在使用中,把石棉加到铺路沥青中具有显著的技术优点,超过常规产品。而且,在经济方面,加有石棉的铺路沥青混合料有较大的效益,坚固的介质和长期节约能显著地补偿较高的产品成本。这些结论,是加拿大Econosult(从Lavalin分出的一个工程咨询公司)公司为国际石棉协会进行关于石棉在沥青路面中的应用研究时得出的。在象加拿大这样有频繁循环的结冻和解冻伴随的很冷的冬天和很热的夏天的国家,
In use, the addition of asbestos to paving asphalt has significant technical advantages over conventional products. Moreover, economically, asbestos paving asphalt blends have greater benefits, and robust media and long-term savings can significantly offset higher product costs. These conclusions came as a result of a study by the International Association of Asbestos on Asbestos Applications in Asphalt Pavement by Econosult of Canada, an engineering consultancy firm from Lavalin. In countries like Canada that have frequent cycles of freezing and thawing accompanied by very cold winters and very hot summers,
