Crushed concrete is made up of asphalt debris from other construction projects that can be reused to create driveways, pathways, garden beds and more. Development of a 3/4Inch Minus Crushed Base Course ,120 Current Montana specifications exist for a 2inch minus (Grade 5A) and 1½inch minus (Grade 6A) crushed aggregate course (MDT, 2014 §701.02.4); however, because gravel sources in Montana are becoming limited, investigating the use of a gravel specification for maximum particle sizes less than ¾ inch is desirable.
Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or largesize gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soilcement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.Coarse Aggregates: Types, Properites & Applications,1.Size of Coarse Aggregates: The size of the coarse aggregate depends on the use of the concrete is to be poured. For largescale concreting operations without complex reinforcement, large aggregates of size 80 mm, 40 mm, 20 mm are used.

Long term performance of gravel base course layers in,121 The purpose of this project is to investigate the longterm performance of gravel as base course layer material and assess the potential degradation over time. Aggregate degradation is defined as the breakdown of an aggregate into smaller particles [ 2 ]. 2. Pavement test site selection and material sampling.Mix Design of CementStabilized Recycled Aggregate Base ,2012426 The effects of recycled aggregate replacing levels and cement dosage were analyzed based on compaction test. The results showed that the use of 100% recycled concrete aggregates increased the optimum moisture content and decreased the maximum dry density of base course materials compared to those of natural base materials.
