The aggregate base recommended for use is ODOT Item 304. The material is a high quality, dense graded, crushed aggregate. The particle size gradation should be uniform from coarse to fine and the upper limit on the very fine fraction (passing the No. 200 sieve) should not be exceeded. An excess
DenseGraded Mixtures: Advantages • Good interlock of aggregate particles if compacted well • Relatively low permeability if compacted well • Strength and stiffness derived from binder and aggregate structure • In NJ, generally a "stiff" mix • Cheaper than other asphalt mixture types – .
Untreated Aggregate Base Construction The untreated aggregate base course should consist of one or mor e layers placed dir ectly on the prepared subgrade. It should be spread and compacted to the uniform thickness and density as required on the plans. The minimum thickness of untr eated aggr egate is 4 inches. The aggregate material should be ...
09/12/2013 · A base layer of densegraded aggregate, with a mix of particles sizes tightly packed together, will generally provide the most structural support for the pavement surface. On the other hand, opengraded or gapgraded bases with fewer small or intermediatesize particles may be more effective for drainage purposes.

Densegraded mixes are the most common. They incorporate wellgraded aggregate and 5 to 6 percent asphalt binder (by weight of mix). They are designed to be impermeable, which means they minimize water getting to the layer below them. Gapgraded mixes, such as stone matrix asphalt (SMA), provide an excellent surface course.
ii Abstract: Cementtreated base (CTB) is a mixedinplace or centralplantproduced material consisting of soil/aggregate, cement, and water that creates a strong and durable stabilized roadway base. This guide to CTB discusses its appliions, benefits, design, construction, testing, and performance.
