An Introduction to Asphalt Emulsions | Asphalt magazine

The asphalt particles are surrounded by the ionic charge, which causes the droplets to repel each other and stay suspended in the water. All asphalt emulsions are designed to eventually break, or revert to asphalt and water. Some emulsions break by chemically destabilizing the surfactant, others by a simple evaporation of the water.

Inherent Factors Affecting Soil Infiltration

May 01, 2012 · Dislodged soil particles fill in the surface pores, contributing to the development of a surface crust, which restricts the movement of water into the soil. Equipment use, especially on wet soils, and tillage can result in compaction. Compacted or impervious soil layers have less pore space, which restricts water movement through the soil profile.
