Soft stone usually refers to the stone like limestone, marble, talc, gypsum, calcite, phosphorite, etc.
The classic production line for the soft stone is JAW CRUSHER (primary crusher) + IMPACT CRUSHER (secondary crusher), and with the auxiliaries of vibrating feeder, vibrating screen & belt conveyors.
Regarding of the detail condition, two kinds of techniques are usually adopted in producing manufactured sand, dry way and wet way. Both methods can produce high quality manufactured sand as concrete aggregate. Especially, the dry way can produce not only the manufactured sand used in SMA road surface, but also the powder used in asphalt concrete.

2019-10-19 Aggregate base (AB) is typically made of a recipe of mixing different sizes of crushed rock together forming the aggregate which has certain desirable properties. 20 mm or 3 ⁄ 4 in Aggregate Base, Class 2 , is used in roadways and is an aggregate made of a specific recipe of different sizes and quality of rock inclusive of 20 mm ( 3 ⁄ 4 in) to fine dust.
2014-04-02 Strength is a measure of the ability of an aggregate particle to stand up to pulling or crushing forces. Elasticity measures the "stretch" in a particle. High strength and elasticity are desirable in aggregate base and surface courses. These qualities minimize the rate of disi ntegration and maximize the stability of the compacted material.
2019-11-14 Often referred to as ABC, Aggregate Base Course has desirable properties that make it a top-seller at MDI Rock! This particular rock product contains crushed gravel or stone, which allows it to support the top layer(s) of pavement roadways, concrete slabs, structural foundations, and much more.
Aggregate Base (AB) is typically made of a recipe of mixing different sizes of crushed rock together forming the Aggregate which has certain desirable properties. 3/4 inch Aggregate Base, Class 2, is used in roadways and is an aggregate made of a specific recipe of different sizes and quality of rock inclusive of 3⁄4 in (19.05 mm) to fine dust.
Angular aggregates increase the void content. Larger sizes of well-graded aggregate and improved grading decrease the void content. Absorption and surface moisture of aggregate are measured when selecting aggregate because the internal structure of aggregate is made up of solid material and voids that may or may not contain water.
2014-04-02 because of other characteristics that make them desirable, including skid resistance, economics, etc. The maximum percentage of absorption allowed by the Standard Specifications is 5.0 percent and applies to aggregate classes AP, AS, A, B, and C only. Abrasion Resistance Abrasion resistance applies only to coarse aggregates.
Aggregate physical properties are the most readily apparent aggregate properties and they also have the most direct effect on how an aggregate performs as either a pavement material constituent or by itself as a base or subbase material. Commonly measured physical aggregate

Some natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural ...
2019-11-10 Aggregate base (AB) is typically made of a recipe of mixing different sizes of crushed rock together forming the aggregate which has certain desirable properties. 20 mm or 3 ⁄ 4 in Aggregate Base, Class 2 , is used in roadways and is an aggregate made of a specific recipe of different sizes and quality of rock inclusive of 20 mm ( 3 ⁄ 4 in) to fine dust.
2015-01-06 AGGREGATE BASE In certain situations graded aggregate base construction may be desirable. Aggregate base is placed between the HMA courses of the pavement and the compacted subgrade. For best performance, the aggregate base should be well-graded, consist of predominantly angular particles, have a maximum
2019-11-13 Effects of Aggregate Gradation on Resilient Modulus and CBR in Unbound Granular Materials Mohsen Aboutalebi Esfahani1, ... together with other considerations mentioned in the related regulations have yielded desirable results in many cases. However, ... mechanical properties of aggregate base and sub-base granular materials in Minnesota.
This project established the desirable materials properties (permeability and resilient modulus) for the two types of free-draining base materials and establishes a more stable gradation for the open-graded aggregate base. Appropriate layer and drainage coefficients for use in the AASHTO design of permeable base sections are also determined.
By volume, aggregate generally accounts for 92 to 96 percent of Bituminous concrete and about 70 to 80 percent of Portland cement concrete. Aggregate is also used for base and sub-base courses for both flexible and rigid pavements. Aggregates can either be natural or manufactured.

Roads and Parking Areas: For aggregate base course roads and parking areas, the top six (6) inches of topsoil shall be stripped within the area to be aggregate surfaced.
2006-11-02 aggregate. The mineralogy of the base aggregate was found to make a significant difference in the strength of the CTA, with strength increasing in the following order: mica, limestone, and diabase. The granite aggregate yielded variable results, but the strengths were generally on the order of those determined for the diabase aggregate.
