Chip Seal Pavement Treatment | RoadResource
A chip seal is a roadway surface treatment that consists of a layer (s) of asphalt binder (hot or emulsion) with a layer (s) of embedded aggregate. Chip seals provide a new skid resistant wearing surface, stops raveling, seals minor cracks, and retards further deterioration of the existing roadway. Chip seal binders can be polymer modified as ...

Technical Approaches to the Recycling of Reclaimed Asphalt
Approximately 99% of reclaimed asphalt pavement (RAP) has been recycled in Japan in recent years. However, the deterioration in quality of repeatedly recycled RAP cannot be prevented through existing methods, nor can sustainability be guaranteed. In addition, it is challenging to procure aggregate and binder. Therefore, to ensure …
Mechanical Performance of Concrete Made with Recycled
The majority of research conducted on recycled aggregate concrete focuses on using recycled coarse aggregates as a granular material [13–15] and as cement stabilised materials in base and subbase layers [16–18]. In contrast, there are few studies on the replacement of coarse and fine aggregate at the same time to prepare recycled …

Preparing Aggregate for Crushing
One other variable to consider in preparing aggregate for crushing is dust suppression. The blasting, drilling, loading, and feeding can generate a lot of aggregate dust that can introduce unnecessary wear on equipment as well as creating a hazardous work environment.
Cold In-Place Recycling – Pavement Interactive
Cold In-Place Recycling. Cold in-place recycling (CIR) is the processing and treatment with bituminous and/or chemical additives of existing HMA pavements without heating to produce a restored pavement layer (AASHTO, 1998 [1] ). It involves the same process of cold plant mix recycling except that it is done in-place by a train of equipment.
Bacterial Treatment of Recycled Concrete Aggregate
Microbial treatment of recycled concrete aggregate (RCA) may improve the quality of the aggregate, and enhance its use in the production of structural concrete and promote the recycling of concrete waste. The mortar phase of the RCA is responsible for the poor performance of the aggregate. Treating the old adhered mortar or removing it …

The aggregate type with the lowest environmental impacts is sand of 0/2 mm produced at the quarry. The aggregate with the highest impact is crushed stone of 16/32 mm from open-pit mining. As expected, crushed aggregates have larger impacts than rolled aggregates due to the mechanisms and equipment needed for their production.
Different types of crushing equipments
Types of crusher depend on the feeding method. These are- Primary crusher, Secondary crusher and Tertiary crusher. The primary crusher is only for the breaking of large stones into pieces (this means primary crusher is not for the aggregate size material.). Examples of primary crushers are jaw crusher; hammer mill crusher and gyratory crusher.
