1、 Emergency treatment of rubber pavement 1
. 
Rain: if there is an emergency of rain when laying the plastic runway, please stop mixing immediately and cover the motor, mixer and hopper with the prepared plastic film
. 
If there is mixed glue in the mixer, the glue should be poured into the hopper car immediately
. 
When the garbage is disposed of, the remaining glue should be quickly spread into the cavity in the paving process
. 
If the operator finds that there are still large areas of rubber particles that have not been spilled, stop spreading the glue immediately, and spray a layer of glue on the solidified glue surface the next day
.

.
Strong wind: in case of strong wind emergency during paving construction, please stop batching and paving immediately; If any debris is found scraped to the surface of glue or liquid, it shall be removed continuously; If debris is found blowing onto the glue during the process of spreading rubber particles, remove the debris first, and then sprinkle rubber particles
.

.
Power failure: if power failure occurs during batch processing, if the circuit can be repaired in time, it should be repaired immediately
.
If it cannot be repaired in time, please stop the batching immediately and inform the paving process to prepare for shutdown
.
If there is material in the mixer, it should be discarded
.
2、 Before construction, we need to check and accept the quality of asphalt concrete foundation
.
The acceptance standard shall be in accordance with the design standards and technical specifications
.
If the corresponding drainage facilities are provided, the plastic runway can be used all day
.
The ambient temperature of the site laying should be controlled at 5 ℃ ~ 38 ℃, avoid working below 5 ℃ and above 38 ℃, the relative humidity should be controlled below 70%, and the foundation should be level and clean
.
Adjust the amount of catalyst according to the temperature and relative humidity, and control the curing speed properly
.
When the color paste and prepolymer are stored, the barrel cover should be tightened
.
The water content should be tested before use
.
After testing, the water content in the foundation should be controlled to avoid bubbles after gluing
.
When the plastic paving material is out of factory, it is necessary to examine the quality inspection certificate and the validity period carefully
.
2
.
Nailing of formwork strip: nail the wooden formwork strip wrapped with polyethylene film along the drawn bottom line according to the predetermined area
.
The formwork strip shall be flat and fixed with anchor nails to prevent material leakage
.
3
.
Surveying and drawing the bottom line: in order to reasonably arrange the daily paving workload, it is necessary to measure and draw the dividing line according to the set plan, and then divide the whole track and field field into blocks, and then pave it
.
In order to ensure smooth drainage and less joints, the construction procedure of first inner ring and then outer ring is adopted
.
4
.
Preparation of finished products: calculate the required semi-finished products according to the paving area, hoist the required slurry and prepolymer to the operation platform respectively, and discharge them orderly according to the batch number, and put the required black rubber particles and catalyst on the appropriate position on the operation platform respectively
.
The above main introduction is the plastic surface pavement of plastic runway and construction precautions, hope to help you! Looking back in the past, is silicon Pu good for basketball court? You can understand the prefabricated plastic runway after one look! EPDM plastic runway construction technology and requirements.
