What are the advantages and disadvantages of slurry seal and chip seal?
Chip seal is to use special equipment, namely synchronous chip seal vehicle, to spread crushed stone and bonding material (modified asphalt or modified emulsified asphalt) on the road surface simultaneously, and form a single layer of asphalt crushed stone wear layer through natural driving rolling. It is mainly used as the surface layer of the road surface, and can also be used for the surface layer of low-grade roads. The biggest advantage of synchronous chip seal technology is the synchronous spreading of bonding materials and stones, so that the high-temperature bonding material sprayed on the road surface can be instantly combined with the crushed stone without cooling, thereby ensuring a firm bond between the bonding material and the stone.
