ASTM's road and paving standards provide the specifiions and test methods pertinent to the material, physical, mechanical, performance, and appliion requirements of road surfaces and pavements. These geotechnical surfaces are laid down on specified areas intended to sustain either or both foot and vehicular traffic. The types of paving covered by these standards are typically made of ...
This specifiion covers the requirements for granular aggregate materials for use in subgrade, subbase, base, gravel surface course, shouldering and bedding and backfill to sewers, culverts, and other structures. Specifiion Significance and Use . This specifiion is written as a provincialoriented specifiion. Provincialoriented specifiions are developed to reflect the ...

The road bed must be prepared and layers of support are added. These support layers consist of aggregates such as gravel, small stones, ground stone or sand. Each layer provides a base for the layer above. In this manner, the road surface is supported as vehicles go over it. These layers are also a foundation that helps contain and control rain water to keep the road surface as safe as possible.
Our aggregates solutions. Discover our high value aggregates and solutions — a full range of crushed rock, stone, sand, and gravel that are used in dozens of appliions, including readymixed and precast concrete, asphalt, and as a base material for street and road construction. We offer the best quality in terms of particle shape, durability and resistance to weathering, so
The following test methods, will be utilized in the laboratory evaluations of the Aggregate materials submitted for Aggregate Source Approval. Each material type tested will have its own assigned test methods specific to the material being tested. The Standard Specifiion section and sub section numbers are listed for easy reference. Test Methods may be from AASHTO, ASTM, or DOTD, etc. .
Road base, flexible base or flex base, is finely crushed rock that serves as base material for a variety of construction projects. It is one of our core materials. We supply crushed limestone flex base and crushed concrete flex base that meets Texas Department of Transportation specifiions.

Strategies for aggregates include reducing aggregate use by using recycled waste materials, using more durable aggregates to maximize pavement life, reducing hauling distances by selecting local materials, and improving aggregate acquisition and processing. Building on the publiion, FHWA offered a 10part webinar series in 2019 and 2020 on the key concepts and practices related to ...
Development of performancebased material specifiions is critical for optimized material use with reduced waste and eventually better utilization of construction dollars. From a MEPDG perspective, determining the best use of different qualities of locally available aggregate materials in road bases/subbases may be a challenge. For example ...
Road base is a mixture of aggregate material used as the base for road paving, which is typically made from quarry material. The quarry process and operation will involve the following aspects: deforestation of the land designated for the quarry site, site preparation, set up of machinery, operation of machinery, blasting, onsite transportation, onsite processing and transportation to ...
· Aggregates are the most mined material in the world. Construction aggregate is a broad egory of granular raw material of different sizes (sand, gravel, crushed stone, slag, recycled concrete etc) used in construction. Aggregate can be used in a number of ways in construction. In roads and railway ballast the aggregates are used to resist the overall (static as well as
