Dec 01, 2014 Making crushed stone more expensive to use on sites that require pumping of concrete. Crushed stone is typically more expensive to produce due to the additional costs associated with the drilling, blasting, and crushing required to produce the various sizes of aggregate. 6. Crushed stone is preferable to natural gravel in asphaltic concrete.

May 25, 2017 AASHTO American Association of State Highway and Transportation Officials classification method was introduced for selecting soil for the construction of highways and road. In this method the classification is done by considering the Atterberg limit and textural soil classification. The classification is done into seven major groups as, A1

The HMA Pavement Mix Type Selection Guide provides designers with methods for selecting appropriate mix types while considering factors such as traffic, environment, subsurface pavement structure, existing pavement condition and preparation, and economics. The pavement mix types targeted are OGFC, SMA, and fineand coarsegraded dense mixes.
There are two soil classification systems in common use for engineering purposes. The Unified Soil Classification System is used for virtually all geotechnical engineering work except highway and road construction, where the AASHTO soil classification system is used. Both systems use the results of grain size analysis and determinations of Atterberg limits to
Classification of Aggregates Based on Size. Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates.
