Background technology
Airfield runway or slideway are typically in runway or the envelope coating of the asphalt surface of slideway, for delaying pitch old
Change, the quality and appearance for keeping bituminous paving outstanding.Runway or slideway bituminous paving are a kind of typical matrix porosity knots
Structure, there are a large amount of connectivity gaps for road surface inside, form abundant draining network, due to its characteristics of macro-pore, rainwater or sundries
Long-term to corrode, road surface will appear different degrees of damage.Runway or slideway bituminous paving are laid with asphalt, from roadbed to
Last time is laid with base, face layer, water-proof tack coat, and using rubber asphalt synchronous surface dressing, pitch sprinkling amount is about face layer
1.5kg/m2.Water-proof tack coat can use one layer of envelope coating that the spraying of airfield runway glue is very thin.
In general, runway rubber is matrix with high temperature refinery pitch, the mixed rubber of addition mineral filler, heat and catalyst are sprayed onto
Tough and tensile, durable, flexible envelope coating is formed on bituminous paving.The layer has barrier properties, grease proofness, anti-chemical substance (winter
Airfield runway uses deicing salt, need to ensure that road surface is not damaged), non-skid property.
Patent CN200410070053.7 uses the elastic permeable road surface considered to be worth doing comprising waste polyurethane, patent
CN201010132668.3 proposes a kind of waterproof pavement structure.These prior arts generally use polyurethane or pitch as waterproof
Sealing.As organic material, kind substance all extremely with however the runway or slideway of machine factory are often subject to the rubber pulley told
Friction, solarization, unrestrained machine oil or fuel etc. require fireproof high.
