Pouring a lot of material, asphalt pavement pouring glue emulsified asphalt modified asphalt emulsion asphalt modified asphalt as well as ordinary road asphalt solvent resin pouring material, etc.The fracture depends on what type of season what kind of road crack width, etc. to solve the problem.
The most commonly used asphalt pavement crack filling process is divided into non-Notch Pouring and Notch Pouring two types. Not slotted pouring operation of law is divided into hot and cold operation of law: thermal operation of law generally use ordinary hot asphalt or modified asphalt potting hot asphalt pavement cracks, the use of conventional hot asphalt, conventional hot asphalt at high temperatures , low softening point and prone to weeping vehicle was taken away phenomenon, low temperature asphalt will become brittle and easy to fall off; and the use of modified asphalt due to the viscosity and thermal properties of modified bitumen flowing permeability difference poured asphalt pavement cracks very small, so when the low temperature expansion of pavement cracks easily crack, patch short life. Cold operation method is potting liquid bitumen (emulsion) liquid polymer modified asphalt. Because the liquid polymer modified asphalt mixed with the solvent, so that low-temperature flowability is improved permeation properties of the asphalt, but the high temperature stability decreased elastic recovery properties. When the summer heat is taken away easily overflow pollution vehicles on the road, easily opened when the low temperature in winter.
Slot is optional pouring asphalt pouring glue for pavement cracks after notching perfusion fill seal, typically through a mechanical process for mandatory pavement cracks cut, so that the road widening cracks deepen and perfusion pouring glue for pavement cracks potting. Many cracks in the early stages there is no need to deal with slotted process (such as a new repair pavement cracks appeared, and crack width smaller, irregular cracks, etc.), most cracks are irregular cracks, and the main crack cracks and surrounded by tiny capillary cracks, this method due to the mechanical cutting of pavement cracks mandatory itself is secondary to irregular pavement cracks and small cracks and hairline cracks damage. After a year at both ends of pavement cracks extending new pavement cracks, pouring glue with aging, and the water surrounding the small crack crack crack had led to a road pavement crack into a two or even more than, likely to cause water seepage, slurry pump, bite edge (crack width after notching generally 1.5CM 1.8CM depth is generally beginning to decline pavement bearing capacity) pits and other pavement disease. (Due to the pavement after notching crack width depth increase, the use of potting high temperature is generally about 180 ��) use of materials also increased environmentally unfriendly consume large amounts of energy.
