Aggregates for Chip and Seal Pavement

As solid as aggregate may be to the naked eye, most aggregate particles have voids, which are natural pores that are filled with air or water. These voids or pores influence the specific gravity and absorption of the aggregate materials. Figure 3-1. Aggregate Specific Gravities.

The usual water cement ratio is 45% (5.2 gal/sack) of dry cement; 500 gal per cementing unit should be provided for priming, testing, and cleaning up. An additional 5130 gal should be provided as a minimum safety margin. Rate of water supply should be based on the rate of mixing cement: usually this is 5-6 bbl/min. for each pumping unit on the job.

Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Water, at a temperature of 73.4°F (23°C) has a specific gravity of 1. Specific Gravity is important for several reasons. Some deleterious particles are lighter than the good aggregates.

Cement - Wikipedia

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is …
