Effective with the November 2022 Letting 119 2023 Standard Specifications 301.2.4.4 By-Product Materials (1) The contractor may provide an aggregate with one of the following by-product materials mixed with crushed gravel, crushed concrete, or crushed stone up to the listed maximum percentage, by weight.In the present study, the effects of two different crushing operations (jaw-cone-vertical shaft impact (VSI): JCV and jaw-horizontal shaft impact (HSI): JH) on coarse aggregate morphology were studied. Angularity, texture, sphericity and F&E of three different sizes of coarse aggregates: passing a sieve of 19 mm and retaining a sieve of 12.5 mm ...

The engineering tests were conducted on the lateritic soil stabilized with additions of (2, 4, 6, 8 and 10 %) PSP and OPC respectively. The result showed that cement gave a progressive increase in ...STRENGTH 10% Fines Aggregate Crushing Value (10% fact), determined in accordance with TMH1 method B2, shall be not less than the appropriate value in table 3602/2, column 3. The Aggregate crushed value(ACV), determined in accordance with TMH1 method B1, shall not exceed the appropriate value in the 3602/3.

Crushed coarse aggregate shall not have more than 50 percent wear at 500 revolutions as determined by ASTM C 131. When the fraction of the ... weight of rollers to compact the material to the required density.

If it were crushed in the manner of a graded aggregate base material, the density would be upwards of 120+ pcf. RAP will be somewhere in the 90 to 95 pcf range, depending on gradation. It varies some depending on the density of you local aggregates used to make the concrete, and on your percentage of voids.Construction Aggregate Calculator. Enter the width, length, thickness, and product density and hit the "Calculate" button to calculate your estimate. If you do not know the product density, use the optional density estimator* or contact a local sales representative. ... An estimated density factor should then appear in the above density ...

Particle size distribution curves of recycled aggregates from concrete pavement crushed by jaw and impact crushers. The jaw crusher produced 85% coarse aggregates (fraction >4.8 mm), whereas the impact crusher produced 82% coarse aggregates. In both cases, the content of particles finer than 0.15 mm was less than 2% mass.The aggregates produced from JH series of crusher had higher texture, higher F&E and lower sphericity compared to JCV crusher. However, aggregates obtained from both JH and JCV crushers had similar angularity. The JH crushed aggregate showed better …
