Project Organization, Mix Design, and Quality Control

plant operations. First, an overview of types of asphalt plants is given (Section 5). Aggregate storage and han ­ dling (Section 6) and the asphalt cement supply system (Section 7) are then reviewed. Next is a discussion of mixing operations in the three types of plants—batch, parallel-flow drum-mix, and counter-flow drum-mix

SECTION 17 ASPHALT CONCRETE PAVEMENT

The Type of Asphalt Mix to be used shall be as specified. Generally on primary highways (Highway 1 - 216) a Type H2 Asphalt Mix using a 150-200A asphalt cement grade will be specified, and on secondary highways (Highway 500 - 986) and local roads a Type M1 Asphalt Mix using a 200-300A asphalt cement grade will be specified.

New road construction | Applications

Compaction is the final procedure in road construction, its goal being to produce a surface texture of high quality. What aspects need to be considered in asphalt compaction? When compacting an asphalt road, what impact will the road’s location or ambient temperatures have on the compacting operation?

Factors affecting asphalt compaction

The temperature at which an asphalt mix is produced affects both the ease of compaction and the time available for compaction. The time available for compaction increases with mix temperature, but there are limits as to how high the production temperature can be in order to avoid damaging the asphalt binder.
