An asphalt emulsion is liquid asphalt cement emulsified in water. It is composed of asphalt, water and an emulsifying agent. The emulsifying agent is sometimes called the surfactant, which is composed of large molecules. These soap molecules are like tadpoles, having a hydrocarbon tail soluble in liquid asphalt and an electrically charged or ...
Mulch Tie Down. The emulsion may be used to anchor straw or hay mulch. First, the hay is spread at 3-4 tonnes per hectare, then a mixture of seed and fertilizer is sprayed. Lastly, around 0.5 Lt./m2 of the emulsion is sprayed. A second method involves blowing hay and spraying emulsion at the same time. Mulching applications and facts:
Bitumen Emulsion SS-1. General Description of Anionic Bitumen Emulsion SS-1.

The asphalt emulsion also tends to hold moisture in the soil, promoting rich and speedy growth. Emulsified asphalt can be used as a 'tie-down', spray-applied over straw and hay mulch, or placed in a single blended application together with the mulch. Seeding and mulching contractors for decades have found emulsified asphalt to be a superior ...
An application of asphalt emulsion or chemically modified asphalt, followed by a a layer of aggregate which is rolled and embedded into the emulsified asphalt. The process may be repeated to create a double or triple chip seal. Chip seals are used to prevent water intrusion into an pavement and create a high friction surface for safety.

CSS-1H is a slow-setting cationic asphalt emulsion that is designed for various paving and industrial uses. Asphalt emulsions are classified according to the electric charge that surrounds the emulsion's asphalt particles (i.e. whether it is a cationic or an anionic emulsion) and how quickly the suspended asphalt particles separate from the
The cost of the asphalt application was estimated at $600 ac -1, but a 1978 report from California put the cost at $880 ac -1 for the asphalt and $1,600 ac -1 including equipment and labor [1]. The comparable costs for wood fiber in that study were $144 ac -1 for product and $744 ac -1 including equipment and labor.
