Polyurethane plastic runway foundation construction specifications: 1. Ground (1) generally preferred soil compaction or compaction can be directly; (2) the sinking of a large and high water content, the plastic runway, was rubber-like soft soil must be replaced and reinforced, not as a group humus soil, should be replaced; (3) the frozen area, the surface should be below ground Icy line, plastic runway stadium construction to frost damage gum Schomburg plastic surface; ( 4) base soil is too dry or too wet or dried should be appropriate to add water to achieve the optimum moisture content was appropriate compaction; (5) with crushed gravel or brick for the foundation soil surface treatment, should adopt a particle size of 40- 60MM block of material, the indentation depth of not less than 40MM; (6) when the base soil, such as the need to replace, should be stratified, the thickness of each layer of the virtual shop equipment should be based on rolling performance, soil types, moisture content and construction The method of determining the actual situation; (7) to the longitudinal rolling from side to Rolling Road, the heavy rolling until smooth solid so far; quality standards (8) to the grassroots: A. After pressure rolling machine pressure, no significant wheel tracks, no weak from the skin, badminton courts plastic runway, no topsoil loose waves and other phenomena; B. Compaction density of not less than 95% Optimum compactness; C. Thickness tolerance + 10%; D. Aspect broken elevation tolerance + 2CM; E. Width of not less than the design width; construction plastic runway plastic runway construction requirements in asphalt or concrete foundation, basic practices and road construction about the same. Higher base surface flatness requirements to ensure consistency plastic surface layer thickness, elasticity uniform plastic stadium runway, on the basis of quality requirements are as follows: 1 slope: horizontal <1% (curve 8 ‰, straight 5 ‰, semicircular area 5 ‰), longitudinal <1 ‰, high jump area <0.4%, the surface should be flat, smooth, smooth drainage. 2. Flatness: Flatness pass rate above 95%, three meters straightedge error 3mm. 3, positioning: the exact construction and draw lines, need for strong distinctive markers mark the four semi-tangent points and two runway center site. 4. Drainage: drainage system is necessary in two hours after the rain water discharge. In the frozen area, between the asphalt layer and add a layer of gravel layer is preferably a cloth buffer layer. Drainage trench along the foundation should do special water treatment. 5, the strength and stability: the foundation should have a certain strength and stability, even a solid surface, no cracks, no bad side seams straight and smooth. Cushion compaction, density of greater than 95%, after the medium-sized rolling machine pressure, no significant wheel tracks, loose topsoil, waves and other phenomena.
