(A) the basis of the acceptance of artificial turf
A, the basis of the general use of cast cement concrete or asphalt, with a certain strength and stability.
B, basis and not peeling or cracking caused by sand from freezing.
C, based flatness error is less than 3 m ruler 4mm, with a certain slope, typically 3-5%, in order to drain rain.
D, in the frozen area, freezing technique should be used, usually between the asphalt layer and add a layer of geotextile gravel layer to buffer the water trench along the foundation should do special aaaa waterproof.
E, the base surface to keep clean and dry, you should ensure that after completion of the asphalt base maintenance period of around 30 days, so that the asphalt surface of the low boiling ingredients evaporate, Paul aaa card-based surface layer has sufficient bond strength.
F, concrete foundation should have about 30 days maintenance period, a large area reserved for expansion joints to be considered, the surface layer should be smooth handling.
G, asphalt concrete foundation technical indicators
a, the base density of greater than 95% RCC
  b, graded gravel subgrade compaction density of 2.3kg/cm2 layer above the surface smooth, solid no sand nest, plum phenomenon.
c, asphalt surface layer should be no oil, no cracks, no pressure joints, no water blocking water phenomenon.
(B) Acceptance Program
a, first check the site flatness and slope correction for defective parts.
b, control data inspection and acceptance, completion data provided by the construction unit.
c, the preparation of the construction program, the audit report to the owners.
d, according to the amount of preparation materials engineering programs to ensure construction quality and duration.
e, clean up the site, laying of artificial turf on the need to clean up the site, remove oil, debris, dirt and other rubbish.
f, around the field should be kept clean, non-garbage admission.
g, for a long time to build the old venue, expansion joints must be cleaned, filled with the new material.
