Cold In-Place Recycling (CIPR)

sekali-sekala nak jugak kuarkan entry engineering ni. saje nak share aje. untuk sape2 yang search pasal road maintenance ke, kuar jugak entry ni kan. hikss

"Cold In-Place Recycling (CIPR) is a structural pavement rehabilitation technique. It re-uses the existing pavement materials. This technique involves scarifying, stabilizing and re-laying the recycled materials with minimal off-site hauling or mixing.

CIPR involves the processing and stabilizing of the existing pavement layers without heating to produce a rejuvenated pavement layer. There are many types of stabilizing agents that can use in CIPR but the most common are bitumen emulsion, foamed bitumen, lime, cement and fly ash. Stabilising agents can be injected directly into the recycler mixing chamber while the scarifying operation is carried out, ensuring excellent mixing of the stabilizing agent with the scarified materials. Where required, the scarified materials may be modified by the addition of fresh aggregates and/or bitumen."

untuk pengetahuan, projek kat pelabuhan ni adalah my 1st experience pasal CIPR ni. sebelom ni projek CIPR buat kat Sg Koyan tapi masa tu sayee belom masuk keje sini. hari buat trial lay kat sini, sayee amik peluang la nak g jadi witness. leh belajar lagi.

hari ni, sayee nak share gambar pasal CIPR ye.

bayangan sayee

susun simen. ada calculation untuk tentukan satu beg simen untuk brape luas.

kita spray atas jalan tu, untuk keluasan tertentu.

meratakan simen

started

on going

stop kan machine kalau jmpa batu besar seperti ini

untuk pengetahuan lagi, ini adalah gambar masa awal bulan 6 arituh. nnti sayee share plak gambar progress lain dan jugak gambar terkini ye. insyaAllah.
