Soil Aggregates - an overview | ScienceDirect Topics

A soil aggregate is “a group of primary soil particles that cohere to each other more strongly than to other surrounding particles.” Soil aggregates form through the combined action of aggregation and fragmentation processes. That is, attractive and disruptive forces act on the particles in the soil to cause greater cohesion among some individual particles and groups of particles than others.

Leaching Characteristics of Recycled Asphalt Pavement: …

ABSTRACT: Reclaimed asphalt pavement (RAP) does not leach toxic materials into the ground and could be used as construction fill, according to a study conducted by University of Florida researchers. The study helps refute theories that RAP piles at asphalt plants pollute groundwater and gives contractors more options for using the material.
