Full Depth Reclamation (FDR) Hot Mix Asphalt (HMA) and Warm Mix Asphalt (WMA) recycling is the process i n which Reclaimed Asphalt Pavement (RAP) is combined with new materials to produce HMA/WMA mixes. Both batch and drum HMA/WMA plants are used to produce RAP mixes. The RAP material can be obtained by milling or a crushing operation.

Durability of Hot Asphalt Mixtures Containing Reclaimed

The durability potential of bituminous mixtures may be defined as the resistance of the mixture to the continuous and combined damaging effects of water. High durability potential usually implies that the mechanical behavior of the mixture will endure for a long service life. Now, flexible pavement, made of hot-mix asphalt (HMA) with the addition of the reclaimed asphalt pavement granules in

M.S. Genre: Thesis: Subject(s): warm mix asphalt reclaimed asphalt pavement hamburg disk-shaped compact tension: Abstract: Sustainability is a cornerstone of today’s engineering world. Warm mix asphalt (WMA) and reclaimed asphalt pavement (RAP) are the most prominent sustainable materials in asphalt concrete pavements.


Reclaimed asphalt pavement (RAP) is produced either by cold planning (CP) or by heating/softening and removal of the existing aged asphalt pavement. Recycling of the RAP has become more popular since the late 1970’s although it had been practiced as early as 1915. The

HMA Recycling – Pavement Interactive

HMA is one of the most recycled products in the U.S. It is estimated that about 90 million tons of recycled HMA (termed “reclaimed asphalt pavement” or RAP) is used each year in the U.S. ( milled off roads during resurfacing and widening projects each year (NAPA IS 138, ).RAP is typically generated by rehabilitation or reconstruction projects, and nearly every HMA producer uses RAP in

Wirtgen's asphalt plant technology | World Highways

For Benninghoven, a key focus has been on the energy-efficient use of recycled asphalt, with the firm's hot gas generator being one of its latest innovations. Unlike conventional parallel recycling drums, in a recycling drum with a hot gas generator, the reclaimed asphalt pavement is heated indirectly using the counterflow method.

Evaluation of Asphalt Mixture with High Percentage of

This study examined the long-term performance and life span of mixture designs with a high percentage of reclaimed asphalt pavement (RAP) (≥30%) used on higher-tonnage (>5,000 tons) projects. The pavement performance of mixtures containing high RAP percentages and mixtures containing no RAP was compared for the period 1991 to 1999. The pavements analyzed contained a lower structural layer
