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.
