According to the document 8620/BGTVT-KHCN of Ministry of Transportation on August 20th 2013, from the date Jan 05th 2014 until Jan 08th2014 , BMT Construction & Investment J.S.C. in conjunction with Science and Technology Department of Ministry of Transport, Institute of Transport Science and Technology, Road Laboratory III and IDICO Infrastructure Development Investment J.S.C. will deploy the trial producing and road paving using “Hot mix asphalt recycling in plant” technology on National Highway 1A – Section from Km 1908+200 to 1908+640 in the interval An Suong – An Lac (right side – the direction from HCMC to Tien Giang)

Asphalt recycling with batch mixing plant at BMT

Basically hot mix recycling in BMT plants follows next processes:

1)   Scratch removing old asphalt layers from the existing pavements;

2)  Transportation of materials to mixing plant and storage in the repository;

3)  Crushing RAP and classifying by appropriate aggregate sizes;

4)  Conveying RAP on hopper and transporting to the mixer to mix with virgin materials according to the gradation designed from the laboratory;

5) Transporting  asphalt mixture to the construction site for paving.
