PAVEMENT REHABILITATION WORKS USING CIPR METHOD ALONG SENAI – DESARU EXPRESSWAY (E22)
Roadbase Structure Reconstruction Method is the use of a combination of existing cement and crusher run (Roadbase strengthening). The main goal is to improve the life of the pavement structure by recycling existing basic road materials. The Cold In Place Recycle (CIPR) method involves the application of Cement-Bound Material (CBM) technology which is a mixture of existing cement and crusher run. The CIPR repair method is evaluated based on the density (during construction) and the performance of the structural strength of the repair (after construction).
ROUTE REPAIR WORKS WITH 'PGM-G' METHODS AT EAST BOUND PACKAGE 1 SENAI – DESARU EXPRESSWAY (E22)
PGM-G paving composites are made of mechanically bonded 100% PP continuous filament nonwoven reinforced by an alkali resistant glass filament grid. This method is suitable for a solution severe wear off and cracked road surface. The process include milling, PMB spraying, laying of PGM-G and laying of ACWC. Refer to above pictures for more info.
GEOGRID METHOD SENAI – DESARU EXPRESSWAY (E22)
Geogrid is a road base structure reconstruction method with the use of geogrid material and an existing crusher run to reinforce the road base. It can minimize the surface deformation and differential settlement.
