SAND-RESIN MORTAR FOR ROAD SURFACINGS

MORTIERS "SABLE-RESINE" POUR REVETEMENTS ROUTIERS

The addition of mineral fillers to thermostable polymers results in highly resistant and non-skid surface dressings. A laboratory study was conducted of synthetic mortar which could be moulded and be laid in-situ. Results showed that, at the present time, the only material which fulfilled the various criteria considered necessary, was epoxy resin. The use of other types of polymer, polyester, polyurethane and copolymers is fairly difficult, if not impossible, because of a fairly high sensitivity to water before or after polymerization of some of the ingredients of those types of resin. Satisfactory results are obtained with epoxy resin/quartz sand mixtures containing approximately 10% polymer in weight. Generally, these materials behave better than the best natural aggregates; they combine a high resilience with a satisfactory resistance to wear in the presence of water. The latter characteristic (which depends on the intrinsic properties of each ingredient and on the physico-chemical characteristics of the polymer/mineral bond) seems to be the most difficult to achieve. To complete the laboratory study, small-scale experimental sections were built on various types of support in order to check whether the manufacture of the surfacing could be carried out in-situ, and to control the behaviour of these new materials when subjected to traffic: after two or three years of traffic, these mortars are still in place and some are in a very satisfactory condition. /TRRL/
