Alex Fraser Group - Asphalt paving, production and laying

Our asphalt plants have a large range of current VicRoads 'General' status registered mixes meeting the sections 407 'Hot Mix Asphalt' and 409 'Warm Mix Asphalt'. Warm Mix uses water to create a foam effect, which provides a better coating of the aggregate, is more workable, and can be delivered a long way from our plants.

influence the RA composition. The presence of geofabric patches significantly affects the usability of recycled asphalt. 4.3.3 Classification of RA Milled or crushed RA can be used in a number of road construction applications. These include its use as an aggregate (and binder) supplement in recycled asphalt paving either with hot or cold mix, a granular base or subbase, or as a fill material.

Paving the Way for Asphalt Recycling and Reclamation

Mar 03, 2017 · Cold Recycling. CR consists of recycling asphalt pavement without the application of heat during the recycling process to produce a rehabilitated pavement. Two subcategories within CR are used to further define CR based on the process used. These processes are CIR (cold in-place recycling) and CCPR (cold central plant recycling).
