Environmental Requirements For Plastic Runway During Construction

Many campuses choose winter and summer vacations when they transform their playgrounds into plastic runways, but some companies say they cannot build them. So, does this kind of construction still need to pick time? Next, let's take a look.

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 should be less than 5% before construction.

3. Regardless of whether the site is cement or asphalt foundation, first test with a test paper moistened with PH5-6 water. If the PH value is between 6.8-7.8, it is a weakly alkaline foundation. Wash the site with 3% dilute hydrochloric acid or oxalic acid, such as PH If the value is 7.8-10, wash the site with dilute hydrochloric acid or oxalic acid of about 6%. If the PH value is greater than 10, the strong alkali is not suitable for construction. Otherwise, the glue surface will delaminate 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 south and central regions, the temperature will have a chance to change after noon during the day. Above 10℃, construction is still possible!), the humidity is between 30%-85%.

5. Storage environment: It is recommended to store in a ventilated and dry room with a temperature between 10-30℃.

The above is the main content of the environmental requirements of the plastic runway during construction.
