Basis of acceptance
A, the basis of the general cast cement concrete or asphalt, with a certain strength and stability.
B, the foundation can not produce cracks and peeling or arising from the frozen sand.
C, based flatness error of less than 3 m ruler 4mm, with a certain slope, typically 3-5%, in order to facilitate the drainage of rain.
D, in the frozen area, should be used antifreeze technology, artificial turf is generally between asphalt layer and add a layer of geotextile gravel layer to buffer the water trench along the foundation special waterproofing treatment should be done.
A construction organization design artificial turf
E, base surface should be kept clean and dry, you should ensure that after completion of 30 days around the asphalt-based maintenance period so that the asphalt surface of the low-boiling ingredients evaporate, ensuring the basis of the surface layer has sufficient bond strength.
F, the concrete foundation must have 30 days or so of the maintenance period, a large area reserved for the use of expansion joints need to be considered, the surface layer should be smooth handling.
G, asphalt concrete foundation technical indicators
a, the density of the base is greater than 95% of the rolling
b, graded gravel layer of subgrade compaction density of 2.3kg / cm2 or more, the surface smooth, solid no sand nest, plum phenomenon.
c, asphalt surface layer should be no oil, no cracks, no pressure vocational and technical seams, no water blocking water phenomenon.
