METHOD OF TEST FOR SAND EQUIVALENT-Caltrans

Perform tests in groups of three, using working solution at different temperatures. Prepare solutions near the upper and lower expected temperature range and at approximately 10 ̊F increments through the range should be used. The temperature of the solution used with at least one group must be 72 ̊ ± 5 ̊F.

Asphalt Binder. The asphalt binder component of an asphalt pavement typically makes up about 5 to 6 percent of the total asphalt mixture, and coats and binds the aggregate particles together. Asphalt cement is used in hot mix asphalt. Liquid asphalt, which is asphalt cement dispersed in water with the aid of an emulsifying agent or solvent, is

Understanding Equivalent Pavement Designs

Determining the True Life-Cycle Cost of Pavements. Life‐cycle costs are an increasingly important decision point in the selection of pavement materials. Life‐cycle cost analysis (LCCA) requires careful consideration of the complete costs over time.

Aggregates for Concrete

CHAPTER 1—INTRODUCTION. Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete.

Sand equivalent test-Wikipedia

The sand equivalent test quantifies the relative abundance of sand versus clay in soil. It is measured by standardized test methods such as ASTM D2419, AASHTO T176, and EN 933-8. [1] The test is used to qualify aggregates for applications where sand is desirable but fines and dust are not. A higher sand equivalent value indicates that there is
