The Environmental Conditioning System (ECS) was designed to evaluate the
water sensitivity of asphalt concrete mixtures. The ECS subjects asphalt concrete specimens to a series of conditioning cycles including water flow, elevated and/or lowered temperature, and repeated axial loading. The purpose of this research was to: (1) evaluate the ECS...
Asphalt concrete pavement is subjected to several damaging actions from traffic
loads, water (from precipitation and/or groundwater sources), and temperature. The
durability of the asphalt-aggregate mixture, its ability to withstand these damaging
actions for long periods, is a very important engineering property. While the durability
of the asphalt-aggregates mixture depends...

Successful small business management frequently depends on the manager’s knowledge in five key areas: profit planning, using financial statements, analyzing cash flow, maintaining a healthy financial structure, and the ability to control and plan for future capital needs.
Ground-based skidding may cause unacceptable damage to woodland soils when owners make no attempt to minimize the area covered with skid trails. As much as 40 percent of the area may be covered with skid trails during a single entry if you do not plan and mark them in advance.

Adequate soil moisture is one of the most important factors in tree growth and production. The amount of irrigation needed varies greatly according to soil type and depth, season, weather, and tree size.
Aerosol concentrations and 3-D winds were measured from 9 to 25 September 2007, above a pine forest in California. The measurements were combined using the eddy covariance (EC) technique to determine aerosol eddy fluxes as a function of particle diameter within the accumulation mode size range (0.25 μm≤D[subscript]p≤1 μm here)....
