and Asphalt Colorado Aggregate Recycling is your supplier of recycled aggregates, producing a variety of grades and types of recycled concrete and recycled asphalt materials customized for your project’s needs and specifications. We have a location in Golden and Colorado Springs. ...
. This could be caused by several reasons such as; non-availability of desired grade, the different grades of coarse aggregate being obtained as a left over from a sister project, etc. In Nigeria, coarse aggregate for concrete is very expensive and thus, the engineer will think...
grades were used namely, 100 pen (penetration grade) straight run bitumen, 50 pen straight run bitumen, and 7 %SBS(styrene-butadiene styrene)modified bitumen. Binder drainage test was conducted onporous asphalt mixturesfor all three binders, results showed that at binder contents greater than 4 ...
Granite aggregate is crushedhard rockof granular structure and originates from magma that erupted on the ground surface and then hardened. In terms of its technical characteristics granite is solid (grades 800–1200) and highly solid (grades 1400–1600), and frost resistant (grades 300–400). ...
Also studied were properties of fresh concretes made from recycled aggregates, gradings of crusher products, properties of recycled aggregates, and the amount of old mortar which remained attached to various grades and size fractions of recycled aggregate....
We observe, both visually and quantitatively, that the performance degrades when noise is added that is larger than or equal to 0.5 rad2, so we consider this the acceptable range for our model, though it can be extended in the future through transfer learning. We then experimentally verified...

The presence of adhered mortar on the surface of crushed concrete aggregate generally degrades the quality of the recycled aggregate and consequently the fresh and hardened properties of concrete made from it. Compared to natural aggregates, recycled concrete aggregates have (Marinković et al., ...
Overall, the results reveal that the introduction of RCA degrades the shear strength, but the degradation degree exhibits a large variability from study to study. Indeed, there are many influential factors, such as RCA type, RCA size, RCA treatment, concrete strength, old mortar volume, crushing...
