①。Disfigurement there should be no air bubble, cranny or bed appeared on the court
②flatness on the any position of the ground track field, the beeline within 4m can’t exceed 6mm part depressing or within 1m can’t exceed 3mm part depressing, the jointing height of protruding and concave can’t exceed 1mm of each layer.
③Thickness the average thickness should be at least 12mm, the total layer runway of 10mm and 10.5mm should be no more than 5% total area of ground track field
④Concussion absorbing when compared with hard ground at 10-40 ℃,the attenuation of concussion should be at 35％－50％

The draining system should expel from the hydrocele after heavy rain within two hours time
※maintaining period
the maintaining period should be 28 days
②the chart for cement base
the quality requirements of cement base
※unknit degree
The unknit should measure up 95%, the error of 5-meter-ruler is 3mm.
※gradient curve path 8‰，straight path 5‰，half round section 5‰，the surface should be smooth enough for the drainning
※intension and stability
The surface should be equally burly, unknit without crack, no sodden in cumulus, the joint should be smooth. The clip should be 6000mm×6000mm. there should be no obvious mark, no appear, no earth relaxing and wave after being pressed by the middle sized roller
※ waterproof layer
the new PVC adding waterproof film, the meet should be over 200mm, the edge surplus should be over 150mm
※maintaining period
the maintaining period should be 21 days
※orientation
On the demands of exact construction and line drawing, the four half round cut line and two circle centers should be marked by the steady and obvious symbol objects for the runway courts
eight. The maintenance and maintain of plastic runway layer
* It fits for the common short nail no more than 9mm, training shoe, rubber cloth shoe or the soft rubber shoe
* It’s only used for training or competition, no other usage.
* It’s forbidden for any vehicle riding, and it should avoid the acute concussion and friction of machine
* The edge should be protected carefully, there should be no change at will, if there’s any shatter it should be repaired immediately.
* It should avoid the organic impregnant or the chemistry goods.
* It should keep tidy and clean, it can be cleaned by water; if it’s smeary it can be cleaned by 10% ammonia or the scour for cleaning.
* When training, the people may separated averagely on each runway in order to avoid the odds of court.
* It’s forbidden for any stub, chutty or drinks that with sugar in.
