, also rolling resistance, texture and friction were also evaluated. It was found that grinding led to a more negative texture, tyre/road noise reductions up to 3 dB and tyre/road rolling resistance reductions up to 15%. It is concluded that horizontal grinding provides a maintenance operation with a significant potential for reduction of noise and rolling resistance, without sacrificing friction, though with limited longevity.
