Winter construction process and precautions for rubber running track

The following is our summary of the winter construction process and precautions for the rubber running track.

1. Check the local weather forecast before construction and make a suitable construction plan;
2. Do the foundation moisture content test, and the foundation moisture content is less than 5% before construction;
3. Whether the site is based on cement or asphalt, the first test with a test paper moistened with PH5-6 water. If the PH value is between 6.8-7.8, it is a weak alkaline foundation. Use 3% dilute hydrochloric acid or oxalic acid to scrub the site, such as PH If the value is 7.8-10, use about 6% dilute hydrochloric acid or oxalic acid to scrub the site. If the PH value is greater than 10, the strong alkali is not suitable for construction, otherwise, the glue surface will be delamination due to alkali migration for a period of time;
4. The best construction conditions: the temperature is between 10℃-30℃ (note: there is snow all year round in the north, and the temperature below 5℃ is no longer suitable for construction! In winter in the southern and central regions, the temperature has the opportunity to Above 10℃, construction is still possible!), the humidity is between 30%-85%;
5. Goods storage environment: It is recommended to store in a ventilated and dry room with a temperature between 10-30℃;
