The rehabilitation process of asphalt pavements using the technique of milling and filling can cause several environmental problems due to either the disposal of the milled asphalt mix or the exploration of natural resources. One alternative to mitigate these impacts is to reuse this milled material, known as reclaimed asphalt pavement (RAP), in the construction of new pavement layers.

Reclaimed asphalt pavement (RAP) is a common term used for removed and/or reprocessed pavement materials containing a mixture of petroleum-derived asphalt and mineral aggregates (gravel and sand). It is generated when pavement from old roads, parking lots and driveways is removed for reconstruction or resurfacing. RAP can be broken up asphalt
Rejuvenator is to be added in the mixing process to soften the hard binder in the 3. ADVANTAGES OF USING RECLAIMED ASPHALT reclaimed material. Depth of recycling and use of PAVEMNT (RAP) reclaimed materials is same as for cold in-place recycling. Cold in- plant recycling is shown in Fig 5.
In 2018, AAPA published its Reclaimed Asphalt Pavement Management Plan which details its recommendations for the use of RAP across the country. AAPA's recommendation for Australia is that using 15 per cent of RAP is acceptable, as this level does not …
reclaimed asphalt pavement (RAP) is combined with new aggregate and bitumen or recycling agent to produce hot mix asphalt and obtained by pavement milling with rotary drum cold milling machine or from a ripping/crushing operation. This paper described the feasibility of utilizing Reclaimed Asphalt Pavement (RAP) in Warm Mix Asphalt using ing
Figure 2. An integrated approach to using the technologies of reclaimed asphalt pavement (RAP) The variety of existing in the world technologies is constantly updated with new ones with improved economic and environmental performance, such as reduced material consumption, reduced mileage specialized equipment.
Reclaimed asphalt pavement (RAP) can be used as an aggregate in the hot recycling of asphalt paving mixtures in one of two ways. The most common method (conventional recycled hot mix) involves a process in which RAP is combined with aggregate and new asphalt cement in a central mixing plant to produce new hot mix paving mixtures.
The usability of reclaimed asphalt, or recycling, is an absolute necessity of today. We are able to offer you custom-made solutions relating to recycling. Our modern plant technology guarantees you extremely high quality of asphalt using recycling asphalt (RAP). Feed of up to 60% hot recycled material via parallel dryer (below)

Bitumen holds up well, too. Its ageing is limited and can be compensated by using small amounts of new bitumen. Using RAP saves on both aggregate and bitumen costs while reducing emissions, initially and over the lifetime of a road. The latest technology allows the use of RAP percentages up to .
FIGURE 1 Recycling of old asphalt pavement using cold in-place train with emulsion. Table 2 gives a typical cold in-place asphalt recycling design procedure based on practical experience that essentially sim ulates the in-place process. The starting point of asphalt tech nology for most recycled asphalt mix designs is the charac
In 2015, NCAT used this mix design approach for the construction of one CIR and one CCPR test section on US 280 in Lee County, Alabama. Both sections have a four-inch cold recycled layer and a one-inch Superpave mix overlay. For the CIR mixture, the ed asphalt content was 1.8% and the total water content was 4.9%.
