Freezing prevention pavement using rubber powder

摘要

Here introduced is a newly developed freezing prevention pavement using rubber powder made from waste rubber. Freezing prevention pavement generally utilizes mechanisms and materials which have chemical and/or mechanical freezing prevention properties.rnFreezing prevention pavement is being used in several areas in Japan. However, due to its disadvantages, includingless durability and higher cost in comparison to regular pavement, few construction projects are employing this material. However, there is great demand for a cost-effective and serviceable freezing prevention pavement.rnIn light of this, we have developed freezing prevention pavement with higher durability and lower cost than existing freezing prevention pavement, using rubber powder. Here we report the results of laboratory confirmation testing of the temperature characteristics of the newly developed pavement, and of a follow-up survey of a trial construction project.
