Title: Microstudding of road concrete
Inventor: MICHEL GUERIN GEORGES JOSEPH
IPC: E01C7/35
Filed: 1991-04-19
Abstract: Method for surface treatment of road covering concretes with a high calcium (limestone) proportion in order to give them a sufficient surface roughness lifetime. This treatment consists in a surface microstudding by stone gravel (grit) with a very high polishing resistance and high density or artificial gravel with the same qualities. The maximum size of the gravel is defined in order to avert the risk of vehicle windscreen breakage in the event of accidental detachment (debonding) of a piece of gravel. Bonding may be promoted by the use of doping solutions for a pretreatment of the gravel. The spreading of the gravel may be preceded by a sweeping/rippling process and should normally be followed by a protective concrete curing treatment which does not run the risk of disturbing the bonding of the gravel.

Patent FR-2673937-A1 (FR)
Inventor: CARPENTER HARRY W
IPC: C04B41/89
Filed: 1992-03-12
Abstract: Un composite comprenant une matière céramique (30) dans laquelle sont noyées des fibres céramiques d'armature (10) est renforcé et rendu tenace par un revêtement céramique multicouche (20) entourant chaque fibre (10). Les couches multiples du revêtement (20) ne sont pas liées les unes aux autres. Elles sont donc séparées les unes des autres en présence d'une fissure progressant dans la matrice céramique (30), ce qui permet aux fibres (10) de s'écarter de la matrice et évite leur rupture prématurée. Le choix des matières pour le revêtement (20) de la fibre n'est pas limité par des conditions d'établissement d'un type particulier de liaison chimique entre le revêtement (20) et la fibre (10). L'invention est fondée en revanche sur la tendance mécanique des couches multiples non liées dans le revêtement de la fibre (10) à se séparer pour favoriser le retrait de la fibre de la matrice dans le sillage d'une fissure en cours de progression.
