Prefabricated track pavement Process Description: safe, environmentally friendly, excellent weather resistance, economical and durable, multi-color effect. Easy to install, just use special adhesive that we provide support, in a small amount of human and mechanical conditions, Stones roll to the runway in dense, based on the installation complete in 24 hours after the runway is ready for normal use . And maintenance-free characteristics. Polyurethane plastic runway gravel layer (1) gravel layer thickness of 100-120MM, its particle diameter is generally in the range 25-65MM, but not more than 2/3 the thickness of the cushion, using hard and tough, abrasion resistance uniform crushed granite or limestone, soft or not mixed with stones. Gravel should be more water chestnut shape blocks, clean soilless, excluding weathering powder and other impurities. (2) beach gravel should be a virtual height on the bar, to avoid numerous experiences of finding up, virtual height compaction factor multiplied by the design thickness 1.30-1.40, have been flat paving gravel, to a uniform particle size distribution, thickness to be consistent, should be cut off before rolling traffic playground plastic runway, to keep clean; (3) after the first slow-fast rolling, rolling type to the first light after the principle of rolling wheel tracks should overlap plastic runway construction, since the road side began to move toward the center, the street should be carefully repeated rolling, avoid crowded stone outward movement, before rolling to the sprinkler about 3-4KG / square, first with 6-8 tons of stabilized gravel rolling machine rolling, rolling Zhaobu pressure were 2-3 times. When finished, switch to 10-12 tons Rolling machines continue rolling, with the press with the sprinkler, water no more than every 1KG / square. To use medium-sized rolling machine stable gravel shall be used "to reduce the rolling speed," ahead of watering and other measures to prevent excessive angular gravel damage, if found excessive formation of gravel and stone chips rounded, signifies "rolling over" should be dug through crushed gravel section, screen out small stone, adding new stone with angular, re-rolling. In the rolling process should always check and found uneven phenomenon, the height should be picking pine leveling plastic runway, arrived at the expense of loose gravel surface should add the same broken Shibu Ping after compaction; (4) comparing the gravel particles large, and surface gap is too large, it can sew holes and spread a layer of stone inlay, having a particle size may be 5-20MM. Flat seam stone should insert as gravel gap, should form a separate layer, rolling to the gravel and inserts sewn tightly bound material without rolling up printed compacted density of 2.2 t / sq; plastic runway project _ Camry sports (certified) _ Qingyuan plastic runway provided by the Dongguan City Camry sports facilities Engineering Limited.
