Process control for recycled asphalt pavement drum

1992-9-23  8. A method for controlling the gradation in the product of a drum plant for producing asphalt from recycled asphalt pavement (RAP) comprising the steps of: sensing the gradation of the mix (GRAD); comparing the gradation of the mix to a gradiation of the mix desired GRADd; sensing gas volume out of the drum (GASo) when GRAD is greater than GRADd;

Process control for recycled asphalt pavement drum

A process for the production of hot mix asphalt (HMA) by the treatment of virgin material alone or adding reclaimed or recycled asphalt pavement (RAP) (up to 100% of the HMA). The HMA is first heated in either a parallel or a counter flow rotating drum which is supplied with hot combustion gases generated by a remote low NOx burner.

Development of a Lab Production Method with Recycled ...

2012-10-16  First of all since some 20 years in the Netherlands use of recycled asphalt pavement (RAP) at percentages of 50% in hot mixes is standard. All batch plants work with a special added parallel drum. The RAP is dried and pre-heated in the parallel drum to 130°C and added in the pugmill to the extra heated virgin aggregates in the other drum. Another important reason to better control the laboratory process is, that since March 2009 in the Netherlands the CE marking for asphalt mixes has to be applied. For dense asphalt
